RequestFactory, frozen autobeans, and MVP
I'm trying to convert an app from using plain JSON to using RequestFactory. The app has a view and presenter. So, I use the RequestFactory to get Contact instances, and pass them on the view to edit. But, the editing runs into an issue with the AutoBean being frozen. Without MVP, I would just open a request, invoke edit and pass the bean, and be done. But, it doesn't seem right to now do that in the view. And, I have an issue with holding a request open just to enable editing the bean, when it's conceivable that the user will bail out and not end up saving their changes. So, what would the best flow be for this situation? -- You received this message because you are subscribed to the Google Groups "GWT Users" group.

Re: How to figure out HTMLPanel rendering is complete
I think there are three things that need to happen each time you get more content, at least two of which are asynchronous: 1. your ajax call to get content, asynchronous 2. when you place received HTML code into document, browser will start to render HTML, but without the images yet. I believe that if you run the deferred command as suggested just after setting the HTML content into the panel, it will run when the HTML is fully rendered, but w/o any images in place 3. browser will start to load referenced images (from img tags src attributes) and other items with src, possibly in parallel with the rendering of the HTML If you really don't want to start loading any new content until the HTML and images are fully loaded, then you would need some mechanism to know when all the images are complete. You might actually want to still use a deferred command at this point, since the point in time where images are loaded is probably earlier than the point where they are actually rendered. You can help out the process if you control the incoming HTML, by using height and width attributes in the img tags. That way the placeholders will be sized immediately, and you wouldn't have to wait until they have loaded. Unfortunately, I believe that this gets in the way of responsive design, since it prevents a max-width css rule from working correctly.

Re: CellTable - How to programmatically start editing a cell.
Found this old thread, and thought it worth commenting.
I took a variant of Ralf's approach in an effort to get tabbing/enter key
movement to the next cell. In my recreation of EditTextCell, I revised the
commit method:
private void commit(Context context, final Element parent, ViewData
viewData,
ValueUpdaterString valueUpdater)
{
String value = updateViewData(parent, viewData, false);
clearInput(getInputElement(parent));
setValue(context, parent, viewData.getOriginal());
if (valueUpdater != null)
{
valueUpdater.update(value);
}
Scheduler.get().scheduleDeferred(new Scheduler.ScheduledCommand() {
@Override
public void execute()
{
NativeEvent clickEvent = Document.get().createClickEvent(1, 0,
0, 0, 0, false, false, false, false);
Element td = parent.getParentElement();
Element nextTd = td.getNextSiblingElement();
if (nextTd != null){
nextTd.dispatchEvent(clickEvent);
}
}
});
}
It seems to work, and has the benefit that I don't need to extend or
rewrite every possible editable cell type.
But, I don't know if there are any pitfalls that I've missed, other than it
won't jump over a non-editable column to the subsequent editable column,
and it won't jump to the next row.

Re: How to figure out HTMLPanel rendering is complete
I'm guessing that you're doing incremental loading - that as soon as the
user reaches the bottom of the current content, you get more?
You could remove the scroll handler when you start to load the HTML, and
then restore it when the HTML has been received. Or have the loading
mechanism set a flag and unset it when done, and the scroll handler checks
that flag before doing anything (maybe better to use an integer count,
increment when starting load, decrement when complete, and scrolll handler
only works when it's zero. But, if there are images in the received
content, they will be loading asynchronously after that, which will affect
the size of the content. The best* way I can think of to handle that is to
scan the received HTML looking for img tags, and then add a native JS
load/error handler to each one, and keep a running count. the load handler
would decrement the count, and, when it reaches 0, all images will be
loaded. You might still need a deferred command, since just because the
image has loaded doesn't mean that the DOM has reflowed.
*Maybe the second best way. If you used an iframe as your loader instead
of GWT's Ajax mechanism, you could set a readystatechange handler.
ReadyState 4 is supposed to mean that everything has been received,
including images. But, I don't know how well supported that is across
browsers.

the server to fetch content continuously. New scroll events are being fired
while the content fetched from the server is being rendered. We would not
want this i.e while the content is being rendered we do not want the
ScrollEvent to be fired. I tried the above code where I have attached
AttachEvent.Handler() to contentPanel. A flag isRenderComplete is
maintained which is turned true on contentPanel attach. This flag is used
in the onScroll method before triggering any server call.This approach
seems to work.
But I am not sure if this is the correct one. Does anyone has any better
solution[s] ?If the content has images and other external stuff will they
be loaded before AttachEvent is fired ?
Also since we are creating new contentPanel everytime each fetch takes the
scrollbar to the top. I tried to add a new HTMLPanel markerPanel with
couple of line breaks to the contentPanel. Then in the onAttachOrDetach()
of contentPanel tried to scroll to the markerPanel. This did not work.

Using datagrid.redrawRow after failed cell validation
I'm updating a double value in a datagrid to using a custom parser on an
EditTextCell. If the parser throws an error, then I'm trying to put the
original value back by redrawing the row. But, the erroneous value stays
in place. Stepping through the code, I do see it going through
HasDataPresenter's setRowData method, and even see the original value in
the row object. But, that value doesn't get drawn.
If I now click on the cell again, then click away without editing, then the
original value does get written into the cell. That led me to try a
deferred command, which didn't work, hence code below with a ridiculous
delay before redrawing (which, needless to say, also doesn't work).
If it makes any difference, I'm using a SingleSelectionModel.
Am I doing something wrong here? Or is there a better way to check the
values as they're being entered?
@Override
public void update(final int index, R item, String value)
{
double doubleValue = 0.0;
boolean needsRedraw = false;
try
{
if (value != null !value.isEmpty())
{
doubleValue = MyFormat.PARSER.parse(value);
needsRedraw = true; // added
}
item.setAmt(doubleValue);
thisCell.clearViewData(item);
}

{
needsRedraw = true;

{
//grid.redrawRow(index);

I've tried using a JSP to generate a block of HTML dynamically, usually including looping, and retrieve that using RequestBuilder, and putting that into an HTMLPanel. The only difficult part is managing the id's of various elements. And of course, having half the code in src, and the other half under war - but I could use a generator class under src to get around that. It seems that a dynamic version of UiBinder or UiRenderer would be possible, since GWT has client runtime XML processing capabilities. And the set of available tags could be expanded to include some analogs to the JSP core tags, like c:forEach. The Java class would have to be created in advance, so either there would need to be fields for all possible widgets, with nulls legal, or the widgets could be entries in a map instead of class properties. Widgets resulting from a loop would be in an array or List.

java.util.Date emulation Year 00 issue
If I use a com.google.gwt.i18n.client.DateTimeFormat with my own pattern, like -MM-dd, I run into the situation described in the Javadocs under Additional Parsing Considerations if the user enters a two digit year 00 (most likely intending it to be the year 2000). The following code: DateTimeFormat fmt = DateTimeFormat.getFormat(-MM-dd); Date d = fmt.parse(00-01-01); System.out.println(d + getYear: + d.getYear() + getTime: + d.getTime()); long d1 = d.getTime(); d = fmt.parse(01-01-01); System.out.println(d + getYear: + d.getYear() + getTime: + d.getTime()); long d2 = d.getTime(); long diff = d2 - d1; System.out.println((diff/1000.0/60/60/24/366)); Results in: Thu Jan 01 00:00:00 EST 1 getYear: -1899 getTime: -6216737400 Sat Jan 01 00:00:00 EST 1 getYear: -1899 getTime: -6213575160 1.0 So, I believe that internally the date is on the right year, since the two dates are different by 366 days (apparently year 0 was a leap year), but when getting the year from it, it adjusts year 0 to 1. This is messing up logic I have with a custom extension of DateTimeFormat to adjust how two-digit years are parsed - the first step in parse is super.parse(text), and then I do my own adjustment by 1900 or 2000 after that. So, entries of 00 are being turned into 2001. This is actually a Java problem, and we can get into a long metaphysical discussion of whether there really should be a year 0 or not, but it does affect parsing, and I believe that the way that DateTimeFormat handles two-digit years supplied to a pattern brings it to the forefront. So, the question is, should GWT's Date emulation be faithful to its Java equivalent, or behave in a manner consistent with DateTimeFormat? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: extend UiBinder engine
For those us that might encounter this need for somewhat simple situations,
why not use a @UiFactory? That provides a reasonably clean solution that
separates the security aspects.
Provide a parameter like roles to the create method, which could parse a
comma-separated list of roles in a string to determine whether to show or
hide.
g:FlowPanel
g:TextBox addStyleNames=test ui:field=txtA
roles=admin,sales/
g:TextBox addStyleNames=test ui:field=txtB roles=guest/
/g:FlowPanel
@UiFactory
public TextBox create(String roles) {
TextBox txtBox = new TextBox();
txtBox.setVisible(Roles.hasAccess(roles));
return txtBox;
}
}
Roles would know the current user role(s) and determine if one of the roles
in the user matches one of the valid roles for the widget.
It would be nice if the UiFactory methods could somehow be separated out
into their own class for reuse, but I don't think that's possible.

Yeah, that would be useful. I'm kind of curious about the part: I'd like to see something a bit more advanced where you don't need to declare the @UiFields.

empty table widget size and reuse
I'd like to have an empty table widget in a DataGrid, which would cover the entire width and height of the table area. Basically, I'd like to just have a vertically and horizontally centered label. Right now I can only get one that occupies the minimum area it needs based on it's content size, or I could fix a size in px. But, trying to set the size to 100% for width and/or height has no effect, because it gets put inside a table that I believe I have no code access to. And that table has no sizing specified. Is there a way to do this? Question 2: I'd also like to have just one of these, to use across multiple grids. But, assigning the same widget instance to all my grids doesn't work - I don't see it. I suspect that it would show up for the last grid I added it to, if I can figure out which one that is. It seems that the grid widget could store the reference and reattach it each time it's needed, allowing one single instance to be reused. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Override html styles with css resource
I wouldn't say that the recommended way to create CSS is to use
CssResource. If I just want to create general styling, there's nothing
wrong with the CSS-file-in-the-war-directory approach.
Keep in mind that using a CssResource will require a full recompile if you
change anything, while just changing the linked CSS file in the war
directory won't.

I see in classes like EditTextCell that the templates assign a tabindex of -1, so this behavior seems unavailable by design, and I fear that the code to achieve it might be pretty horrendous. But, this is one situation where behaves like Access would be nice. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Inline style vs class for cell renderer
I'm wondering if anyone has done any efficiency testing on using inline
styles vs class in cell renderers. Right now I'm using a template with two
methods:
@Template(div style='text-align:right'{0}/div)
public SafeHtml valid(String value);
@Template(div style='text-align:right' class='{1}'{0}/div)
public SafeHtml invalid(String value, String invalidStyle);
I used an inline style for the text-alignment, but it occurred to me that I
could use a class for that instead if it would be rendered more efficiently
by the browser. Has anyone tried comparing the two approaches?

Re: Custom widget with custom UiBinder markup
Some additional questions in the absence of a full dev guide:
1. What about a class that extends TabLayoutPanel? I can write and
annotate a method addTab(Widget w) in order to use the xxx:tab child
instead of g:tab, but what about the grandchild g:header that the
g:tab could have had?
2. Can the first parameter to the annotated method be a subclass of Widget
to restrict the possible types?

Re: SplitLayoutPanel particulars
AFAIK, there is no way to disable a splitter in SplitLayoutPanel. But, you can use a plain LayoutPanel as the container, and its children would be the original right side widget, and the left side as a SplitLayoutPanel with just two pieces (probably West and Center). So, the former East part wouldn't be in the SplitLayoutPanel any more, it would be in the container LayoutPanel.

Latest Google Eclipse update has hosed my Eclipse
I just updated my Google plugin for Eclipse, per a notification that popped up this morning. My current project now shows a lot of errors, and several error dialogs pop up when I try to open an existing GWT project workspace. Java editors and some other panes, like the class outline, just show big red X's. The errors I get are JVM version is 1.0.0; version 1.7.0 or later is needed to run Google Plugin for Eclipse. I can't pull up most of the Google-related properties, either. They show an error popup the first time I go to use them, and then just an error message in the panel after that. I tried pointing Eclipse to my JRE1.7, but that didn't help. I really hope that I don't need to set 1.7 as the Java version for GWT projects now, since several current projects are tied to 1.6,and changing that is not in my control. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Firing a ChangeEvent from a widget that wouldn't natively fire one
Jens,
Thanks for the comments ... See below
On Saturday, December 14, 2013 8:42:06 AM UTC-5, Jens wrote:
Is there any reason to be concerned about firing a ChangeEvent from a
composite based on a FlowPanel?
I'm trying to track user edits within a form, in order to set a dirty
data flag. Sometimes the form has subforms, each of which has it's own
data dirty tracking. Basically, I'm handling ChangeEvents and
ValueChangeEvents within the subform, and when those occur, I'm firing a
ChangeEvent from the subform. It all seems to work, but I have a vague
discomfort with it, knowing that things like textboxes and selects natively
fire change events, but div tags don't. Is all the event management
related to manually fired change events done entirely in GWT?
Not sure if that has any bad consequences but I would guess it does not.
Maybe some old IE's have bugs regarding event bubble'ing for change events.
That was one of my main concerns. It works in IE10s emulation of IE8, but
I've found that that emulation is far from perfect. Some things work in it
that don't work in a real IE8. Fortunately, I'm not concerned with earlier
IE.
However, as dirty tracking is a logical thing I would fire a logical event
and not a DOM event. I think I would have created a
DirtyEvent/FormEditedEvent + Handler. Alternatively you could also create
an interface DirtyTracker that has some methods like
setDirty(Form/IsWidget) and have the top most class that controls your form
hierarchy handle the dirtiness of all forms (you would pass the
DirtyTracker down the Form hierarchy, and each form would call
setDirty(this) if it detects that it is dirty).
I'm actually going to fire an event like that from the panel containing all
the widgets, but need to know when to do that. And, what I'm writing is a
sort of framework to simplify things for folks writing the view classes, so
the abstract base view has:
protected void setChangeHandler(HasChangeHandlers ... widgets)
{
for (HasChangeHandlers widget : widgets)
{
widget.addChangeHandler(dataChangeHandler);
}
}
and they can just pass it a list of widgets
I may end up switching that to use ValueChangeHandlers instead, since
almost every data widget fires them. But, ListBox doesn't implement
HasValueChangeHandlers, because it has no concept of value. But, I already
extend ListBox to give it setValue and getValue for strings, so I can fire
a ValueChangeEventString. But, where that leaves me uncomfortable is
that I don't consider that my subforms' overall concept of a value have
changed, If they did, then I'd have to grab the value of the bean every
time one field changed in order to supply a value with the event, or turn
the change handling off after the first invocation makes it dirty, and then
turn it back on again if the form is reset, or newly populated. Or, I'd
have to implement firing the data dirty event from the subforms as well,
which might be the best way to go. But, then the subforms in the main view
need to be treated separately from the plain widgets, so I'd need two
methods like the above, and users would have to invoke both, separating
their components into widgets vs subforms.
I also tried writing an overload of the above method using
HasValueChangeHandlers ..., but that isn't distinguishable from the first
version, according to the compiler.
I suppose another approach would be to use Widget ..., and then test what
the item is an instanceof. But then what to do if an item isn't either one
- ignore it, or throw an exception?
This is one place where it would be nice to have mixins - so I could just
add some more logic to things like ValueBoxBase to fire my own custom value.
As an aside, it's a little weird that ListBox fires ChangeEvent, and not
ValueChangeEvent, while ValueListBox fires ValueChangeEvent but not
ChangeEvent, given that they're both based on select tags.
They serve different purpose. ListBox is the direct wrapper of the select
tag while ValueListBox works on a higher level as it can deal with any kind
of values not just strings. The fact that ValueListBox uses a ListBox
internally is an implementation detail.
I can see that, I guess what baffles me is why ListBox doesn't fire
ValueChangeEventString, or ValueChangeEventInteger
And, on a related note, it seems weird to me that many of the ValueBoxBase
classes don't have a primary style, so that, for example, a TextBox looks
different than an IntegerBox

ListBox and default selection
In plain old HTML, I can create a select tag, and specify one option as selected, so that it comes up as the selection by default, or gets selected if the user resets the form. GWT doesn't appear to offer this capability - I don't see anything like setDefaultSelectedIndex(int index), or addItem(String itemText, boolean defaultSelected). Is this an oversight, or something that was done deliberately? The situation I'd like to use it for is a set of enumerated column values from a DB, to be listed in alphabetical order, but where the default value isn't the first. As it stands now, I'm going to have to keep track of the proper index to select when the form is cleared, as opposed to getting it done once when I initially set up the form. Hmm, that being said, it seems like there's no reset capability anyway - a ResetButton apparently belongs only in a FormPanel, and there's no reset method in ListBox. I suspect that I'm going to have to extend ListBox to provide a way to set a default selected index AND a reset capability. So, this turned into more of a rant than a question, but I'd still be interested in hearing if there was a specific reason those capabilities were left out, or if my anticipated extensions are a bad idea for some reason I haven't thought of. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Changing css without recompiling
There are a number of different tricks you can use for dynamic styling.
Because the StyleInjector is going to append to the head section, any style
tags it injects will come after any existing content. One simple way to
get your styles to override later appearing ones is to give the body tag
an id, and then include that id in your rules. The resulting rule will have
higher priority/precedence. Like: body#myid .gwt-Label { ... }
You can use RequestBuilder to retrieve the CSS file via Ajax, then inject
the resulting string using the StyleInjector.
If your changes are just things like colors and background-image urls, and
there aren't too many, you can write a class with static get methods to
retrieve various values, like a color or url string. Populate the static
fields backing those methods before injecting your CSS resource, and use
things like @eval in the resource to retrieve the values within a rule.
If you actually want to replace CSS at runtime - to reskin for some reason,
the only way I can think of to do that would be to manually create your own
style element, and set it's inner HTML to the contents of an Ajax-retrieved
CSS file. To change the styling, retrieve the alternate CSS file, and
overwrite the contents of your style tag. (I suppose it could be populated
in the initial HTML, but given an id so you can access it later to replace
the rules.)

Hi all,
My problem is related to this blog post -
http://googlewebtoolkit.blogspot.com.au/2011/03/styling-and-skinning-your-apps-with.html.
Namely, I have a gwt app, using UIBinder that I wish to be able to style
without recompiling. I have a 'default' style that is defined in a css in
the src packages and included in all the *.ui.xml templates via the
ui:style src=.../ tag.
Now I wish to be able to change the default style at runtime, but without
recompiling. The link above suggests this is possible, and my understanding
is also that they have default styles in the ui.xml files and then they
override it in the static stylesheet included by the host html.
I've tried this, deployed my app (in dev mode) with the following
organisation:
- the uibinder templates all reference a css file in a src package via the
ui:style src=.../ tag
- now my host.html also link's a different css where I use the same
selectors with different values to override the style.
This does NOT work! The externally linked css seems to have no effect.
Looking at the generated html, I can see the styles from the src package
being obfuscated, but the linked css (when I click on the link) is as
normal - no obfuscation. I am guessing that is part of the problem since
the generated html elements definitely reference the obfuscated selector
names.
Any ideas/hints on how to get this work or where I am going wrong?
Thanks!

Re: Using Object in classes passed via GWT RPC
I don't see what you're talking about in the error printout, but do see a
bunch of other things. One thing I found out the hard way is that you
can't serialize a sublist - I have always assumed that it contains ties
back to the original list, which would cause issues when serializing (like
the framework would have to send the whole list anyway because of the
back-link to it).
So, there may be other problems that are causing the initial problem, and
then not-so-clear error messages implying something else.
Also, if I was going to have an Object field, I would type it as
Serializable instead.

If I change the Object field to type String, the compiler is happy.
The thing that has me stumped is that I have other methods in the same RPC
service that return similar objects containing Object fields and these are
working correctly. I also have an RPC-based event mechanism that is
returning event classes that contain MapString,Object and these appear to

serialization code generated for those types.
Am I doing something wrong? I see the documentation says I can't return
Object, but it's been working for a couple of years.
Is there a better way to accomplish this?

PropertyType is a simple enum.
LocalizedMessage is a serializable class containing only String and
ListString fields and is used extensively in other RPC calls.

It refers me to some generated code, which begins with:
public class PurchasingView__Context extends

And, as you might imagine, the methods it contains relate to String, not
Company.
I don't currently have get/setValue, but tried those as well, assuming
that getValue ought to return driver.flush(), and setValue(Company value)
ought to do driver.edit(value) - needless to say, that didn't help
What am I missing here to get it to recognize that it should be editing a

Re: How to wire multiple editor to same bean.
In trying Daniel's approach, I have a primary view class CompanyView
implementing EditorCompany. It has several child AddressView objects,
which implement EditorAddress; there are several Address fields in the
Company. They get populated without my AddressView class ever invoking
driver.edit or driver.flush (and I don't seem to need any set or getValue
methods). But, that's just an aside.
I then created a sub-editor PurchasingView also implementing
EditorCompany, since the related data is in single fields within Company,
instead of a sub-object.
@UiField @Editor.Path()
PurchasingView purchasingView;
I assumed that the PurchasingView should define and GWT.create it's own
driver interface, and that it's constructor should initialize that driver.
When the time comes to edit the Company in the outer view in DevMode, or
when I compile, I get the following error:
Type mismatch: cannot convert from Company to String
It refers me to some generated code, which begins with:
public class PurchasingView__Context extends
com.google.gwt.editor.client.impl.AbstractEditorContextjava.lang.String {
And, as you might imagine, the methods it contains relate to String, not
Company.
I don't currently have get/setValue, but tried those as well, assuming that
getValue ought to return driver.flush(), and setValue(Company value) ought
to do driver.edit(value) - needless to say, that didn't help
What am I missing here to get it to recognize that it should be editing a
Company, not a String?

So suppose we have a big bean or proxy having a many fields. A good

Re: Error when defining a generic Composite widget using Java Generics
I think you're code to set the id is running before there is any DOM peer

in an attach handler, or in a method that I know won't get invoked until
the widget has been attached to the DOM.

You're getting a weird behavior with the height of the select because you
didn't set any vertical sizing parameters for it when you added it, so it's
defaulting to top and bottom of 0. Thus the selector part of it is huge.
(And FF does honor the bottom: 0; setting.)
Here's a revision of your code with a comparison of adding a container:
public void onModuleLoad() {
ListBox list = new ListBox(false);
RootLayoutPanel.get().add(list);
RootLayoutPanel.get().setWidgetTopHeight(list, 0, Unit.PCT, 50,
Unit.PCT);
RootLayoutPanel.get().setWidgetLeftWidth(list, 0, Unit.PCT, 50,
Unit.PCT);
list.getElement().getStyle().setWidth(100, Unit.PCT); // closer to
what you want
for (int i = 0; i 100; i++) {
list.addItem(item + i);
}
ListBox list2 = new ListBox(false);
FlowPanel pnl = new FlowPanel();
pnl.add(list2);
RootLayoutPanel.get().add(pnl);
pnl.getElement().getStyle().setBorderStyle(BorderStyle.SOLID);
pnl.getElement().getStyle().setBorderColor(black);
pnl.getElement().getStyle().setBorderWidth(1, Unit.PX);
list2.getElement().getStyle().setWidth(100, Unit.PCT);
RootLayoutPanel.get().setWidgetRightWidth(pnl, 0, Unit.PCT, 50,
Unit.PCT);
for (int i = 0; i 100; i++) {

I don't think that there's any relation between this and issues you might
be having with Canvas.

Re: How to use different CSS/Code for different browsers/devices/os?
1. The problem with GWT's conditional CSS is that it is evaluated once, at
the time the CSS resource is processed, which means that you won't get
runtime changes if the user changes the window size (or a mobile user
changes the orientation).
2. The problem with media queries in the CSS is that GWT's CSS resources
don't (as of the last time I looked) support them.
3. Another problem with media queries is that IE6-8- don't support them.
My solution has been to:
1 2: have a separate CSS resource for each media query, but without the
query within it. Instead, get the CSS string from the resource and wrap
the query around it yourself, and then inject the resulting string.
3: have yet another variation of each resource, for IE6-8, where there is a
marker class in front of every selector, like:
Base resource for @media (min-width: 400px) and (max-width: 639px):
.special { color: red; }
IE6-8 version:
@external .ie_400_639;
.ie_400_639 .special { color: red; }
Then, for IE6-8, use a window resize handler to manage adding the
appropriate class to the html tag (and, of course, removing any outdated
class). Run that when the entrypoint class loads as well.
Yeah, part 3 is a pain to manage - I ended up creating a Java tool to
manually run the CSS through to create the IE versions using a horrendously
complicated RegEx.

How can this best be done to optimal use GWT (code splitting, code

My thoughts: Use different Factory classes for different

Then select the correct factory through GWT config files by indicating

Is this the way to go ? Or/And maybe use Mgwt and let it handle it

Re: Is there any way to have event handlers for a cell in a CellTable that isn't in a column?
The header concept gets me a lot further down the path, and it looks like I can fake it out by having a Header rendered in the footer section. But, I'm still not getting my actions triggered, whether the Header is rendered in a header section or footer section. There's probably a piece that I've miscoded that's causing this, but the issue I'm seeing when I step through my code is that for a mouseover event, which I'm not handling in any way, the AbstractHeaderBuilder execution flows through public Header? getHeader(Element elem), and is passed the TD element. But, with a click, I see it is passed the Button tag from my action cell, and ends up returning null. (I'm using the abstract class' renderHeader method to do the rendering, and see the ID on the TD tag, which seems essential.)

Re: Is there any way to have event handlers for a cell in a CellTable that isn't in a column?
Actually, I'm using my own parallel to ActionCell that copies most of it's code and adds a few things. I couldn't extend ActionCell directly due to something with private or package access, if I recall correctly. I've used that same cell in columns and it's worked OK. (Sorry about the red herring with ButtonCell - I was speaking generally about a cell with a button, and forgot that there actually was a ButtonCell.) I've added a CellPreviewHandler to the table to print a console message when invoked, and also print a console line from onBrowserEvent in my ActionCell, and neither of them triggers when I click my buttons. Looking though the code for several of the API classes involved, it seems that the event path goes through the columns. (As an aside, I'm not all that fond of using an updater when there's nothing to update - somewhat the same line of reasoning that keeps me from just adding a column. But I've seen that approach taken in a few examples, like the CustomDataGrid, although that also has the associated cells in a column.)

Re: Dirty Form Flag in GWT or basically how to identify if in the form if there are any unsaved changes
jaga, If you're going to update the model object with every change, then it seems that you'd need a value change handler on every form field. I've usually implemented this concept by having a single inner class ValueChangeHandler instance for the form composite, along with a boolean dirty field. The handler gets added to every form field. Given that there's a single handler instance, I don't think that takes up too much memory. You can cut down the amount of code you have to write by creating a utility method, something like addWithHandler(HasValueChangeHandlers widget, ValueChangeHandler handler) that adds the handler to the widget and then delegates to the panel's add method - with appropriate variations for panels that have parametrized add methods. In the onValueChange method I check the dirty flag - if it's false, I set it to true and fire a custom DataDirty event (which is just a simple custom event with no special fields - usually the only thing I'm interested in is the event source, which I can get from the inherited getSource method). Then my external logic can add whatever I want as a handler. That way, my model bean stays in it's original condition until I go to save the form data, from something like a *Save *button click. That way, I don't have to worry about any external references to the same bean seeing the changes before I want them to. And with a *Cancel *button click I can just repopulate the form from the model object. The dirty field gets set back to false upon loading, saving, or cancelling. On Tuesday, January 29, 2013 4:26:29 PM UTC-5, BM wrote: I have a form in GWT and I want to capture an event similar to dirtyform flag in JQuery. Basically I want to understand if any of the form data has been changed. The requirement is pretty simple here. I am NOT looking for if the data has been actually been modified but just to find out if they touched my form data by any way. So let's say if my form has one GWT Textbox and one ListBox. For me the form data is changed with any of the following condition: 1) If the user changes the value inside Textbox and revert it back to previous original value. 2) The user changes the default selection of ListBox to new selection but changes back to default selection. 3) If the user changes the value inside Textbox to a new value. 4) The user changes the default selection of ListBox to new selection. The form data is not changed if the user just views the form but did not change any of the values in the Widgets at all. One way I thought would be to use onChange event and set a local flag hasDataChanged to true. Once the flag hasDataChanged has been set to true then don't reset it as it means the user touched the form. Based on the value of flag hasDataChanged show an alert message when navigating away from the page. But my problem is that if there are more GWT user interaction widgets (let's say 15 TextBox, 5 ListBox), the UI will fire onChanged Event every time. Plus I have to add onChange event handler to all of my GWT widgets. Perhaps there is a better way to do handle this. May be on view level if there is a single event I can assign which knows if any of GWT widgets been touched by the user?

Re: EditTextCell column fires update when clicked if using SiingleSelectionModel
Danilo,
That worked for me, although the line numbers were slightly different. I
edited code from 2.5.1 - was yours based on an earlier version?
I'm still trying to figure out the logic flow, given that the issue doesn't
occur until I add a selection model.
I like the selection cell concept. I've made a radio group cell to handle
a set of radio buttons, but the drawback has been that it takes up a lot of
space. Your concept layered on top of that might be a good solution,
especially if I can use a popup when the buttons are displayed. (General
thought - it seems like a generic popup cell might be useful, which things
like DatePickerCell could extend, but that would also give inherited logic
for any other sort of custom popup cell I'd want to create.)
On Sunday, August 25, 2013 12:25:33 PM UTC-4, Steve C wrote:
In a simple celltable, if I set a SingleSelectionModel, then clicking on
an EditTextCell triggers the updater for that column, even though the
editor doesn't even open (and the value is the current value). Without the

Is this expected behavior?
I've pasted sample code below.
Also worth noting is the behavior if I hit *Enter *to clear the alert box
- that triggers whatever enter would do on the cell (like open it for
editing). Better yet, try editing a cell, and clicking on a different row,
then using *Enter *to close all of the alerts that come up.
public class EditTextCellBug implements EntryPoint {
public void onModuleLoad() {
ListBean list = new ArrayListBean();
list.add(new Bean(John));
list.add(new Bean(Jane));
ListDataProviderBean provider = new ListDataProviderBean(list);
// problem occurs whether we use explicit key provider or not
CellTableBean ct = new CellTableBean(provider);
provider.addDataDisplay(ct);
ColumnBean, String col = new ColumnBean, String(new
EditTextCell()) {
@Override
public String getValue(Bean b) {
return b.name;
}
};
col.setFieldUpdater(new FieldUpdaterBean, String() {
@Override
public void update(int index, Bean b, String value) {
Window.alert(b.name + updating to + value);
b.name = value;
}
});
ct.addColumn(col);
// problem doesn't occur if we don't set the selection model
SingleSelectionModelBean selModel = new
SingleSelectionModelBean();
ct.setSelectionModel(selModel);
RootPanel.get().add(ct);
// doesn't fire updater - only manual selection does
selModel.setSelected(list.get(0), true);
}
}
class Bean {
public String name;
public Bean(String name) {
this.name = name;
}
}
As a side note, with the single selection model in place, it takes a
second click to open the cell for editing if the row wasn't currently
selected. (I think I may have a misunderstanding of the role of a selection
model, since it doesn't seem to be needed for simple editing, and there are
three states a row can have, no bg, yellow bg, and blue, using the default
styling. Do I only need one if I actually want to do something with the
user's selection?)

Re: use GwtCreateResource to provide text programatically
What you're asking for could be (in my humble opinion) useful. But, as
things currently stand, it won't work syntactically. The method in the
bundle doesn't return the resource, it returns an object that lets you
create the resource. So, if anything was going to work at all, it would be:
{res.labels.create.title}
Eclipse code-assistance actually suggests create after res.labels. - but
then flags the completed expression as an error.

My code looks like this already but res.label.title does not work. I
could try to first store a reference to res.labels.create but it seems
like I can't access any methods of labels in my uiBinder.
Is there a solution for me ? Maybe with a custom
ResourceGeneratorhttp://www.gwtproject.org/doc/latest/DevGuideClientBundle.html#Pluggable_Resource_Generation
? In this case some more pointers would be welcomed because i didn't
really catch how that worked...

Re: Correct way to sink events on UiBinder Element
Here's how I've done it for a click on a save button within a binder: I
don't have any call to sinkEvents - I think that's OK because the Widget
class does that already (?)
@UiField
ButtonElement saveButton;
// other UiFields
public HandlerRegistration addSaveHandler(final ClickHandler handler) {
return addDomHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
if (Element.as(event.getNativeEvent().getEventTarget()) ==
saveButton)
handler.onClick(event);
}
}, ClickEvent.getType());
}

Re: EditTextCell column fires update when clicked if using SiingleSelectionModel
I'vde been looking through the EditTextCell code, and can't figure out
where that happens. In onBrowserEvent it looks like the flow of execution
should end up in edit mode under the circumstances I described.
What patch did you make?

I was having a similar issue and made a simple patch to the EditTextCell
component in order to avoid always firing the update event. Now my
EditTextCell only fires when its value has really changed.

In a simple celltable, if I set a SingleSelectionModel, then clicking on
an EditTextCell triggers the updater for that column, even though the
editor doesn't even open (and the value is the current value). Without the
selection model this doesn't happen.
Is this expected behavior?
I've pasted sample code below.
Also worth noting is the behavior if I hit *Enter *to clear the alert
box - that triggers whatever enter would do on the cell (like open it for
editing). Better yet, try editing a cell, and clicking on a different row,
then using *Enter *to close all of the alerts that come up.
public class EditTextCellBug implements EntryPoint {
public void onModuleLoad() {
ListBean list = new ArrayListBean();
list.add(new Bean(John));
list.add(new Bean(Jane));
ListDataProviderBean provider = new
ListDataProviderBean(list);
// problem occurs whether we use explicit key provider or not
CellTableBean ct = new CellTableBean(provider);
provider.addDataDisplay(ct);
ColumnBean, String col = new ColumnBean, String(new
EditTextCell()) {
@Override
public String getValue(Bean b) {
return b.name;
}
};
col.setFieldUpdater(new FieldUpdaterBean, String() {
@Override
public void update(int index, Bean b, String value) {
Window.alert(b.name + updating to + value);
b.name = value;
}
});
ct.addColumn(col);
// problem doesn't occur if we don't set the selection model
SingleSelectionModelBean selModel = new
SingleSelectionModelBean();
ct.setSelectionModel(selModel);
RootPanel.get().add(ct);
// doesn't fire updater - only manual selection does
selModel.setSelected(list.get(0), true);
}
}
class Bean {
public String name;
public Bean(String name) {
this.name = name;
}
}
As a side note, with the single selection model in place, it takes a
second click to open the cell for editing if the row wasn't currently
selected. (I think I may have a misunderstanding of the role of a selection
model, since it doesn't seem to be needed for simple editing, and there are
three states a row can have, no bg, yellow bg, and blue, using the default
styling. Do I only need one if I actually want to do something with the
user's selection?)

Re: load image file from directory outside WAR folder and display in gwt app.
The solution for that would be no different fro GWT than for any other client-side approach: write a servlet that can locate the file and stream the image contents to the response output stream. The file path/name info can either be a parameter, or, with some clever servlet mapping, part of the url used to invoke the servlet. A search like servlet stream image yields a lot of possible approaches.

Thanks for asking that question - it led me to a solution to a problem
that I've had, which is skinning an app using different versions of
resources loaded asynchronously from the war directory as opposed to coded
into a ClientBundle.
I created a client bundle extending SimplePager.Resources, with sources
that reference dummy placeholder images in my source tree, then created a
separate class implementing that interface. In the constructor I populate
it from the GWT.created bundle (since some of the resources aren't dynamic,
and I can just delegate through to them) but then load my dynamic images
into Image widgets. Those, in turn, are each given to an implementation of
ImageResource that holds an Image widget, and obtains the width, height,
url, etc. from it (wasn't sure what the heck to do with getName, or how to
implement isAnimated). Those are the return values from the associated
methods in my resource object. And then I give that to the pager
constructor.
The asychronicity turned out to be a bear, since I'm using a LoadHandler
for each image to know when the size values will be available, and that
won't do anything unless I actually add the Image to the document, so I had
to create a hidden div to put them into. I haven't yet tested if that's
necessary with a data: url. And a lot of layout tasks had to be pushed off
into a callback.
The concept works, but I suspect that unless I make all versions of a
particular image the same size, I can't use any CssResource tricks based on
the image. That's probably not a big deal - since the variations generally
would all be the same size. Also, I don't think that there's any existing
Resource class in the API with CSS resources that depend on the images, so
it would only be an issue with custom resource classes.

Re: ClientBundle problem: The following unobfuscated classes were present in a strict CssResource:
Several places:
The CSS resource processor expects to obfuscate the class names from your
CSS file. So, for example, labels might get turned into GESPCACKI.
That's why you have a method declared in the interface, so you can retrieve
the obfuscated name string.
You don't explicitly see a method where you use labels in the Uibinder,
but the attribute {res.style.labels} in the tag g:Label
ui:field=labUsername addStyleNames={res.style.labels} is actually
invoking res.style().labels().
If you wish to use class names in the CSS file that you don't want
obfuscated (like .gwt-Label, for example), you need to mark them with
@external:
mycss.css :
@external .headerPan, .textb, .button;
.headerPan {
background-image:none;
background-color:blue !important;
height:40px;
border-bottom:1px solid black;
position : relative;
font-size:10.0 em;
}
etc.
In these lines:
headerPanel.addStyleName(headerPan);
labPassword.addStyleName(labels);
username.addStyleName(textb);
validBtn.addStyleName(button);
The styles for headerPan, textb, and button will work as expected. The
statement
labPassword.addStyleName(labels);
Will do nothing, since there is no class named labels in the CSS. It
should be
labPassword.addStyleName(res.style().labels());
And, somewhere before that you need to create res and inject the stylesheet:
example.resources.Resources res =
GWT.create(example.resources.Resources.class);
res.style().ensureInjected();

Re: Correct way to sink events on UiBinder Element
It sounds like you're using an HTML-based binder, not a Widget binder, so
your createAndBindUi would produce an Element that your class can set as
its DOM representation (I usually make my class extend Element - for some
reason the Eclipse wizard wants to make it a UiObject). And, then, as
another poster mentioned, you can have SpanElement, DivElement, etc., in
the Java class to match what's in the xml. So, you shouldn't have to cast
to element, the pieces should already be some sort of Element.
I'm pretty sure @UiHandler won't work for an HTML-based binder, since the
Java fields aren't widgets.
I haven't tried your approach for hooking up handlers, but have used a
delegating approach - the Java class, as a Widget, can have a regular click
handler, which can then look at the target of the event and decide what to
do accordingly (like fire off a custom event that represents whatever
clicking the element meant).

Typed service methods using RequestFactory and ServiceLocator
I'm trying to work up an example of request factory using a service
locator. The discussions/tutorials all say that ServiceLocator is useful
when there's a generic DAO with static methods for instance operations. I'm
taking that to mean that my entity classes don't have their own methods to
get a specific instance.
The javadocs for ServiceLocator say A ServiceLocator provides instances of
a type specified by a
Servicehttp://www.gwtproject.org/javadoc/latest/com/google/web/bindery/requestfactory/shared/Service.htmlwhen
Requesthttp://www.gwtproject.org/javadoc/latest/com/google/web/bindery/requestfactory/shared/Request.htmlmethods
declared in a
RequestContexthttp://www.gwtproject.org/javadoc/latest/com/google/web/bindery/requestfactory/shared/RequestContext.htmlare
mapped onto instance (non-static) methods. I think that's actually
backwards -- it looks like the ServiceLocator supplies an instance when
what would normally be instance methods (like persist) are actually static
and passed an instance. My guess is that the framework generates glue code
to invoke the methods on the instance but also pass them the instance.
My entities are all instances of DataStoreItem. One specific subclass is
Flick.
I can write a service that uses a locator with static methods including
public static DataStoreItem find(Class? extends DataStoreItem clazz, Long
id).
My request context class is public interface FlickRequest extends
RequestContext.
And, unlike so many of the examples I've seen, I actually see benefit to
having the context definition include a method to retrieve a single
instance (otherwise, how do I actually request one?):
public RequestFlickProxy get(long id);
But, as I said before, my Flick class doesn't include a static get method.
The locator analog to that method takes a class object in addition to the
id (to be honest, I haven't tried passing it my proxy class object, but I
doubt that would work, since on the server side it would have to receive
the actual bean class, not the proxy class). And, it looks like the
ServiceLocator will only work for the methods that ought to operate on
instances, not methods that would always be static.
I tried this as my service locator:
public class FlickServiceLocator implements ServiceLocator {
@Override
public Object getInstance(Class? clazz) {
return new ItemDAOWrapperFlick(Flick.class);
}
}
Where the ItemDAOWrapper holds the class object and delegates find(id) to
find(clazz, id), but am still seeing errors on my request context that my
domain class doesn't have a find method.
So, how do I write a method to get an instance by id, when the entity class
doesn't do that, and my generic DAO class can only do that when given an
class to work on (short of writing an explicit wrapper class for each
domain type that can add those methods)?

Re: Dom change propagation time
I've run into similar issues adding a style name to a widget and then immediately trying to read the class attribute of the element. I think that the issue is that while JS is single-threaded, the browser itself isn't required to be, and the effect of some JS statements can take time to complete within the browser's native code, even though the JS method returned immediately. Try Scheduler.scheduleDeferred, which runs your code with a minimal timeout (basically what you did yourself -- your code should also work if you make the timeout just 1 millisecond).

StyleInjector issues in IE
I'm using Ajax to retrieve multiple CSS files, each dedicated to a single
media query. or each one, I then wrap the appropriate media query around
the contents, and then inject it via StyleInjector.injectAtEnd.
The page the app is running has a whole pile of stuff going on, including
scripts related to social network sharing.
We've run into two issues:
1. The media queries don't seem to be applied, although IE9-10's dev tools
are hinky enough that this may not actually be the problem
2. Image urls in the CSS sometimes get applied as if they came from some
other domain, in this particular case, one of the social media ones.
I believe that the issue is in StyleInjector.StyleInjectorImplIE, at the
end:
@Override
public StyleElement injectStyleSheetAtEnd(String contents) {
int documentStyleCount = getDocumentStyleCount();
if (documentStyleCount == 0) {
return createNewStyleSheet(contents);
}
return appendToStyleSheet(documentStyleCount - 1, contents, true);
}
Where the style element it chooses to add to is likely to be one of the
foreign ones, especially since the social media scripts tend to run late in
the load process. It looks like IE exposes the href of the CSS, so this
could be checked.
So, I'm going to try changing it to use injectStylesheet, which looks like
it chooses the shortest to add to if there are already 30 in place (but
isn't that going to affect ordering of the rules?)
I would try to write an extension of StyleInjectorImplIE, except that, like
many GWT classes, it isn't extensible. I've finally gotten annoyed enough
at that to write a separate post about it.

GWT classes aren't extensible
On many occasions, I've wanted to adjust the behavior of a GWT class, but have found that I can't, because they tend not to be written with extensibility in mind. 1. Many internal utility methods are private 2. Many inner classes are private, or maybe package access For example, I wanted to make just a few tweaks in StyleInjector. But, any helper logic that I might want to use from the base, such as private native StyleElement createElement() or private StyleElement createNewStyleSheet(String contents), are, um, PRIVATE. So I basically have to copy the entire code for the class in my extension. Similarly, when I wanted to create a nullable EditTextCell, I couldn't just extend that class, since the actual data for the cell in is static class ViewData, which I can't get to, because I'm in a different package. So, I had to copy the entire class in order to change just a few lines.

I see your point, but, on the other hand, I worry about something that needed to be fixed in one of those methods or inner classes that I copied, and would probably never know about. On Friday, July 12, 2013 7:05:04 PM UTC-4, Ed wrote: This is a known issue with gwt, see the issue tracker for details. However, don't forget that this gives the GWT dev team the possibility to change the internal behavior of classes as they don't have to worry about breaking changes because they are extended... So it makes it easier for the dev team to move on adding/changing features. On the other hand, copying a class and adding your own stuff isn't that much work ;) But still, I have to admit, that things could be set up a bit more OO such that improves extendibility. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Anchor does not work in IE - very strange problem!
I've found that with the IE developer tools, you need to refresh the DOM view within the tools (there's a refresh icon in the HTML view section). The view doesn't seem to take the JS changes to the page into account initially. (And sometimes you never see CSS that GWT injects, but that's off-topic.) BTW, I ran your code and it worked fine in IE-7-10 as provided by the dev tools in IE10 (I just had onCommand do an alert with the two values), so maybe the issue is further down the line.

Re: How to change css style during runtime?
Rather than setting the primary name, you could create a new style that
modifies the property, and add or remove that name. I'm assuming below
that cellTableKeyboardSelectedCell is for that purpose, so you could do
widget.addStyleName(cellTableKeyboardSelectedCell). If so, I'd make the
rule .cellTable.cellTableKeyboardSelectedCell.
Even better would be to use a dependent style:
.cellTable.cellTable-keyboardSelectedCell {
border:
}
and then in your Java code:
widget.addStyleDependentName(keyboardSelectedCell);
or, to remove it:
widget.removeStyleDependentName(keyboardSelectedCell);

How can I access my css file during runtime and change that specific

Probably it has to do with cellTable.setStylePrimaryName(), but I could

CSSResource processing of CSS files in war directory
I'm working on an app where we decided to create CSS resources under the source tree as usual, but only setting properties that affect layout, like display, float, sizing, positioning, etc. The look of the app is under control of design-oriented folks that aren't GWT-savvy, who want to be able to adjust things like colors, backgrounds, etc., without having to recompile and retest. Their CSS files are located in the war directory. Currently, our source-tree-based CSS uses all @external class names, and we then pull in the war-based CSS files via RequestBuilder, and inject them into the app. I've provided the design folks with a list of the class names that we apply in the GWT code, and a map of where they are used, so that they can set their colors, etc. I think that there might be a way to use the compiled CSSResource artifacts on the server side, by requesting a servlet instead of a plain CSS file, and then processing the CSS files the way the compiler does, but at runtime. That way I can use class name obfuscation, and all the nice things like @def and @eval. (I might end up using a servlet or JSP anyway, in order to ensure that the war CSS files don't try to set certain properties, but it would be nice if I could also use the resource processing logic.) But, before I venture down that road, I figured I'd see if that is indeed possible, and if anyone has tried that, or has found an alternative way to defer the CSS until runtime. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: reordering of column in celltable
I tried this, and it works, with two issues:
1. you need to remove the existing instance of the column. Unlike regular
DOM elements (and therefore Widgets), which can only be in one place at a
time, the cells generate a rendered string, which will be a new snippet of
HTML, which will be result in new DOM element. And, apparently, nothing
the table logic is policing the number of times a given column can appear,
so the column will exist in two locations: the original location pushed one
to the right if the insert position was before it, and the new location.
2. With a DatePickerCell, the first time I changed the date via the
popup, nothing happened in the table, but the column updater did get
invoked, and refreshing the document, or just paging forward and back
again, showed me that the update had taken, and I saw the new data.
Subsequent edits to cells in that column did reflect immediately in the
table.
Code snippet:
private CellTableCustomer ct = new CellTableCustomer(pageRows);
// later, as the last column in the table:
ColumnCustomer, Date expiresColumn =
new ColumnCustomer, Date(
new DatePickerCell(DateTimeFormat.getMediumDateFormat())) {
@Override
public Date getValue(Customer cust) {
return cust.getExpiration();
}
};
expiresColumn.setFieldUpdater(new FieldUpdaterCustomer, Date() {
@Override
public void update(int index, Customer cust, Date value) {
cust.setExpiration(value);
custUpdater.updateCustomer(cust);
}
});
TextHeader expiresHeader = new TextHeader(Expiration);
ct.addColumn(expiresColumn, expiresHeader);
// after finishing table setup, and adding everything to the Root Panel
int colIndex = ct.getColumnIndex(expiresColumn);
ColumnCustomer, ? col = ct.getColumn(colIndex);
ct.removeColumn(expiresColumn);
ct.insertColumn(0, col, expiresHeader);

Gin module binding using annotatedWith and AsyncProvider
If I want to inject an instance of a specific class based on an annotation,
I can do this in a Gin module:
bind(DiSecondary.class).annotatedWith(Special.class).to(DiSecondarySpecialImpl.class);
I also already have:
bind(DiSecondary.class).to(DiSecondaryImpl.class);
I can then retrieve the special instance into my DiMain (Composite wrapping
a Panel) constructor with:
@Inject
public DiMain(@Special DiSecondary special) {
add(special);
}
But, if I want to code-split DiSecondarySpecialImpl using AsyncProvider,
the analogous approach does not work:
@Inject
public DiMainAsync(@Special final AsyncProviderDiSecondary
diSecondaryProvider) {
diSecondaryProvider.get(new AsyncCallbackDiSecondary() {
public void onFailure(Throwable caught) {}
public void onSuccess(DiSecondary result) {
add(result);
}
});
}
I get a GWT compiler error. If I remove the annotation, then, of course, I
get the non-special implementation.
Am I being unreasonable to expect that the compiler could apply the
annotation to the async provider for the base class instead of the base
class itself?
Is there a different route that I can use to get the desired behavior
(annotation-based selection of an alternate async loaded class)?

Adding event handlers to elements in HTML-style UiBinder
I finally managed to find a way to do this, but am in no way sure if I
haven't left a problem lurking somewhere underneath.
I had a table containing form elements that I wanted to use as a
UiBinder template. I didn't need event handling for most inputs, but
did want a click handler for a button. I tried Button.wrap, but it
looks like that only works for a button not already owned by a widget,
but my table binder becomes a widget, so that route was out.
It would be nice if there was some built-in way to widgetize an
element like that, so that from that point on normal GWT tasks could
be performed on it.
I used an HTML binder rather than a Widget binder because there was no
way I could have a table as the top-level element without using a tag
like g:Grid, which I wanted to avoid because then I can't edit the
layout easily, and also because I already have the table code. (One
goal of this was to take a number of existing JSP tag files and turn
them into GWT widgets via the binder. Other than the event issue,
that actually works out very well.)
Wrapping my table in something like a g:HtmlPanel, where I could use
a g:Button was out, since then the container div is the element that
my primary style affects, and setting its width allowed the table to
overflow the boundaries.
So, here is the line from my template:
trtd colspan=2button ui:field=saveButtonSave/button/td/
tr
And, in the java file, my registration method:
public HandlerRegistration addSaveHandler(final ClickHandler handler)
{
return addDomHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
if (Element.as(event.getNativeEvent().getEventTarget())
==
saveButton)
handler.onClick(event);
}
}, ClickEvent.getType());
}
So, have I done everything that I need to to make this work reliably?

One would think that the following should remove the focus border around a tab: TabBar bar = new TabBar(); // populate bar.getTab(0).setFocus(false); Yet a tab behaves as if it is focusable. I think this is because it COULD be Focusable, a FocusWidget, or a FocusPanel, but in the existing implementation it instead has a wrapper that is a FocusPanel, but the wrapper isn't what is returned by getTab. And, although the docs for the unrelated TabBar.onKeyPress method mention that one should add the handler to the individual tab wrappers instead, afaik there is no way to actually retrieve the wrapper. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: GWT appears to be overriding my css
If you use a stylesheet linked in from your html code, it will get
loaded before the theme stylesheet is loaded, so your styles will get
overwritten. If you put the stylesheet and associated images in a
public folder of your module and reference it in the gwt.xml file (a
la GWT 1.5), it will be added after the theme stylesheet, and thus
override the GWT theme styling.
Another approach is to make your styles more specific than the GWT
styles, for example, html body .gwtDecoratorPanel .topLeft { ... }.
This seems to work in IE7 and FF 3.5. I have seen rules starting with
htmlbody in various posts, but this does not work in IE for me. My
dissatisfaction with this is that I can see a browser deciding that
the html body doesn't add any specificity to the rule, since that
combination is guaranteed to happen.
Yet another approach is to rely on the implementation of a widget,
with a rule like .gwtDecoratorPanel tr td.topLeft { ... } The problem
with this is that conceivably some day GWT could decide that
positioned divs are better than a table for the DecoratorPanel
implementation.
Perhaps the best approach would be to give the body an id, or use an
id'd div as the RootPanel, and start the css rule with the id.

Hi,

At this point (besides the root panel) all I've added is a single

image for the background in a body tag. In hosted mode, it all
displays correctly. However, when I click on compile in the hosted

From the browser, I checked to make sure the link to my custom sheet
was good and I also used the link in the style sheet to make sure I
could see the background image. Also, just for grins, I commented out
the body tag in the standard.cssthat GWT provides. Not only did that
not make a difference, the act of compiling replaced the standard.css
file, thus effectively uncommenting the body tag. And finally, I
tried adding the body tag to the defaultcssfile in the WEB-INF

is being overridden behind the scenes. That doesn't make a
lot of sense, but that's what it looks like.

Creating a module in GWT 1.7 - css file location

Most of the examples out there are repackagings of the same simplistic ones that have been around for a few versions now. In addition to the undocumented item listed in the previous comment, it seems that your test class must be in the same package as your entry-point class, but sourced from the test folder instead of src. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Creating a module in GWT 1.7 - css file location
OK, I answered my own question, at least as far as item #1, with some help from http://code.google.com/webtoolkit/doc/1.6/DevGuideOrganizingProjects.html#DevGuideAutomaticResourceInclusion It seems that either approach will work. Having the css in the public package will result in it automatically being included, as long as the modules gwt.xml file references it. Otherwise, I need to include the module's css file in the war directory of the inheriting project, and have that project's html file link to it. I guess that would also give me the ability to more easily override the styling, plus it gets around Eclipse's reluctance to create a package level named public (although it was nice enough to use it if I created it externally). I still wonder about #2 - if there is a way to jar it without resorting to two command-line jar commands ...

I haven't tested to see if the public package concept still works. If I wanted to have a project as a module, I could then jar the whole thing, and the project inheriting the module would find the css file in the public directory. 1. To create a module for 1.7, do I have to add the relevant css file to the new project's war directory, or do I back up and create it in a public package a la 1.5? (or do I do something else, like add the war directory to the module's jar file)? 2. Is there a tool in the Eclipse plugin to create/export a module jar file, or do I have to do that manually? 3. Is there a structure for the module war file other than that the root starts the package structure (e.g., a src folder, a bin or classes folder, etc.)? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Differences between Hosted and Web mode JUnit testing
I have read numerous times that Hosted mode tests bytecode, while Web
mode tests in actual JavaScript. Wanting to delve into this deeper,
I came up with the following, in which the JUnit tests succeed in both
hosted and web modes. I was expecting that because I used native JS
features not available in Java, it would fail in hosted mode:
package com.x.gwt.firsttest.client;
public class StringProducer {
public native String getSomeText()/*-{
String.prototype.yo = function() {
return Hello there;
};
return Yo.yo();
}-*/;
}
And then the test class:
package com.x.gwt.firsttest.client;
import com.google.gwt.junit.client.GWTTestCase;
public class FirstTest extends GWTTestCase {
public String getModuleName() {
return com.x.gwt.firsttest.FirstApp;
}
public void testStringProducer() {
assertEquals(Hello there, new StringProducer().getSomeText());
}
}

Event Handlers and event capture
Apparently Event Handling uses bubbling, not capture, since an HTMLPanel does not notice blur events on a contained input element (I believe that the blur event is fired through the capture phase by browsers, but does not buibble back up). Is there any way to capture BlurEvents in a HTMLPanel for a contained input element? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Getting reference to Widget from contained Element's id
If I have the id of an Element that I got using Widget.getElement (then I called setId on that), can I later use the id to get the Element and back up to its Widget? I'm using JSNI with library code that wants the id of an element to control. I'm passing the id into a JSNI function, but also want to affect the element in additional ways. But, in the JSNI function, I don't have access to the Widget. I figured I could call a regular method (which would have access to Widgets) from the JSNI method, but all I have to pass to it is the id. Hence my desire to look up the Widget from the Element's id. I guess I could make up my own Map of ids to Widgets, but was hoping something like that already existed. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Using exterrnal class in GWT and No source is available error
I'd like to use some external libraries in GWT for the server code, but get the error mentioned above. I took a look at the page at http://code.google.com/intl/fr/webtoolkit/articles/using_gwt_with_hibernate.html, which seems to do just that, and even downloaded the code zip file. But, I haven't been able t figure out how they get it to compile. There certainly doesn't seem to be any Hibernate source code involved Is there some sort of compiler flag to set, or other way to tell GWT to not peruse the source code? It seems that the GWT compiler ought to be able to figure out what classes it needs to look at and which it doesn't (presumably the only ones it needs to look at are those being serialized, and the servlets that are going to provide them - but for the latter group only to see what is being serialized, and not the other details of how those objects get populated). --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Migration Instructions 1.5 to 1.6 rename-to
The page at http://code.google.com/webtoolkit/doc/1.6/ReleaseNotes_1_6.html is somewhat unclear regarding rename-to: module rename-to='testapp' Which left me wondering: is the value arbitrary, and, how does it relate to any other settings or directories? (Since the file tree shown under that doesn't have a testapp directory, but does have TestApp). I followed the example, and made it the all-lowercase version of my project name, and noticed that it replaced the last part of the package structure (i.e., what had been an uppercase first letter was now a lowercase letter as in the rename-to value.) Doing this in Eclipse, I then had a testapp directory under war, but I assume that the graphic shown is prior to that occurring. But it might clarify what happens with the rename-to value to show that. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
