Re: problem with character encoding
thx for your investigation,
i'll try it with chnaged encoding of propery-file (at the moment i
load it via Properties.load.getresourceasstream(file)). but is there a
way to let my code let the reencoding, so that properties-file could
be utf-8?
('til now i thought that all java encoding is utf-x by default :-|)

Re: IE8-like tabs using GWT
Hi Bhavin- I'm not sure what an IE8-tab is. Do you just mean a tabbed interface? If so, you'll probably just need to check out the TabPanel: http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/user/client/ui/TabPanel.html Putting the tabs a the bottom is going to be trickier. Web pages are pages, not panels, so typically panel heights don't work so well. You might be able to specify a height and then have your content scroll within the panel. You're adding a lot of extra work for yourself, though. Good luck!

Re: GWT communicate with Tomcat
Hi Bastian- Your questions lead me to believe that you don't fully understand what GWT is or does. The GWT simply rewrites java code into java script. This is entirely a client thing that has nothing to do with a server. Now, there is also GWT RPC, which allows this rewritten (or translated) javascript to make asynchronous calls to a server. This is typically done with a java server and Tomcat will work just fine. As someone else said, once you are in the Tomcat environment you can do whatever you want. Good luck!

Re: Feedback on different backends for GWT
I use servlets because of their ease of use with GWT RPC. Maybe GWT RPC integrates with python nicely now (without needing to use JSON)? I really don't know, I haven't tried it. As for servlets, just like everything else in java, it's only as complicated as you make it. If you don't need struts and spring then why include it? Just create servlets and package a war file and deploy and be done with it. On Mar 22, 3:30 am, Uemit uemit.se...@gmail.com wrote: Hi everyone. I have to re-design an existing application which uses Pylons (Python) on the backend and GWT on the frontend. In the course of this re-design I can also change the backend system. I tried to read up on the advantages and disadvantages of various backend systems (Java, Python, etc) but I would be thankful for some feedback from the community. *Existing application:* The existing application was developed with GWT 1.5 (runs now on 2.1) and is a multi-host-page setup. The Pylons MVC framework defines a set of controllers/host pages in which GWT widgets are embedded (classical website). Data is stored in a MySQL database and accessed by the backend with SQLAlchemy/Elixir. Server/client communication is done with the RequestBuilder (JSON). The application is not a typical business like application with complex CRUD functionality (transactions, locking, etc) or sophisticated permission system (tough a simple ACL is required). The application is used for visualization (charts, tables) of scientific data. The client interface is primarily used to display data in read-only mode. There might be some CRUD functionality but it's not the main aspect of the app. Only a subset of the scientific data is going to be transfered to the client interface but this subset is generated out of large datasets. The existing backend uses numpy/scipy to read data from db/files, create matrices and filter them. The numbers of users accessing or using the app is relatively small, but the burden on the backend for each user/request is pretty high because it has to read and filter large datasets. The analysis of the existing backend (python) showed that because of python's GIL, concurrent heavy requests don't scale that well (cherrypy uses workers/processed for concurrent requests). Numpy/Scipy libraries however work well with matrices and arrays (filtering, sorting, etc). *Requirements on the new system:* I want to move away from the multi-host-page setup to the MVP architecture (one single host page). So the backend only serves one host page and acts as data source for AJAX calls. Data will be still stored in a relational database (PostgreSQL instead of MySQL). There will be a simple ACL (defines who can see what kind of data) and maybe some CRUD functionality (but it's not a priority). The size of the datasets is going to increase so the burden on the backend is probably going to be higher. There won't be many concurrent requests but the few ones have to be handled by the backend quickly. Hardware (RAM and CPU) for the backend server is not an issue. *Possible backend solutions:* *Python (SQLAlchemy, Pylons or Django):* *Advantages: * - Rapid prototyping. - Re-Use of parts of the existing application - Numpy/Scipy for handling large datasets. *Disadvantages:* - Weakly typed language - debugging can be painful - Server/Client communication (JSON parsing or using 3rd party libraries). - Python GIL - scaling with concurrent requests - Server language (python) client language (java) *Java (Hibernate/JPA, Spring, etc)* *Advantages: * - One language for both client and server (Java) - Easier to debug. - Server/Client communication (RequestFactory, RPC) easer to implement. - Performance, multi-threading, etc - Object graph can be transfered (RequestFactory). - CRUD easy to implement - Multitear architecture (features) *Disadvantages: * - Multitear architecture (complexity,requires a lot of configuration) - Handling of arrays/matrices (not sure if there is a pendant to numpy/scipy in java). - Not all features of the Java web application layers/frameworks used (overkill?). I didn't mention any other backend systems (RoR, etc) because I think these two systems are the most viable ones for my use case. To be honest I am not new to Java but relatively new to Java web application frameworks. I know my way around Pylons though in the new setup not much of the Pylons features (MVC, templates) will be used because it probably only serves as AJAX backend. If I go with a Java backend I have to decide whether to do a RESTful service (and clearly separate client from server) or use RequestFactory (tighter coupling). There is no specific requirement for RESTfulness. In case of a Python backend I would probably go with a RESTful backend (as I have to take care of client/server communication anyways).

Catching Key event in popup
I've got a GWT app with a login step.
user enter its login/pass then press enter or login button to perform
login action.
If login is invalid a popup signals an error.
I want to be able to close the popup when user press ok button or when
he hits Esc or Enter.
I've added a onPreviewNativeEvent method to catch the event
public void onPreviewNativeEvent (NativePreviewEvent event) {
int keyCode = event.getNativeEvent().getKeyCode();
if ((KeyCodes.KEY_ENTER == keyCode) || (KeyCodes.KEY_ESCAPE ==
keyCode)){
btnOk.click();
}
}
It is working fine but the Enter Key is not totaly catched so once the
popup is closed the Ok button (for login action) is also triggered so
an other popup is open.
I try to consume or cancel the event calling event.consume(); or
event.cancel(); but I don't see any effect.
1th question what are the effect of
- consume and cancel ?
2nd question how can I definitivelly cancel an event to be sure that
no other component will handle it ?

Now this have been corrected, we have an answer which is 405 or 500 depending on how we construct the CURL or WGET request. So we still need to understand what is wrong.

Actually we are not able to debug it because the are no logs in our log4j or in tomcat logs signalling that there is something wrong. More over we have this problem at a frequency than less 1 per month and only in production environnement so it is not easy to find the reason. Next time I will ty a kill -3 on the tomcat to look if there is some blocked threads.

Re: GWT communicate with Tomcat
Hi there :) , as already explained, the GWT-Compiler converts the java code into java-script code. Everything you implemented in the XX.XX.client package will be transformed into java-script (by the gwt-compiler). Everything you implemented in the XX.XX.server package will work on the server (tomcat) without transformation into java-script. The easiest way to communicate with the server ist over the gwt-rpc protocol. There are many tutorials how to implement such a communication - (imo) its really easy. But you dont need to use the gwt-rpc protocol. You can also use the servlet-technology. F.e. to upload data u have to use the servlet-technology, because the gwt-rpc protocol doesnt support data uploads. A big advantage of the gwt-rpc protocol is that you can exchange objects between client and server (without any transformation into json or any other format) - GWT handle the exchange for you. You only have to implement the IsSerializable-Interface (The class have to lie in the XX.XX.client.XX. package). Try it out, GWT is a nice Framework and easy to understand (if you realized the difference between client/server code).

Hosted Server crashes instantly
Hi, I have an extremely annoying issue with running hosted mode from Eclipse. Since about two weeks ago the development server will start up, just to terminate as soon as its finished startup - without any errors. Worse yet I have no idea what could have caused it, since the timing of the start of the problem doesn't coincide with any major changes I made. Weirdly it does work very rarely but I can't reproduce how to get it to work and when it does work, if I terminate the server and attempt to start it up again, chances are it won't work. I have tried the following: -Changing the AppEngine GWT version - doesn't work -Using a different Eclipse version on the same machine - doesn't work -Running the server on a different port - doesn't work -Running a different GWT project on the same machine - doesn't work -Checking out the project again on the same machine - doesn't work -Running the project on a different machine from an SVN checkout - works -Running the project on a Windows XP virtual machine into which I copied the eclipse workspace that didn't work (and fixed the classpath etc.) - works So the problem persists on one machine, regardless of the Eclipse version, GWT/Appengine version gand project. The only thing that I can think of at the moment is that my Java installation is somehow broken, although that seems very unlikely (Eclipse works fine) and also doesn't really explain the absence of an error message.

Re: ORM or JDBC?
I've found using ORM in GWT to be pretty much the same as using it in any other setting. If you like it, go for it. I personally do not care for it, as I've found, at least in the projects I've worked on, that the added complexity doesn't seem to pay off. I'd rather just write a thin DAO layer and be done with it. Toplink has been my only real experience with such things, however, so perhaps I just got stuck with a crappy ORM. -Ben On Mar 23, 3:45 am, csaffi csaff...@gmail.com wrote: Hi everybody, I would like your opinion regarding the use of ORM in web applications built with GWT.

Weirdly it does work very rarely but I can't reproduce how to get it to work and when it does work, if I terminate the server and attempt to start it up again, chances are it won't work. I have tried the following: -Changing the AppEngine GWT version - doesn't work -Using a different Eclipse version on the same machine - doesn't work -Running the server on a different port - doesn't work -Running a different GWT project on the same machine - doesn't work -Checking out the project again on the same machine - doesn't work -Running the project on a different machine from an SVN checkout - works -Running the project on a Windows XP virtual machine into which I copied the eclipse workspace that didn't work (and fixed the classpath etc.) - works So the problem persists on one machine, regardless of the Eclipse version, GWT/Appengine version gand project. The only thing that I can think of at the moment is that my Java installation is somehow broken, although that seems very unlikely (Eclipse works fine) and also doesn't really explain the absence of an error message.

How to troubleshoot NPE during UIBinder component initialization
Having the NPE problem during view initialization I determined that
this element
@UiField(provided=true)
ShortMessageBox shortMessageBox;
causes it. When I remove it from the view everything works fine.
The ShortMessageBox is defined UIBinder-based componet:
public class ShortMessageBox extends Composite {
public interface ShortMessageBoxUiBinder extends UiBinderWidget,
ShortMessageBox {
}
@Inject
public ShortMessageBox(final ShortMessageBoxUiBinder
uiBinder) {
super();
initWidget(uiBinder.createAndBindUi(this));
clearMessageWidget();
}
}
As you can see I am using gin but I have other similarly defined
components that work just fine. Since I am not looking for solution
with this question I don't provide all supporting code.
The question is how to troubleshoot/debug UIBinder views and
components when the following exception encountered during
initialization:
Caused by: java.lang.NullPointerException
at
com.myapp.client.ui.ShortMessageBox_ShortMessageBoxUiBinderImpl.createAndBindUi(ShortMessageBox_ShortMessageBoxUiBinderImpl.java:

1058)
My problem is that something obviously going wrong during
ShortMessageBox initialization but no detailed information or ways to
debug it that I know of...

Using java.lang.reflect or similar

Tag for page encoding
Hello, I have a GWT (2.2) application making use of GWT-RPC. It is working fine, but there is a problem when accessed through a proxy. Besides the proxy issues mentioned in other discusions in this forum (which has been taken into consideration), the proxy blocks responses from the application server which contain the element meta charset=UTF-8 / This element appears in some GWT generated files with names like hashvalue.cache.html but does not appear in the host page, for example, where the encoding is specified by the element meta http-equiv=Content-Type content=text/html; charset=utf-8 Now, after replacing manually the first element (meta charset=UTF-8 /, standard of HTML 5 only) with the second (meta http-equiv=Content-Type content=text/html; charset=utf-8) in all the hashvalue.cache.html files, the application works smoothly even when accessed through the proxy. As the configuration of the proxy is not under my control, I would like to know if there is any compiler switch to achieve what I have manually done (or if you have any other solution, for the matter).

Re: Using java.lang.reflect or similar
You can create an interface like this
interface PropertyT { String get(T dto); }
initialize a MapMyDTO, String for each DTO type
myDtoMap.put(getFilename, new Property() { String get(MyDTO dto) { return
dto.getFilename(); } });
...
and then call
myDtoMap.get(propertyString).get(dto);
to get the property value.
But if you need this feature to display columns in a table, CellTable has
Column class that works similarly.

Re: Celltable column header overlap / bug?
Just an update. I think the problem I am seeing has more to do with a bug regarding column header display for a celltable than it does sorting. If I remove all sorting logic from my celltable, I can still get overlapping double image column headers if the data being mapped into the table does not line up with initial placement of column headers before any action is taken that populates the table with data. If columns from the initial empty table need to shift to make room for data, the original column text appears underneath the newly placed column text. As it stands now, even if I carefully control column widths so no shifting is needed, I still get a double image when sorting for the column header of the column being sorted. Controlling the widths so no shift is needed does remove the double image problem when data is mapped into the table, though. Is there a work-around until a fix is released? I notice a commit from October to CellTable that has to do with redrawing headers, that may be the fix to this bug. thanks! On Mar 22, 5:22 pm, Jim Weaver weaver...@gmail.com wrote: Hi, I am new to GWT, and have an issue with column headers on a celltable with GWT 2.2. Several of the columns are sortable, and when I click on the header to sort them, I see a double image on the header text of the sortable column, and also the little graphic that indicates the sort arrow (down or up arrow) overwrites on top of the previous one, so I get an hour-glass looking thing. The columns involved do sort properly. It's not a functional problem. It seems like it is trying to calculate where it should render the column headers and the little sort icon after I click on a sortable column, and is calculating a little bit off and not quite replacing where the previous text was rendered, so you get a fuzzy overlapped effect. Has anyone else seen this? I am using fixed width columns: table.setColumnWidth(col1, 7.00, Unit.PCT); table.setColumnWidth(col2, 7.00, Unit.PCT); table.setColumnWidth(col3, 10.0, Unit.PCT); table.setColumnWidth(col4, 10.0, Unit.PCT); table.setColumnWidth(col5, 10.00, Unit.PCT); table.setColumnWidth(col6, 10.00, Unit.PCT); table.setColumnWidth(col7, 16.00, Unit.PCT); table.setColumnWidth(col8, 10.00, Unit.PCT); table.setColumnWidth(col9, 15.0, Unit.PCT); table.setColumnWidth(col10, 5.0, Unit.PCT); The number of columns that are sortable does not seem to affect this problem. Even with just one column sortable I get some weirdness. Ah, there is one other oddity that could be related. When I make multiple columns sortable, the little sort graphic only shows up on one of them. The columns that are sortable all sort when I click the header, but only one of the columns will show the little arrow graphic beside the header text. Is there an example project that has multiple sortable columns on a cell table? I'm sure it's something I'm doing wrong. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Working with third party client libraries in gwt
If you want to use them on the client side, you must have the source code for GWT to translate to JS. In addition, this code must be compatible with GWT's subset of Java. Using third party jars on the server side, on the other hand, is just straight Java. I would hazard a guess that your issue is due to an attempt to use them on the client. -Ben On Mar 23, 8:27 am, Prashant er.prashants...@gmail.com wrote: Hi Guys, I'm very new to GWT and have basic experience in web development.

Re: Feedback on different backends for GWT
It sounds like much of your performance is issues will probably be more database related than anything, so a lot of the other backend decision probably come down to personal preference or experience. I've been working on a GWT project that talks to a Django/MySQL backend for several months. The RPC is all JSON, which requires a bit of marshalling logic on each end, but so far it's not been a maintenance problem (the data model is fairly stable). If you're worried about Python's GIL for concurrent web requests, I don't think that's an issue because you're going to be running different instances of the runtime (each with their own GIL) for parallel web requests. Apart from a personal preference for Python's syntactic economy, I found I could get my head around Django's ORM, session management and other back-end functionality very quickly. Not wanting to rebuild all of this (or relearn in a new framework) is primarily what drove the Django selection. The Java servlet path may just be suffering from a wealth of options, but it felt like a lot more mental effort to put the appropriate platform together. Which probably just means I'm lazy. It's the devil you know... I'm sure somebody with more depth of experience on the various Java server side frameworks would come to different conclusions. As rjcarr points out, GWT-RPC makes a compelling case for going that route especially with the tools evolving more and more. The downsides you've pointed out are definitely there... You're switching between languages all day (forgetting semicolons in Java and putting extraneous ones into the Python), and you catch a lot more runtime issues that a strongly-typed language would have been caught at compile time, but still nothing FireBug and Django's debug responses don't highlight well. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Styling Cell individually in CellTable
Hi,
I've got a use case with the CellTable where a cell should be rendered with
a different background color depending on the cell content. I've also some
TD with a rowspan 1.
I've implemented an AbstractCell to set a style depending on the status
(short version) :
public class StatusCell extends AbstractCellStatus {
@Override
public void render(final Status status, final Object key, final
SafeHtmlBuilder sb) {
String cellStyle;
if (status == Status.OK) {
cellStyle = greenCell;
} else {
cellStyle = redCell;
}
sb.appendHtmlConstant(div class=\ + cellStyle + \);
sb.appendEscaped(status.toString());
sb.appendHtmlConstant(/div);
}
}
Here is the result :
table class=cellTableWidget GA3XJ-DDEM
thead
tr
th class=cellTableHeader GA3XJ-DDIC colspan=1Product/th
th class=cellTableHeader colspan=1Status/th
/tr
/thead
colgroup/colgroup
tbody style=
tr class=GA3XJ-DDEC onclick=
td class=cellTableCell cellTableEvenRowCell
cellTableFirstColumn
div tabindex=0 style=outline: medium none;car/div
/td
td class=cellTableCell cellTableEvenRowCell rowspan=2
div style=outline: medium none;
div class=greenCellOK/div
/div
/td
/tr
tr class=GA3XJ-DDEC onclick=
td class=cellTableCell cellTableEvenRowCell
cellTableFirstColumn
div tabindex=0 style=outline: medium none;car/div
/td
/tr
tr class=GA3XJ-DDEC onclick=
td class=cellTableCell cellTableEvenRowCell
cellTableFirstColumn
div tabindex=0 style=outline: medium none;car/div
/td
td class=cellTableCell cellTableEvenRowCell
div style=outline: medium none;
div class=redCellKO/div
/div
/td
/tr
/tbody
/table
But the point is that when the cell is rendered by the CellTable view, it
encapsulates it inside an other DIV and then put it in the TD. Then my Div
where I have applied a style will not have the max height of the TD so the
background color will not be fully applied to the TD. (The green of the OK
cell does not extend to the TD)
I got two ideas :
1/ Use css to extends the DIV to be the height of the TD. But setting
height: 100% did not work.
2/ Find a way to set manually a style to the TD. But there is nothing on
the CellTable api to access the TD after they have been rendered.
Is anybody have encountered this use case or have a solution please ?
Thanks in advance.

When is an object passed over RPC safe to modify?
We're experimenting with background saving in our GWT-app. IOW. we mark objects as 'modified', and then at regular intervals, find all modified objects and pass them to the database for storage. The question is when is it safe to mark the object as 'clean'. The on- success-handler of the save()-method is too late, obviously. That can happen any time later and the user might have modified the object(s) again. As the status also can be 'new' or 'deleted', I need to pass the status to the server so it knows what to do. IOW. I can't mark the object clean too early. What I'd like is to mark them 'clean' when they're safely serialized, and have the on-failure-handler set them back to 'modified' if the save() failed. So ... is there any point in the code where I can be certain that the objects are serialized and on their way to the server so I can start modifying them in the client without interfering? Figure 4 here: http://eclipse.dzone.com/news/making-gwt-remote-procedure-ca indicates that the objects are safe once the method in *Async returns. Is that safe?

Creating a reusable DialogBox with UiBinder?
Hi,
I'm trying to create a number of reusable dialog boxes using
UiBinder. Basically, I want to be able to call...
void someFn()
{
MyDialogBox box = new MyDialogBox(myConfigObj);
box.show();
}
... but I want to define the Dialog in its Own MyDialogBox.ui.xml
MyDialogBox.java files and the above code could be called in a number
of places.
So far I have:
!DOCTYPE ui:UiBinder SYSTEM http://dl.google.com/gwt/DTD/xhtml.ent;
ui:UiBinder xmlns:ui=urn:ui:com.google.gwt.uibinder
xmlns:g=urn:import:com.google.gwt.user.client.ui
ui:style
...
/ui:style
g:DialogBox autoHide=true modal=true glassEnabled=true
g:caption
btitle/b
/g:caption
g:DockLayoutPanel unit=PX width=700px height=450px
...
/g:DockLayoutPanel
/g:DialogBox
/ui:UiBinder
... and ...
public class MyDialogBox extends DialogBox
{
private static MyDialogBoxUiBinder uiBinder =
GWT.create(MyDialogBoxUiBinder.class);
interface MyDialogBoxUiBinder extends UiBinderWidget, MyDialogBox
{
}
public MyDialogBox()
{
uiBinder.createAndBindUi(this);
}
@UiFactory
DialogBox thatsJustMe()
{
return this;
}
}
This seems... wrong? Is there a better way?? I can't control the
dialog size with setWidth/Height.. it screws up royally.
Is there a tutorial?
And I DO NOT want to embed the dialog box in another UiBinder file as
I see all over the place.. its not reusable. (as in:

Re: Questions on image cell showing images, please help
Hi,
If you have ImageResource, you can use
com.google.gwt.cell.client.ImageResourceCell .
If you have only urls, you can create your own ImageCell like
com.google.gwt.cell.client.ImageCell and change html template used :
public class MyImageCell extends AbstractCellString {
interface Template extends SafeHtmlTemplates {
@Template(img src=\{0}\ style=\width:20px;height:20px;\/) //
20*20 size
SafeHtml img(String url);
}
private static Template template;
/**
* Construct a new MyImageCell.
*/
public MyImageCell() {
if (template == null) {
template = GWT.create(Template.class);
}
}
@Override
public void render(Context context, String value, SafeHtmlBuilder sb) {
if (value != null) {
// The template will sanitize the URI.
sb.append(template.img(value));
}
}
}

Hi, everyone
I tried to put some images in gwt cell table where I used image cells
to do this. But those images turned out pretty large in the webpage. I
tried to use aCellTable.setColumnWidth(column, width), but it didn't
help. I know if only to display a single image, I can say String url
= anImageResource.getUrl(); Image aImage = new Image(url);
aImage.setPixelSize(x,y); things like that. But how can I scale an
image in a image cell / cell table?
Some of my codes:
CellTableVehicleInfo vehicleCellTable = new
CellTableVehicleInfo(1);
.
ColumnVehicleInfo,String imageColumn = new
ColumnVehicleInfo,String(new ImageCell())
{
@Override
public String getValue(VehicleInfo object) {
return object.imageUrl;
}
};
vehicleCellTable.addColumn(imageColumn,Image);
vehicleCellTable.setColumnWidth(imageColumn, 3em); //doesn't help
.

General purpose RPC libraries
Hi, As I understand it, there's no way to compile a project without an entry point. I've been working on a project that defines 4 or 5 RPC interfaces (each defined as it's own GWT module) which subsequent projects will use, but which this project will not really use at all. Since I was working without an entry point, the deferred binding code and strong names required for serializing objects don't get generated until a project depending on the RPCs is compiled that has an entry point. The problem with this is that the original RPC, if ran, doesn't have any clue about the subsequent strongnames or serialization policies, so often fails for our result objects implementing Serializable. I suppose the way around this would be to create one generic/dummy module with an entry point in the RPC project, which inherits the others RPC modules/interfaces, but I was just curious if this would be the preferred solution or if there was some other way around this that I'm not aware of. Also, will a project that inherits the dummy module receive all the strongnames and serialization policies (I haven't tried this yet) -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

printImageWidth(testImg); // will print 0
testImg.addLoadHandler(new LoadHandler() {
public void onLoad(LoadEvent event) {
printImageWidth(testImg); // will print a number

Re: GWT 2.2 Celltable Paging
Hi,
I think you should use :
cellTable.setRowCount(result.size());
cellTable.setRowData(0, result);
instead of :
cellTable.setRowData(result);
Javadoc of

Hi,
I have the following problem. I have a celltable with 2 columns. These
columns contain Filenames and their size.
Due to the fact that i have many files that i want to display I want
to use Paging. In my last project i used gwt 2.1 and the paging worked
there. The simplePager in GWT 2.2 does not work in my new project but
its still the same code that should work.
Can anyone show me where it goes wrong? Thanks.
Here´s my code reduced to the SimplePager things:
public class CellTableTestClass {
private VerticalPanel applicationPanel = new VerticalPanel();
private CellTableLogData cellTable = new CellTableLogData();
private SingleSelectionModelLogData selectionModel = new
SingleSelectionModelLogData();
public VerticalPanel createContent() {
LogFileServiceAsync initData = (LogFileServiceAsync)
GWT.create(LogFileService.class);
initData.getLogs(new AsyncCallbackList LogData() {
public void onFailure(Throwable caught) {
Window.alert(caught.getLocalizedMessage());
}
public void onSuccess(ListLogData result) {
cellTable.setRowData(result);
}
});
cellTable.setSelectionModel(selectionModel);
{
cellTable.addColumn(new TextColumnLogData() {
@Override
public String getValue(LogData object) {
return object.getLogName();
}
}, Log Name);
cellTable.addColumn(new TextColumnLogData() {
@Override
public String getValue(LogData object) {
return object.getSize();
}
}, Size);
}
// create a pager, giving it a handle to the CellTable

GWT.create(SimplePager.Resources.class);
SimplePager pager = new SimplePager(TextLocation.CENTER,
pagerResources, false, 0, true);
pager.setDisplay(cellTable);

Re: expand ListBox as droplist using keyboard

Re: [gwt-contrib] Re: [RFC] GWT Widgets that ROCK!
Hi,
I'm fairly new in the GWT development but I'm not sure that the selected
development answers the initial need. Let me explain you why (sorry it is
rather long). It is also very possible that I'm completely wrong.
The main goal is allowing the developers to easily theme their application.
As a developer I know I'm not good at designing a theme, in the end it
always looks ugly. What I want is to be able to browse the themes and say
Oh this one looks nice, I'll pick that one!. And then, I just want to
download it, add it to my project, add one configuration line that says now
on, use this theme.
A developer might also have a button in his application that is pretty
special: clicking it will erase everything in the database. He wants to have
a button that doesn't look like the other ones. He wants to be able to
define somewhere a new style for a button with a 10px red border (it's
probably good to ask for the help of a designer at this point...).
Now, lets turn around and have a look at the designer perspective. He wants
to create a theme, he had the nicest ideas. He doesn't really know how to
develop simply because it's not his job, but he is really good at creating
the CSS and HTML that match his Photoshop mockups. If the pre-existing DOM
structure of the widget doesn't match his needs he should be able to simply
redefine it.
A designer might also wants to tweak a little bit an existing theme (the
default one for instance). Imagine that he wants to update how Tabs are
rendered and just that. He should be able to do so.
Therefore I think that:
- Creating a theme should only require to create:
- a package that contains it
- a simple class that inherits the base theme (the default one or another
one).
- a .css file with the name of widget to redefine its style
- a .ui.xml file with the name of the widget in order to change its DOM
structure
- Using a theme should only require to point to the right theme class
The advantages are:
- The rendering of a widget and its style are defined in HTML-like and CSS
files.
- The themes are simple to create/update/use
- If the default theme changes or new widgets are added then there are no
impact on pre-existing themes.
Now pseudo code samples, it doesn't compile, it just illustrates.
First the base Theme class and the Button widget class.
// This is the base theme the class that all theme should extends.
// This annotation indicates that GWT.create should always return the same
instance.
@Singleton
public class Theme {
protected interface UI {
// The creation is performed based on the @UiTemplate annotation
public Element render();
// Inject the CSS based on the @CssSource annotation
injectCss();
}
@UiTemplate(button.ui.xml);
@CssSource(button.css)
public interface ButtonUI extends UI {
// Automatic wiring due to the @UiField annotation
public void setLabel(Element element, @UiField(label) SafeHtml label);
}
private ButtonUI buttonUI = null;
public final ButtonUI getButtonUI() {
// Lazy loading
if (buttonUI == null) {
buttonUI = GWT.create(ButtonUI.class);
buttonUI.injectCss();
}
return buttonUI;
}
// This defines the base style such as the font name and size.
// It isn't linked to any widget but rather to the body element
@CssSource(style.css)
public interface PageStyle extends CssResource {}
}
public class Button extends NewWidget {
private final Theme theme;
private SafeHtml label;
public Button() {
// This should always returns the same instance
this.theme = GWT.create(Theme.class)
// Render the button, it creates a new DOM structure
// The CSS should already be injected
setElement(this.theme.getButtonUI().render());
}
public Button(SafeHtml label) {
this();
setLabel(label);
}
public void setLabel(SafeHtml label) {
// We save it because we cannot retrieve it from the UI
this.label = label;
// Update the DOM with the new label
this.theme.getButtonUI().setLabel(getElement(), label);
}
}
The default button.ui.xml looks like that:
ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'
button class='gwt-button'
span class='icon' ui:field='icon'/
span class='label' ui:field='label'/
/button
/ui:UiBinder
The related button.css looks like that:
.gwt-button { /* Style in here */ }
.gwt-button icon { /* Style in here */ }
.gwt-button label { /* Style in here */ }
Now the new theme class:
public UglyTheme extends Theme {
// Nothing in here
}
...with its really ugly button.ui.xml:
ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'
table class='gwt-button'
tr
td class='topleft' /
td colspan='2' class='top' /
td class='topright' /
/tr
tr
td class='left' /
td class='icon' ui:field='icon' /
td class='label' ui:field='label' /
td class='right' /
/tr
tr
td class='bottomleft' /
td colspan='2' class='bottom' /
td
Re: [gwt-contrib] Re: [RFC] GWT Widgets that ROCK!
With the appearance pattern your proposed Theme class would be the same as a GWT module containing all the deferred bindings for changing all the appearance classes of all widgets. So you would inherit this theme module and you are done. I think you could also overwrite a specific deferred binding in your app module if the compiler always picks the last matching rule. Or am I missing something? But indeed it would be nice to have a UiBinder template (or a general xml template) which defines the DOM structure of a widget instead of a render method. That way we could pass the widget.ui.xml and its widget.css file to a designer and the developer only has to deal with the appearance class and event handling. But with a separate xml template I guess it may be difficult for a developer to implement the onBrowserEvent method because he can not assume any given DOM structure for a widget (each theme may have changed it drastically). So as you pointed out, event handling will be the major issue. But maybe there is a solution for it? I really like the idea of decoupling the DOM structure and having a separate xml file for it. -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
[gwt-contrib] Re: [RFC] GWT Widgets that ROCK!
I am wondering if you are considering to use html5 widgets if available and provide a fallback gwt implementation for browsers that do not (yet) support widgets like http://slides.html5rocks.com/#semantic-tags-2 I think in general GWT has the right tools for using native browser stuff whenever available and providing some js-pendants if they are not supported. -- http://groups.google.com/group/Google-Web-Toolkit-Contributors

I brought this up on the public thread, and most people who commented on
this issue said that they are used to duplicate names in Eclipse and
would rather we just choose the best name than try to make them unique.
Also, only people who extend button will see ButtonBase. Most people
will use TextButton.
