 Hello,
 
I actually need a composite panel TournamentField that consists of two 
widgets, a label and a button at the right of the label. I want that the 
label always consumes most available horizontal space, while the button has 
a fixed size.
 
[ label with variable width][button]
 
Below is the code.
(The HorizontalLayoutPanel is just a FlowPanel which sets float:left; on 
its children, as supposed by the article Moving to standards mode in the 
GWT docs.
 
As you can see, I even needed to use a hard coded size for the height of 
the label, because I do not know the default height...
 
This TournamentField is added to a LayoutPanel.

Re: fundamental problems with predictive layout

2012-09-03 Thread Ümit Seren

Are you changing the sizes of the layoutPanels dynamically? Because if
you don't it should work out of the box.
If you are changing it dynamically then you might run into this bug
(http://code.google.com/p/google-web-toolkit/issues/detail?id=7188). I
found following code snippet in one of my projects:

layoutPanel.setWidgetSize(this.asWidget(), size);
/*workaround for bug
http://code.google.com/p/google-web-toolkit/issues/detail?id=7188*/
layoutPanel.animate(0,new AnimationCallback() {

@Override
public void onLayout(Layer layer, double progress) {
}

@Override
public void onAnimationComplete() {
layoutPanel.forceLayout();
}
});;


On the other hand if you have simple elements (like in your use case)
you could just rely on CSS settings (float, etc) as Andrei pointed
out, although depending on your actual use case you might have to
calculate the sizes and set them explicitly.

Re: fundamental problems with predictive layout

2012-09-03 Thread Jens

In pure HTML I would do it like:

http://jsfiddle.net/EHCGu/

you can drag the vertical splitter to change the size of the result and the 
label div fills all the space while the button is float:right. No need to 
use any onResize() JavaScript as the browser takes care of the size. Maybe 
you can omit the  div that clears the float:right.

You should use as much CSS as you can, so you don't have to worry about 
resizing your widgets. Let the browser do it.

In

you call

getStyle().setProperty(wordWrap, breakWord);

but I think it should be

getStyle().setProperty(wordWrap, break-word);

Re: How do you get uiBinder to inject its style code immediately?

2012-09-03 Thread Artem Artemyev

Hello!
Im trying to find a solution too and I stop on your resolving way: static 
boolean in the widget and injection by StyleInjector. But invoking 
StyleInjector.inject( style.getText(), true ); force inject styles and after 
few moments styles injected again! It happens because 
uiBinder.createAndBindUi(this) invoke style.ensureInjected(), that invoke 
StyleInjector.inject( style.getText(), FALSE ); that add style injection to 
the queue in the StyleInjector. Fortunately StyleInjector provide flush() 
method... 
And final solution is:

@UiField
Style style;

private static boolean styleInjected = false;

public SomeWidget() {
widget = uiBinder.createAndBindUi(this);

if (!styleInjected) {
styleInjected = true;
StyleInjector.flush();
}
}

Very weird behavior of OptionalFieldEditor

2012-09-03 Thread Jeff

 Hi, 

I am using the following editor to support a nullable list: 

public class NullableListEditorT, E extends EditorT extends Composite 
implements IsEditorOptionalFieldEditor ListT, ListEditorT,E  { 
private ListEditorT, E list = ListEditor.of(new ListEditorSource()); 
private final OptionalFieldEditorListT, ListEditorT, E  editor = 
OptionalFieldEditor.of(list); 
… } 

NullableListEditor for type A and B:
public class NullableAListEditor extends NullableListEditorA, AEditor 
{..} 
public class NullableBListEditor extends NullableListEditorB, BEditor 
{..} 

If I use both editors in my application, say first create 
NullableAListEditor and then NullableBListEditor, NullableAListEditor will 
work fine but NullableBListEditor will fail with Error:

in line 75, for NullableBListEditor , the type returned by 
createComposedDelegate()is the same as that of 
NullableAListEditor(editor_A_AEditor_SimpleBeanEditorDelegate). As a 
result, the 
subDelegate type is not correct for B and caused the above errors during 
attaching. (If I create B then A, B will work but A will fail for similar 
errors)

I couldn’t figure out why. Anyone knows how to fix it?

Thanks a lot,

GWT Script running too long error - and solution?

2012-09-03 Thread zsomi83


Hi All,

I have the following problem:
A piece of code running too long for the Browsers (both for IE and Mozilla).

This is a while cycle searching for RootPanel of a widget.

While I was debugging I found that if I put Window.alert it operates correctly, 
no pop-up from browser.
Finally the following solution solved the problem:

while (null != w) {
//check if w is a composite
try {
Composite tmp = (Composite) w;
tmp.isAttached();

wLastComposite = w;
wLastCompositeChild = wChild;

wChild = w;
w = w.getParent();

continue;
} catch (Exception ex) {
//not Composite, do nothing
}

!START solution: Added only this line
long end = System.currentTimeMillis();
!END of solution
//check if w is a RootPanel
try {
RootPanel rpTest = (RootPanel) w;
rpTest.isAttached();
w = null;
foundRootPanel = true;

break;
} catch (Exception ex) {
//not RootPanel, nothing to do
}

//continue with its parent
wChild = w;
w = w.getParent();
}

Now, its running fast. Like 1 ms. 

Can you please tell me WHY???

Approximately 6 iteration needed, this is what I found during debug. I do not 
think, this shall last more than 10 sec (Browsers limits) by default.
And the issue occurred after we upgraded to 2.1.
I understand, that GWT is single threaded, and the only think I can think of 
that system call somehow make an interrupt.

So two questions: 
- why does not it work??
- why this system call solves the issue??

Thanks in advance for your answers/explanation!!

BR,
Zsomi

How long is the reviewing process?

Hi,

Friday noon, I posted a question about weird behavior of 
OptionalFieldEditor. But I haven't seen it online yet. Is it expected?

thanks,

It would be great if it worked. I installed it with the older Eclipse version

The GWT dev plugin does not work!

abstract base classes, error

2012-09-03 Thread timp

Ok my question hasn't been posted, but I've found, what I think is the
solution. I'm not exactly certain if I'm doing things correctly yet, but,
to save some other poor soul 8 hours of their life.

If you are having problems with OutputStream or any other part of the
standard JRE.
let's say you are getting: write(int) is undefined for class OutputStream

take a look at:
https://groups.google.com/forum/?fromgroups=#!topic/Google-Web-Toolkit/kz1RH1JMw1U

specifically this:
https://developers.google.com/web-toolkit/doc/1.6/DevGuideOrganizingProjects
and
http://code.google.com/p/gwt-in-the-air/source/browse/trunk/super/net/ltgt/gwt/air/emul/Emulation.gwt.xml

basically what you want to do is:
in source trunk, assuming you made a java and javax tree with custom java
files, cause you thought you will fill in places in GWT

mkdir jre
mv java jre
mv javax jre

cd jre
cat JRE.gwt.xml

?xml version=1.0 encoding=UTF-8?

!DOCTYPE module PUBLIC -//Google Inc.//DTD Google Web Toolkit 2.4.0//EN
http://google-web-toolkit.googlecode.com/svn/tags/2.4.0/distro-source/core/src/gwt-module.dtd;

module

super-source/

/module

cd ..
go into whatever your main project is and do your usual inherit:

?xml version=1.0 encoding=UTF-8?

module rename-to='mailiverse'

!-- Inherit the core Web Toolkit stuff.--

inherits name='com.google.gwt.user.User'/

inherits name='jre.JRE'/

Seems to work.

-tim

p.s. google, your new newsgroups have lots of errors. why not fix this.
it's 2012 and we have errors reading newsgroups?
what is the cut off date when things actually work? 2050? Why is the bar
just so low for all of these technologies?

oh well.
take for instance this google groups window I am writing in 20% of the
screen space write now. I can't even see my whole post.

80% of the screen is the stupid google bar + google search + google welcome
to google+ google post + my groups + google web tookit title in a
mysteriously huge font + by me (I know who I am) + subject, ok fine +
blahblahblah

I can't even see my own post, who is this stuff designed by? no one?
god I am a troll, but jeeze this stuff is so poorly done. It's like no one
cares.

Re: CellTable - style specific columns

use css selectors to id your datagrid or cell table container. and by use child 
and exclusion selectors u should be able to spefic the style on the td. u can 
also use css expressions or some jsni for quick and dirty impl. however i woukd 
implement it using my own custom cells to render via safe html templates. this 
would allow u to not only wrap the inner content with a div for overflow 
handling and or tooltips. iylt would also be the easiest way to specify a class 
and or id name or other atreibutes. u could crawl it with the dom and element

Re: Spring Roo, relationship status with GWT? recommended for more apps more complex than basic CRUD?

2012-09-03 Thread RomanK

Hi,

I might have the answer to question 2:
With the latest version of Roo (1.2.2) you can tell Roo to create only the 
Proxy and Request layer. Here are two command samples from the 
documentation:
A.13.5. web gwt proxy request all

Locates all entities in the project and creates GWT requests and proxies

web gwt proxy request all --package

--package

The package in which created proxies and requests will be placed; no 
default value (mandatory)


A.13.8. web gwt request all

Locates all entities in the project and creates GWT requests

web gwt request all --package

--package

The package in which created requests will be placed; no default value 
(mandatory)


All GWT related roo commands can be found in chapter 13 under the following 
link:

http://static.springsource.org/spring-roo/reference/html/command-index.html 

 Hope that helps.

 Hi all,

 I came across Spring Roo recently and have put in a considerable amount

 1) GWT support:
   Spring Roo integration with GWT (more specifically the gwt addon for 
 Roo to make MVP life easier) was presented back in 2010 in the IO keynote (
 http://www.youtube.com/watch?v=GQHlhIIxCIc) and in a talk by Ray Ryan (
 http://www.youtube.com/watch?v=M5x6E6ze1x8) and it seemed promising. 
 However, in all my googling it seems like the gwt-roo presence/community 
 has been sorely lacking, is it just me? Is GWT still on the Roo bandwagon?


 AFAICT the GWT add-on for Roo was a joint effort, but Google has not been 
 involved after the first release (milestone?).

 For all your other questions, you'd rather ask the Spring Roo community 
 then.

gwt abstract classes, error

2012-09-03 Thread timp

So.  from the gwtquake, I ripped your:

package java.io;

public abstract class OutputStream {

// not abstact because of some gwt strangeness
public abstract void write(int b) throws IOException;

public void write(byte[] ba) throws IOException {
write(ba, 0, ba.length);
}

...

and I ripped the:

package java.io;

public class ByteArrayOutputStream extends OutputStream {

  protected int count;
  protected byte[] buf;
 
  public ByteArrayOutputStream() {
this(16);
  }
  
...


-


I have the code:
ByteArrayOutputStream bos = new ByteArrayOutputStream ();
bos.write(1);

And that works fine.

But then I have the code:
OutputStream bos = new ByteArrayOutputStream ();
bos.write(1);

And it fails with:

[ERROR] [] - Line 139: The method write(int) is undefined for the type 
OutputStream



But it is defined.  I have tried putting in dummy bodies, declaring things 
abstract, non-abstract, changing the throws declaration, changing the class 
declaration, removing those @override from the child classes.  to no avail. 
 I have tried changing the inherits of the various components, changing the 
names of the inherit files, changing blahblahblah.  ridiculous number of 
things.



My question is two fold:

1.  How should I go about debugging this?  Trying random things is not 
wonderful.
2.  Is there a list of gotchas for GWT?  (Things that should work but 
fail)


Thanks,

bouncy castle, jordan zimmerman, biginteger, binary resources

2012-09-03 Thread timp

I thought you guys would like to know that it appears the Apache Harmony's 
BigInteger is exactly compatible with Sun's.

I have bouncy castle's rsa,aes as well as jz's srp working with no problems.
Although, when I debug GWT from eclipse+chrome is it running within a 
javascript vm, or am I still in java land? 


I was wondering whether anyone has any comments about this code:

native String getBinaryResource(String url) /*-{
// ...implemented with JavaScript 
var req = new XMLHttpRequest();
req.open(GET, url, false);  // The last parameter determines whether 
the request is asynchronous - this case is sync.
req.overrideMimeType('text/plain; charset=x-user-defined');
req.send(null);
if (req.status == 200) {
return req.responseText;
} else return null
}-*/;

Is this going to cause problems later on?  Is there a more proper way I 
can do this with GWT?

Thanks,

-tim

 I am brand new to GWT and just trying to get the hang of things.  I
 
 followed all the steps in the StockWatcher tutorial, and it worked

 When I opened it in Chrome, all I could see were the GoogleCode image
 
 and the Stock Watcher title; anything generated by javascript was just
 
 missing.
 
 
 
 I really don't know how to debug this since I have limited experience
 
 with any web development.  My only theory is that the compiler output
 
 might suggest that there is a path problem.  My compile output says:
 
 Linking into /Users/bcutler/Documents/workspace/StockWatcher/war/
 
 stockwatcher
 
 
 
 ... but in the tutorial the same line says:
 
 Linking into war/stockwatcher.
 
 
 
 Could this be the problem?  If so, how do I fix it?
 
 
 
 For what it's worth, I tried opening the file in Firefox as well.  The
 
 page loaded just fine in Firefox and the javascript seemed to work
 
 perfectly, except that pressent Enter on the text box doesn't do
 
 anything.  Isn't GWT supposed to fix the cross-browser problem?
 
 
 
 I am using Eclipse 3.7 (Indigo) with the GWT plugin and version 2.4.0
 
 of the SDK.

Re: GWT 2.5 RC1 Is Here!

2012-09-03 Thread gilpgnet

I think all depends on the kind of applications you are writing. I've 
successfully tried with JSF and Java Script frameworks for simpler things, 
but for the most elaborated designs I allways get back to GWT after a lot 
of rearch on other alternatives.

HTML 5 has has many of the GWT features in a simpler way, but GWT gives you 
the integration and support for bigger projects. A disadvantage of GWT may 
be that it needs all of the code before compiling, but there are 
also design patterns that allow to implement dynamic stuff.

 If you don't like the Google way you can count on 

* Scala+GWT ( http://scalagwt.github.com/ ) if you want another language
* Tessell (http://www.tessell.org/) for MVP and other
* Errai ( https://www.jboss.org/errai ), if you like a very easy, poweful 
and JEE integrated enviroment

and on code.google.com you can find

* GIN and GUICE for the same above but tho Google way
* m-gwt, excellent tool for mobile
* gwt-platform (MVP, Support for search crawling)
* guit (MVP and a lot of stuff yo simplfy your work)
and a lot more.

These are my tips, but as always, it's all up to you.

 OptionalFieldEditorAddressProxy, AddressEditor
 implements HasRequestContextAddressProxy, IsWidget {
 ...
 @Override
 public Widget asWidget() {
 return this.addressEditor;
 }
 }
 To be able to use this field as part of your view /uiBinder you have to 
 extend isWidget and return the actual addressEditor (passed in as part of 
 the constructor) via asWidget(). 
 There are three possible scenarios here: New Person/New Address, Edit 
 Person/New Address, Edit Person/Edit Address.
 To be able to grab the address editor changes via the context, it seems 
 trivial to create the AddressProxy (if non existent) prior to editing. The 
 problem with this approach is that if you create a Person from scratch or 
 if personProxy has no addressProxy already attached to it, and user don't 
 fill out the address at all, you have already created an addressProxy which 
 haunts you in validation (I don't know how to get around this one). Even 
 returning null after flushing and before firing the context has no affect. 

 To get around the validation issue, fake addressProxy seems to be the 
 solution but If your validation resides on the server (like my scenario), 
 there is no way to avoid actually saving the fake proxy. Your fake proxy 
 needs to go all the way to the db since your sql carries the constraint as 
 well and that means you have to interpret the fake values. 
 In the client, upon rendering the fake address proxy recognize the fake 
 value and empty out the fields. (setValue of the optionalFieldValue).

 Thank you Thomas again, it has been a good learning process but with the 
 limitations we have, I resort to removing all the constraint on the Address 
 domain, at this point it seems to be the lesser of the evils.

Re: Best serverside architecture(framework/stack) to use with GWT for large application...please show me the light

hibernate with jpa beans. run onto of a restful java servlet to serve up your
DAL. if your not good with dep inj design use GIN and Guice for instantiating
your widgets and composites. also if your new to gwt use the ui binder.
advanced create a viewport and screen manager to inject your classes. and
oracle for db since it works nicely with run native behind the scenes of your
plsql views that u create in your db. also for quick and dirty apps use
springroo to architect and develop your back end.

Re: What is the proper way of implementing page-level select-all through a Checkbox Header in a CellTable

this works with true and true set on the CTOR of the checkbox header cell, 
however this does not persist though multiple pages becuase you are only 
referencing the visible items. working on implementing a post processor to 
the updaterowcount and updaterowdata method calls. if we use a flag to 
determine when select all was toggled, then we can execute the post process 
to update new pages of visible records as the user toggles though them. 
Also during user interaction such as batch editing on all selected items, 
we can check to see if the flag is up, and apply this to all records 
regardless if the user has paginated to them yet. fun fun. Im still a bit 
curious to as of why google has not included this functionality into there 
datagrid release. Is it just that new??? Neways thanx for the pointers it 
saved me a bunch of time today.

 However, I still haven't found I clean answer to what seems to me a
 very common feature requested in data presentation (and editing)
 grids.

 In summary we want to be able to add a checkbox header to a selection
 column of checkboxes that:

 * Checking it will select all visible items in the grid.
 * Unchecking it will deselect all visible items in the grid.
 * Any change in the visible data, caused for example by paging or
 sorting, will result in the checkbox header value to be updated
 according to the rules above: if all visible items are selected then
 check it, otherwise uncheck it.

 The straightforward logic would suggest that the following
 implementation should work:

   CheckboxCell headerCheckbox = new CheckboxCell();
   HeaderBoolean selectPageHeader = new
 HeaderBoolean(headerCheckbox) {
 @Override
 public Boolean getValue() {
   for (T item : grid.getVisibleItems()) {
 if (!getSelectionModel().isSelected(item)) {
   return false;
 }
   }
   return grid.getVisibleItems().size()  0;
 }
   };
   selectPageHeader.setUpdater(new ValueUpdaterBoolean() {
 @Override
 public void update(Boolean value) {
   for (T item : grid.getVisibleItems()) {
 getSelectionModel().setSelected(item, value);
   }
 }
   });
   grid.insertColumn(0, checkColumn, selectPageHeader);

 However, the result is not the expected:

 * When updating the visible data, lets say by moving to the next page,
 the getValue() method gets called. The first couple of calls,
 getVisibleItems() returns empty, and then it returns the new not-yet-
 selected data. In each case, getValue() returns false. However, this
 produces no change in the checked state of the header. This in itself
 seems like a bug to me.

 * When just toggling the checkbox header, this ends up in the opposite
 state than desired. Even though update() gets called with the proper
 value that reflects the checkbox header state, and the last calls made
 to getValue() result in the proper value being returned. The only
 irregular logic I see that could cause this, is that when clicking
 on the header, the getValue() method gets called before the update() -
 to obtain the key and create a cell context. That results in
 getValue() returning the wrong value (i.e. the opposite). However,
 after update() gets called and it sets the selection state of the
 visible items, getValue() gets called again, thus returning the proper
 value this time.

 I guess there are ways where the header can be created in a way where
 we can control better how its value is set and retrieved. However,
 this being such a common use case, and whose logical implementation
 shown above produces inconsistent results, tells me that either I'm
 completely missing something, or that this is a flaw in the celltable
 widgets.

 I would appreciate any input on this regard,

 Thanks

 Hi,

 Thanks for your well written post. It appears that your solution works 
 well if you construct the CheckboxCell with the right flags:

 new CheckboxCell(true, true)

 the two booleans are handlesSelection and dependsOnSelection, and they 
 cure the weird event ordering issues you were seeing.

Re: [gwt-visualization-api] Export chart to image

 Hi guys,
 
 My team is working on an application that uses Google Image Chart api to 
 generate a few charts. We are finishing a new analysis component and the 
 number of generated charts will increase a lot. So, we'd like to use a more 
 sofisticated solution. The new google visualization api appeared to be 
 perfect for us. But we noticed there is not a feature to export the SVG chart 
 as an image which is necessary for us. 
 
 
 We could continue to use the Image Chart Api to provide the export feature, 
 but the problem is that it seems to be deprecated. If we make the same call 
 to a ImageLineChart and to a LineChart, for example, we see that the labels 
 of the Image Chart are overlapped. Therefore, it doesn't seem smart to use 
 both apis.
 
 
 So, I would like to know if there is a workaround for this problem.
 
 I would also be thankful for suggestions of other non-flash solutions for 
 charts, that can be easily exported.
 
 Thanks in advance.

Hi Renato,

i've been using the aka visualization API form displaying interactive charts in 
my GWT applications. Now i have the need to include these charts in a PDF 
report. I am planning to use the deprecated Image Charts API to create image 
files which can be included in my PDF file, but i don't think using different 
APIS for different purposes is a good option either.

Some alternatives i've found on the web are the following:

a) saving google interactive SVG charts as images using JavaScript code:
http://www.battlehorse.net/page/topics/charts/save_google_charts_as_image.html

b) making a screen-shot of the browser by means of a tool like this one:
http://code.google.com/p/speak-lib/source/browse/#svn/trunk/WebShot%3Fstate%3Dclosed

I've seen you had the same doubts some mounths ago, but i don't see any 
responses...did you finally come up with a finer solution for converting 
interactive charts to images?

Thank you in advance

Victor

Re: Clear Cell table data

try updating your row count and row data.

getDataGrid().setRowCount(getDataCount(), true);
getAsyncDataProvider().updateRowCount(getDataCount(),
getAsyncDataProvider().updateRowData(getOffset(), getDataList());

rather then using my async provider you would get your list provider or
whatever else. This provider is bound to the cell table (datagrid and cell

Re: DART vs. GWT

umm no.

On Tue, Aug 28, 2012 at 11:02 AM, Chris Lercher cl_for_mail...@gmx.netwrote:

 About Dart:

 - I really (!) hope that Dart will succeed.
 - Ideally, Dart would even become the new JavaScript alternative in all
 browsers (however, AFAIK a few browser vendors have signaled, that this
 ain't gonna happen). If not, then it could maybe still be successful with
 dart2js.

 About GWT:

 - GWT allows to code in *Java* for the client side, which is perfect, if
 you already use *Java* on the server side.
 - There is no significant amount of existing Dart code for the server
 side, so Dart does not have that advantage.

 Conclusion:

 GWT + Dart would be such an awesome combination: GWT compiling Java to
 Dart. And then Dart to JS only if necessary.

 - This would require changing GWT internals,

 - but it wouldn't require changing the GWT API and programming techniques
 much (except for low level JSNI and JSO) - remember, that a lot of the GWT
 API is about manipulating the DOM (which stays the same no matter if the
 underlying language is JS or Dart), handling browser events, ...

 - As long as you want to work with Java on the server side, it's a good
 idea to use GWT - otherwise you'd have to duplicate common parts of your
 code for the server (Java) and client side (Dart) - like in the medieval
 days before GWT. (I hope we'll never have to fall back to that situation.)

 Alternative:

 The alternative would be that Dart also succeeds on the server side,
 completely replacing Java. This is rather unlikely, but if things like O/R
 mapping, fully-fledged IDEs, and anything of value that Java provides is
 available in Dart someday, plus if it provides any real advantage over
 Java, then I'm the first one to switch completely to Dart. Then we wouldn't
 need GWT anymore, and Dart would probably adopt all useful GWT features.
 (And it should be straightforward to port existing GWT code to Dart.)

Re: how to write a 2D game by using GWT and html5.

its as simple as creating a while statement or a timer that fires a method 
called update every frame. in that method you would update all of the 
objects in your level. By using some simple physics equations you can apply 
acceleration and gravity.

definately check out playn though.

 Based on my experience in GWT so far, I know I can just use plain GWT and 
 GWT-animation to achieve what I want. This is the easiest way for me to 
 achieve. However, I hope I can make the game look and feel a bit more 
 professional and attractive. So GWT-Canvas may be the good option for me to 
 write the animation. Physical reactions and Audio are also the important 
 concern. 
 Please give me some advices about the following questions.

 1. To write the animations, which technique should I use, plain 
 GWT-animation or GWT-Canvas+HTML5. Which one has better performance? (the 
 game will be running on the webpage, so the level of performance is the 
 most important for me)
 2. Is there any good libs I should definitely use for writing 2d games? I 
 do not prefer the complicated lib because my game is pretty simple.
 3. I am considering using some game engine. My game is easy and simple, I 
 could make a fake physical reactions by just using some math functions to 
 run the animations. but if the game engine is easy and handy to use, then I 
 would prefer using game engine. So is there any good one out there for 
 beginners?
 4. Please give me some advices about making the game audio. are there any 
 good audio libraries for GWT projects?

 Thanks.

GWT Window.localtion.assign redirect is not working in tomcat/jetty server

2012-09-03 Thread ranjan

 ** 

i am using gwt to create a web application.

when a user presses the logout button, i want to be able to refresh the 
page(or basically redirect to the homepage)as my GWT application runs only 
on one html page.

what is the programmatic code to do this?

I am doing Async calls to to the server side on button click  and able to 
clear the cookies and refresh as well , but redirect is not happening .

i am using Window.localtion.assign (GWT.getHomePageURL+index.html)   on 
the client side code , but it's not  redirecting to index.html .

one more observation is it is working in DEV environment but once deployed 
on external servers like Tomcat/Jetty , redirect is hot happening , all the 
time  its going to some other page.

Any suggestions will be highly appreciated ... 

 

Thanks,

Ranjan

Unable to create GWT Library using 3.7 and Eclipse Indigo.

Trying to create a new GWT Library project for UI components that are to be

said I am on 3.7.  But in the link below it shows a screenshot of Eclipse 
Wizards that looks nothing like what I am looking at.  I am surprised there 
isn't more info about this out there.

GWT Mobile App in Same WAR File

2012-09-03 Thread jduffy


Hi All,

We are developing a GWT application for desktop browsers that is deployed 
to a Tomcat 7 container as a WAR file.
We are also developing a companion mobile application that is written in 
JavaScript and JQuery.

We would now like to embed both applications into the same WAR file so that 
the appropriate version is served based on the user-agent property of the 
browser.

For example, if a user hits 'ourapp.com' from a desktop browser, they 
should be served the GWT application and if they hit it from mobile Safari 
on an iPhone, they should get the JavaScript/JQuery application.

Can anyone shed some light on how we might be able to accomplish this?

We're fairly new to GWT and web programming so I apologize if the question 
is a bit vague or non GWT specific.

Jim

RequestFactory collects request calls after onConstraintViolation response

2012-09-03 Thread Manuel Schrag

Hello,

We're having a problem using the request factory in GWT 2.5 RC1. When 
calling *rejectBankCheck() *on the activity, it happens that there are bean 
validation errors. The service method corresponding to this request call is 
not invoked. By correcting the errors on the UI and clicking on a button, *
rejectBankCheck()* is called again. This time, the receiver gets *onSuccess(). 
*Everything looks fine, but I can see that both,* onSuccess()* and the 
service method corresponding to *rejectBankCheck()*, are invoked twice!

public void rejectBankCheck(String remarks) {
   request.rejectBankCheck(entity, remarks)
  .fire(new ReceiverProtocolProxy() {

  @Override
  public void onSuccess(ProtocolProxy response) {
display.onRejectSuccess();
  }
  @Override
  public void onConstraintViolation(SetConstraintViolation? 
violations) {
display.setConstraintViolations(violations);
  }
   });
}

My first intention was to split this in two steps:

   1. initialize the receiver when the activity starts
   2. when the user clicks on the button, just call *fire()* on the request 
   context

This isn't possible, because the parameter *remarks *of the method is a 
user input and can change between the two invocations. So I have to call 
*request.rejectBankCheck(entity, 
remarks)* every time the user clicks.

Here are my questions:

   1. Is this a bug or a feature of the request factory? At the moment, I

Re: Spring and gwt (request factory)

2012-09-03 Thread Miłosz Pacholczyk

Hello, 

have you found a way to configure it properly? 

If so, would you mind posting samples for web.xml and 
applicationContext.xml?
I have a very similiar code, but I got stuck at wiring it all.

Re: fundamental problems with predictive layout

 Hi,
 
 since I use GWT I have a fundamental problem with implementing a predictive 
 layout. I did many resize operations using the onResize method. This method 
 is called whenever a widget is resized. This is fine.
 However, it is only possible to react on a resize event if one knows the new 
 sizes!!
 
 Consider a composed widget, with an outer panel and some child widgets. In 
 order to resize the child widgets, I need to know the actual size of the 
 outer panel. But this size is not known in most cases.
 In almost every onResize method I was not able to detect the *new* size of 
 the object being resized. Calling getOffset[Width|Height] nearly always 
 results in wrong sizes, old sizes.
 
 One method to deal with this is to schedule the onResize code after the 
 current events are processed. But these retarded resizing codes cascade, when 
 there are composite widgets that must delegate the resize event to their 
 children. And cascading this stuff makes it slow.
 
 So given a composite widget, with a horizontal fixed (left) component, and a 
 variable (right) component: How can you make this resizable?
 
 Thanks
 Magnus

GWT Library feature missing in GWT 3.7 plugin for Indigo?

2012-09-03 Thread B-RI

Hi -

I am trying to create a GWT Library (that I will be using for a UI widget 
library) - that will be shared with many other web projects.  I found 
information on creating a GWT Library, but my Eclipse (Indigo) is missing 
the GWT Library Wizard, and I cannot find any additional information on 
that.  What is the best way to create a separate widget library in Eclipse; 
is it best to link to a JAR, or to set the project references in Eclipse (I 
lean toward the later if possible).

I have only one option in Eclipse New Web Application Project - and don't 
see any of the options shown in this link.

RequestFactory collects request calls after onConstraintViolation

2012-09-03 Thread Manuel Schrag

Hi,

I have the following method in my activity:

public void rejectBankCheck(String remarks) {
request.rejectBankCheck(entity, remarks)
.fire(new ReceiverProtocolProxy() {

@Override
public void onSuccess(ProtocolProxy response) {
display.onRejectSuccess();
}
 @Override
public void onConstraintViolation(SetConstraintViolation? violations) {
display.setConstraintViolations(violations);
}
});
}

On the UI, the user enters remarks and clicks on a button. This invokes *
rejectBankCheck()* on the activity. The current request is now fired with 
the associated receiver. It happens that there are constraint violations 
which the user then corrects and reclicks on the button. This time, the 
receiver gets onSuccess(), so everything seems to be correct. But I can now 
see that, in this case, *onSuccess()* and the corresponding service method 
of *rejectBankCheck()* are called twice. Or several times if the user 
doesn't correct the constraint violations after the first call. This means 
that the request calls are collected by the requestcontext.

My first intention was to split this into two steps:

   1. Initialize the requestcontext when the activity starts: 
*request.rejectBankCheck(entity, 
   remarks).to(new Receiver...*
   2. Call request.fire() when the user clicks on the button

This unfortunately isn't possible, since the parameter *remarks* (entered 
by the user) can change between two invocations.

Now my questions:

   1. Is this behaviour a bug or a feature of the request factory? I can't 
   see where this would be useful. If it's a bug, I'll open an issue
   2. Can anyone see a workaround for this?

Problem - Images are not displayed

2012-09-03 Thread Christian Eggert

Hallo,

I am new to GWT so this might be a stupid question. I am trying to 
familiarize myself with GWT and wanted to build a simple UI using the 
UIBinder. For starters I wanted to try a simple layout using the 
DockLayoutPanel with a logo at the top and some images that are supposed to 
be used as navigation on the left. I thought I understood the process (it 
seemed straightforward enough), but for some reason only the images on the 
top are displayed, the images in the left side are not.

All images are saved using the same format (PNG).

Here is the relevant part of the XML (interestingly enough the images are 
displayed when I switch to design mode in Eclipse):

ui:with field=res type=com.gwttest.client.Resources /
 g:DockLayoutPanel

g:north size=200 unit=px
g:HorizontalPanel
g:Image resource={res.imgLogo}/
g:Image resource={res.imgHeading}/
/g:HorizontalPanel
/g:north
g:west size=200 unit=px
g:VerticalPanel
g:Image resource={res.button1}/
g:Image resource={res.button2}/
g:Image resource={res.button3}/
/g:VerticalPanel
/g:west
g:center
g:HTML
Content goes here
/g:HTML
/g:center
/g:DockLayoutPanel

When I look at the javascript console in chrome I can under Resources 
that all images are there. When I dig into the Code under Elements i see 
that the images have been replaced with an image called clear.cache.gif.

Can someone please tell me what I am doing wrong?

Thank you very much

Accessibility and ruler divs...

2012-09-03 Thread dreak

Hi,

I have one small problem... Some widgets contain ruler divs, which looks 
like this:
div style=position: absolute; z-index: -32767; top: -20ex; width:10em; 
height: 10ex;nbsp;/div

When I use JAWS12 (screen reader), and  move through the page with 'DOWN' 
key, it always says 'Blank'.

Would it be possible to add in next release additional attribute to this 
div: aria-hidden='true'? 

Thanks,
dreak.

loginService.loginServer(username,password ,new 
AsyncCallBackCCtLoginUser() { ..

int the server i have:
@Override
public CCtLoginUser loginServer(final String username, String password) 
{.

when we run in all our machines, this work fines but when running on the 
customer machine
we see that the username and passwords   strings are gibrished (or encoded) 
 and login failes,
for example if i send  user123 (username ), abcde (password)  i get in the 
server  username = u199873  password a9343 
the value are the same for the same username and password.

how to get text,value pairs in gwt suggestionBox

2012-09-03 Thread md alamin



i need a autosuggest combobox for an ambiguous list of strings. but everey 
string has an unique id. this id is needed to know what the user has 
selected (send id back to server and do something with it).

how to implement this with the gwt's auto-suggest-comboBox suggestionBox. 
Is there a way to get an List of id-name pairs (like with 
listBox.addItem(String 
name, String value)) into the suggestionBox? probably by overwriting 
suggestionOracle? (how to get the selected id of the selected name?)

or is this usecase better be implemented by another gwt widget?

GWT designer doesn't work in RHEL

2012-09-03 Thread bvt

I'm attempting to using the GWT designer in Eclipse 3.7 on Red Hat 
Enterprise Linux 5.4 (64 bit). I get the following error:

*GWT Designer uses the SWT Browser widget to render the GWT UI. SWT 
Browser requires a compatible xulrunner version installed: it should be 
1.9.1.x or 1.9.2.x version and meet the current environment architecture*

I had a later version of xulrunner installed, so I removed this and 
installed version 1.9.2 instead. I've also tried passing the path to 
xulrunner when starting eclipse and also putting it in eclipse.ini using

-Dorg.eclipse.swt.browser.XULRunnerPath=path to xulrunner 1.9.2

This doesn't work and I get the same error. Has anybody else been able to get 
the GWT designer working in Eclipse on RHEL?

Is this a bug in TabLayoutPanel?

2012-09-03 Thread joelus

Hi, I'm relatively new to GWT so I'm not sure if this is a bug or if I'm 
misunderstanding something.

When I add a widget to a  TabLayoutPanel, if the widget is already attached 
to the TabLayoutPanel, 
it should move the existing widget to the far right.
This is how I understood the javadoc which says of the add(Widget w) method:
Adds a widget to the panel. If the Widget is already attached, it will be 
moved to the right-most index. 
When I try this, however, I get the following error:

com.google.web.bindery.event.shared.UmbrellaException: One or more 
exceptions caught, see full set in UmbrellaException#getCauses
at 
com.google.web.bindery.event.shared.SimpleEventBus.doFire(SimpleEventBus.java:203)

com.google.gwt.user.client.ui.TabLayoutPanel.add(TabLayoutPanel.java:265)

And the existing widget (and header tab) simply disappear from the 
tablayoutpanel.

I had a brief look at the code but wanted to check if this is, in fact, a 
bug or I'm just doing it wrong!

Thanks
Joel

cannot see when this behaviour would be necessary or of any help.


Not a bug.
 


1. Can anyone see a workaround for this?

 Three:

   - either don't use validation on the server-side (either do it on the 
   client-side before calling rejectBankCheck, or inside the rejectBankCheck 
   method on the server-side and use a new RequestContext in the onFailure 
   case)
   - fire() once without the rejectBankCheck to validate the proxies, then 
   if OK create a new RequestContext, edit the proxies, call rejectBankCheck 
   and fire again
   - move the remarks argument to a proxy so you can change it without the 
   need to call rejectBankCheck again

Re: Accessibility and ruler divs...

 Hi,

 I have one small problem... Some widgets contain ruler divs, which looks 
 like this:
 div style=position: absolute; z-index: -32767; top: -20ex; width:10em; 
 height: 10ex;nbsp;/div

 When I use JAWS12 (screen reader), and  move through the page with 'DOWN'

 Would it be possible to add in next release additional attribute to this 
 div: aria-hidden='true'?

Re: fundamental problems with predictive layout

2012-09-03 Thread Andrei

Magnus,

Jens is right: all you need is a simple FlowPanel with a Label and a button 
inside. Set the button style to float: right, set its width (which, I assume, 
is constant), and add a right margin to your label which is wider than the 
button. That's it. Your generated code will be 10 times smaller (layout panels 
produce a lot of HTML), and your pages will reflow much faster.

You don't need to worry about the height: a FlowPanel will expand automatically 
to accommodate its contents. If you want, you can fix its height, or you can 
use min-height and/or max-height CSS rules. You can set a width of the 
FlowPanel in pixels or as percentage of its parent's width, or you can let it 
expand with the content up to a specified maximum. You can allow the content to 
wrap inside the widget, or you can force it to show ellipsis when the label 
gets too long, or you can force a scrollbar, etc. There are a lot of options 
available to you in CSS. I use layout panels only for page structure, and I 
never use HorizontalPanel or VerticalPanel - they offer nothing that cannot be 
easily done with FlowPanels and CSS, while they are less flexible as you have 
discovered.

My advice: when building a layout, forget about widgets. Think how you can do 
it in pure HTML/CSS, ideally without any table elements. Once you do it, the 
choice of widgets becomes obvious.

 Hey,
 we want to use multiple tabs in a GWT Project. Is there a way to implement
 this? We want use ClientStorage for the session tracking. We need more than
 one HTML page because we have a user- /gamemanagement, and for every new
 game thats started we need a new tab. The user can start more than one
 game. TabPanel is maybe a alternative.

 Sorry for my bad english :(

  Hi all,

  

 I am a GWT newbie. I am working on an application in which we have got

 debug them in the hosted mode. I am not able to figure out how will MVC 
 controller return a new view to my GWT application in the hosted mode.

  

 One option is to independently work on each view, compile them and put 
 under the web content of the server. After the development, target 
 integration testing between the pages.

  

 Please let me know if there is a better approach than this one. Any links, 
 pointers, references shall be highly appreciated.

 Hi, anyone here knows http://code.google.com/p/gwt-multipage/ ?

 I have some specific problems with the framework, is there any other GWT

 EntryPoints and load it based on the html request.

 Like: mysite.com/index.html or mysite.com/somethingelse.html will load 
 two separate entry ponts for each.

 Problem with gwt-multipage is that if the access is coming from 
 mysite.com/ (without specifying the html to load) it breaks and 
 sometimes loads random entry points if I am not mistaken.

 Any ideas?

Re: Login form auto-complete and GWT-RPC (or RequestBuilder), a solution!

2012-09-03 Thread Craig Mitchell

I'm a little confused.  The way Tomas showed (above) used to work with 
Autocomplete, however, Chrome decided it wasn't going to play nice with 
that any more.

The only solution I could find was to do a login with a form.  Eg: form 
action=login method=GET.../form

I don't know how to get Autocomplete working in Chrome with GWT RPC, and I 
don't understand what you're talking about with switching to a restful 
approach.

If you (or anyone) can offer a solution not using a form, I'm all ears. 
 As, yes, forms are so 2000s, and I would rather not use them.

Cheers.

Re: fundamental problems with predictive layout


Am Montag, 3. September 2012 16:41:16 UTC+2 schrieb Jens: 

 http://jsfiddle.net/EHCGu/
  
 you can drag the vertical splitter to change the size of the result and 
 the label div fills all the space while the button is float:right. No 
 need to use any onResize() JavaScript as the browser takes care of the 
 size. Maybe you can omit the  div that clears the float:right.

 You should use as much CSS as you can, so you don't have to worry about 
 resizing your widgets. Let the browser do it. 
  

 
Hi Jens,
 
this looks good. I often read about letting the browser do most of the 
layout is much faster.
 
The problem is to integrate this pure HTML/CSS code (your example) into an 
existing environment within GWT, i. e. into a LayoutPanel. The place, where 
the composite widget should be inserted, is a LayoutPanel. I believe that 
whenever I inserted something into a LayoutPanel it gets invisible because 
of size 0. This in turn results in setting the sizes explicitely and so on.
 
So how would one do this (your example) within GWT? Which Panels to use for 
the three DIVs? And how to avoid zero sizes when inserting into the 
LayoutPanel...

Hi Andrei,
 
thanks, I'll change the composite widget to be a FlowPanel, but I am sure 
that it gets 0 sizes when inserted into the LayoutPanel. But it's a 
precondition that the outer environment is a LayoutPanel, because this is 
used - as you mentioned - for the page structure.
 
I understand that you recommend doing the overall page layout using 
LayoutPanels, but doing the small stuff concerning widgets with HTML/CSS? 
Then there must always be a border crossing between the outer layout 
panels and the inner HTML/CSS widgets. And exactly at this border you have 
to insert a widget into a layout panel, right? How do you do this? When I 
do it, the widget gets 0 sizes and I have to hard code the sizes 
explicitely, resulting in ugly code...
