Re: TabLayoutPanel - Images in Tabs

2012-10-07 Thread Renato Beserra 
I just found the answer!

If it is useful for someone, i just assumed TabBar height would adjust to
bigger images, but i found a doc that explains that the "Layout" components
that require a size, like in the TabLayoutPanel constructor, wont resize
automatically.

Immediate validation of editor field

2012-10-07 Thread RickL 
I have a problem.  I want to force the editor framework to immediately 
validate a field when the user changes its value.  The most obvious and 
simple case is a numeric field.  If the user enters an invalid number, I 
want the error to be reported as soon as the user leaves the field.  I 
don't want to wait for the user to initiate a save to detect that error 
(and other errors like it that don't need to go to the server).

This seems like it should be very easy, but I sure can't seem to find a 
clean solution.

Thanks

Re: Are you happy with GWT?

I haven't regretted it. One of the aspects that haven't been
mentioned, yet, is the ability to use JUnit for testing your GUI.
In short that was one of the main reasons I switched to GWT.
There are many GUI-frameworks out there that for example allow
to create native GUIs for mobile devices from one source-base.
But none of them have something like JUnit that can be as easily
integrated into your production process as it can be done with
GWT (at least if your server side als is Java based or you use
Ant or Maven as deployment tool).

The creation of a GUI working in a browser as well as in a mobile
device might take you a bit longer with GWT but the cost of testing
and debugging with JUnit is way lower in the long run.

TabLayoutPanel - Images in Tabs

2012-10-07 Thread Renato Beserra 
Hi,

I have a TabLayoutPanel, and I would like to add tabs with images.

I tried the following code:

public class AppTabPanel extends TabLayoutPanel {
public AppTabPanel() {
super(2,Unit.EM);
//tab with text
add(new MyCustomPanel(), "Início");

//tab with image
add(new MyOtherPanel(), new Image("images/image1.png"));
}
}

The content is fine, just like the text Tab. But the image get some weird
margins and is cut by  the the "tab bar" div.

I searched the web and the group and tried some CSS hacks, but none was
sucessful.

Can anyone help me do it the right way?

I will try ui:bundle next, but i think that should be possible to code this.


Thanks in advance,

Re: mp3 resources - can they be played from within GWT?

2012-10-07 Thread Chris Lercher 
Yes, GWT includes an Audio class: 
http://google-web-toolkit.googlecode.com/svn/javadoc/2.5/com/google/gwt/media/client/Audio.html

However, not all browsers support all formats, e.g. Firefox doesn't support 
mp3: http://en.wikipedia.org/wiki/HTML5_Audio
So you may have to serve the file in multiple formats. More background on 
HTML5 audio: http://html5doctor.com/html5-audio-the-state-of-play/

GWT Designer - MenuBar

Hello,
i'm using following infrastructure:
Eclipse 4.2.1 
GWT Designer 2.6.0.r42x201206111253

Problem is, that I can't choose MenuBar or MenuItem in GWT Designer Palette.

If I open a class with a menubar, i get following error:

Code splitting not work as expected ?..

2012-10-07 Thread Ed 
Code splitting don't seem to work in my case, please some advice.
All seem to be loaded in the initial download, and I am trying to figure 
out why, which seem to be difficult.

The soyc overal report:
---
Full code size: 1,128,912 Bytes
Initial download size: 1,127,984 Bytes
Left over code: 413 Bytes


For example: I have a controller called MemberLoonControllerDefault that 
should be loaded in a code split.
Looking at the soyc report, it says it's loaded in the initial download, a 
snippet:
---
com.bv.gwt.fresh.declare.inkomen.loon.impl.MemberLoonControllerDefault
Some code is included in the initial fragment ( See why)
---

First: when I click on the "see why" it goes to a none existing page, 
something like:
---
.../compile-report/methodDependencies-initial-B924E6D66110AAF33EFDD758D02DDDB9-0.html#com.bv.gwt.fresh.declare.inkomen.loon.impl.MemberLoonControllerDefault
---

I suppose I have to remove the MD5 code, such that it becomes something 
like this, which works:
---
../compile-report/methodDependencies-initial-0.html#com.bv.gwt.fresh.declare.inkomen.loon.impl.MemberLoonControllerDefault
---

The dependency path snippet: 
---
..loon.impl.LoonControllerBase::LoonControllerBase
..loon.impl.MemberLoonControllerDefault::MemberLoonControllerDefault
..loon.impl.LoonControllerBuilder$MemberLoonControllerBuilder::create
..loon.impl.LoonState$ShowMemberLoonRequest::perform

..EntryPointBase::$doStartApplication
...start.EntryPointBase$1::execute
..EntryPointBase::$onModuleLoad
---

LoonControllerBase is the parent class of the MemberLoonControllerDefault. 
The last part in the Builder is the interesting part:

MemberLoonControllerBuilder(final ControllerLoaderFacade controllerLoader, 
final SimpleAsyncCallback callback,
final int declarationYear) {
super(controllerLoader, callback, declarationYear);
}

public void create(final AsyncCallback callback) {
getLazyLoader().createInCodeSplitDeclareMember1(callback);
}

public MemberLoonController create() {
return LoonFacade.getInstance().createMemberController(getMediator());
}


And the lazy loader (an interface) that is called in the create method, 
performs the actual creation of the controller in a split point:
---
public void createInCodeSplitDeclareMember1(final AsyncCallback 
callback) {
GWT.runAsync(new RunAsyncCallback() {
public void onSuccess() {
callback.onSuccess(null);
}

public void onFailure(final Throwable ex) {
callback.onFailure(ex);
}
});
}


When the callback.onSuccess() is called, it will call the above create() 
method in the Builder.
As you can see, the controller is created through a split point, which also 
clearly shows up in my IDE when following the Call hierarchy path.. Still 
gwt is putting the creation in the initial download which I don't 
understand.

Any idea ?
Might it has something to do with issue 
4412? 
As I the controller is implementing general interfaces that are contained 
in the initial download

Any advice, please ?
- Ed

Re: Are you happy with GWT?

2012-10-07 Thread Yarden Shem Tov 
Yes very much.

Although now I would try also TypeScript (from 
microsoft) if your problems are just runtime bugs and all the dynamic 
nature of JS.

But again, GWT is great for my opinion.
