Re: Order of instantiation in UI-Binder?

2013-05-08 Thread Kody

OK that would be possible in general, though I require my stuff in the
g:center as it should just take all space that is left in the window. South
would require a fixed size...


2013/5/8 Thad thad.humphr...@gmail.com

 You may have to wait for the entire panel to render before making a call
 on any panel.

 One technique might be to not have a north. Call your current north center
 and put your current center in south. IIRC, you can have multiple souths,
 easts, etc. That might allow everything to layout without intervention.

 Hi,

 I have a SplitLayoutPanel with g:center and g:north.

 The north element depends on the center element, and uses it in the
 contructor after initWidget() has been called.
 Problem: I always get a NullPointerException for the center element used
 in the north element.

 How can I force object creation to be first the center, and then the
 north element? I assume the default is just the other way around?

 Thanks

WebAppCreator failed

2013-05-08 Thread Nigel Smith

Hi,

I'm running Eclipse Juno / WIndows 7 / Java jdk1.7.0_21 / GWT - 2.5.1 / App 
Engine 1.7.7 and I'm getting the Invocation of 
com.google.gwt.user.tools.WebAppCreator failed error message. A quick 
browse offered up 3 solutions as below, each of which I have tried to no 
avail. 

1. Remove classpath - I don't have a classpath set
2. Add gwt-dev.jar  gwt-user.jar to classpath - tried this but it made no 
difference.
3. Workspace folder is read-only - opened up all permissions, but still no 
difference.

As expected from a quick read of the error message, removing GWT from the 
equation solves the problem, but I want GWT!

Also, unclicking Generate sample code solves the problem, but it leaves 
me with concerns that I'm going to come up against other problems down the 
road if this isn't configured properly.

Is there a solution to this, or should I just try and revert to the old 
versions of Eclipse, GWT etc., that I know (used) to work?

Re: Order of instantiation in UI-Binder?

2013-05-08 Thread Jens

SplitLayoutPanel is a DockLayoutPanel and a DockLayoutPanel requirement is
that the center layer is added last. Once the center layer is added you can
not add anything else. Thats because the center panel takes the remaining
space and thus the panel needs to know what is already inside that panel to
calculate the remaining space.

So using stock GWT classes there is no way to change that behavior. You
would need to implement it yourself. Your best bet is probably writing a
custom composite that is backed by a SplitLayoutPanel and provides @UiChild
methods for north/east/south/center. These methods just store the widgets
you add, and in Composite.onLoad() you would build the SplitLayoutPanel
based on the added panels. That way the @UiChild methods can be called in
any order and in onLoad() you can still build the SplitLayoutPanel with the
center panel added last to satisfy DockLayoutPanel requirements.

http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/uibinder/client/UiChild.html

As an alternative try to refactor your code so that you dont need to access
the center panel inside the constructor of the north panel. You could add a
ui:field to the north and center panel and in your UiBinder's Java file
connect both panels *after* binder.createAndBindUi(this) is called. With
your current constructor approach you are trying to connect both panels
*during
the execution* of binder.createAndBindUi(this).

 Many people have had this kind of issue with the installer in 4.2. Most 
 people recommend just starting with a new Eclipse install completely when 
 you hit this, rather than trying to fix your existing install. 

 You may need to export/import your preferences (including external tools,

 of that will come over if you use the same workspace.

 Clearly I do not yet have my mind wrapped around how the events are

  ImageResourceCell, a TextCell, and a TextInputCell. These are 
  displaying in the tree correctly. I have attached an onClick event to 
  the ImageResourceCell that deletes the item from the tree, and that

  However, I'm having a couple of problems with the TextInputCell. 
  First, when I type in the TextInputCell, the space key is ignored - 
  well, it's probably being consumed by something else but the upshot is 
  that when I type a space character, it doesn't appear in the 
  TextInputCell. I thought this might have to do with the SelectionModel

  KeyboardSelectionPolicy.DISABLED and the TreeViewModel to 
  NoSelectionModel and it's still happening.[snip]

Re: mouse over tab (TabLayoutPanel) to select

Instead of using add(Widget, String) to add tabs use add(Widget,Widget).  
Your second argument will be a widget that you have added a mouse over 
handler to that will instruct the TabLayoutPanel to select the appropriate 
tab by calling selectTab(int) or selectTab(Widget).

Have you tried providing, in the java code, the widget that is being added

are calling to get the NPE.
 
Some code would probably go a long way in getting better guidance...

SubmitCompleteEvent.getResults() always returns null

2013-05-08 Thread Robson Braga

Hi guys,

I've a RESTful webservice that returns xml/json and it works properly. 

If I submit a HTML form to that webservice, Firefox and Chrome shows the

input type=email id=email name=email width=10br
input type=password id=password name=password 
width=10br
input type=submit value=Test
/form
/body
/html

Here is my GWT Code:

public void onModuleLoad() {
final FormPanel formPanel = new FormPanel();
formPanel.setEncoding(FormPanel.ENCODING_URLENCODED);
formPanel.setMethod(FormPanel.METHOD_POST);

VerticalPanel verticalPanel = new VerticalPanel();

verticalPanel.add(new Label(Username));
TextBox userid = new TextBox();
userid.setName(email);
verticalPanel.add(userid);

verticalPanel.add(new Label(Password));
PasswordTextBox passwd = new PasswordTextBox();
passwd.setName(password);
verticalPanel.add(passwd);

verticalPanel.add(new Button(Submit, new ClickHandler() {
public void onClick(ClickEvent event) {
formPanel.submit();
}
}));

formPanel.add(verticalPanel);
formPanel.setAction(http://localhost:8080/myWebService/entry;);
formPanel.addSubmitCompleteHandler(new 
FormPanel.SubmitCompleteHandler() {
public void onSubmitComplete(SubmitCompleteEvent event) {
   Window.alert(event.getResults());
}
});

RootPanel.get().add(formPanel);
}

What am I doing wrong? Am I forgetting something? Is there any SOP 
restriction? How do I bypass this issue?

Thanks in advance.

 you hit this, rather than trying to fix your existing install. 

 You may need to export/import your preferences (including external

 but some of that will come over if you use the same workspace.

Re: GWT compilation failed

I had this same issue, and deleting the gwt-unitCache worked for me.
Thanks

 I tried around several things. I think deleting the files in the

You may be able to get some more info or help at the Eclipse WindowBuilder 
forums here: http://www.eclipse.org/forums/index.php/f/214/

Eric Clayberg is usually monitoring those forums and responding to issues. 
There are some posts there that mention Ubuntu.

 Fortunately (I guess) I never found GWT Designer very useful for

Re: Order of instantiation in UI-Binder?

2013-05-08 Thread Kody

OK I see that's not as easy as I thought.
Probably I should refactor my code instead of trying a hacky solution.
Thansk!


2013/5/8 Patrick Tucker tucker...@gmail.com

 Have you tried providing, in the java code, the widget that is being added
 to the center?  That is assuming the widget that you are adding is what you
 are calling to get the NPE.

 Some code would probably go a long way in getting better guidance...

 Hi,

 I have a SplitLayoutPanel with g:center and g:north.

 The north element depends on the center element, and uses it in the
 contructor after initWidget() has been called.
 Problem: I always get a NullPointerException for the center element used
 in the north element.

 How can I force object creation to be first the center, and then the
 north element? I assume the default is just the other way around?

 Thanks

 Hi,

 I have a canvas within the following layout:

AbsolutePanel
 Canvas

 How can I set the coordinateSpace height/width always according to the 
 actual size? How can I get the center size of the dock when creating the 
 canvas?

 I thought I could just walk up the parent tree from the canvas and get the 
 clientwidth, but it is always = 0

 canvas.getElement().getParentElement().getParentElement().getParentElement().getClientWidth()

 What is wrong here?

Re: GWT Image editing

2013-05-08 Thread Kara Marie Rawson

yep, use canvas it will work smoother, especially if you plan on allowing 
the user to drag to position image B at some point. Honestly if you plan 
on not using canvas, atleast use dynamic CSS to handle the image position 
overlay and just stick the images in a simple LayoutContainer. I dont 
believe AbPanel is resize friendly.

 You can also try the Canvas object. That's a neat widget.

Deploying GWT 2.5 on Resin 2.1.17

2013-05-08 Thread alankamp2...@yahoo.com

Hi, 
  I am working on a project for a professor's class and that involves 
converting old jsp pages to GWT code. I have been able to run my 
application in the hosted mode and have also been able to run it on the 
production server which is Resin 2.1.17, without writing any calls to the 
server. I have written some code to make calls to a servlet and it runs 
just fine in hosted mode but on Resin I get messages along the lines of 
404 URL not found. The way I am deploying to the server is to create a 
war file from the folder war created by compiling the project using the 
GWT pluggin in Eclipse. So I am wondering if the gwt.xml file inside the 
war supposed to be enough for Resin to know where to find the servlets or 
are you supposed to make any changes to Resin's configuration to make the 
app work. I apologize if someone gets offended by the lack of information 
in this post. Since I couldn't find any specific information on the web 
about running GWT on Resin, I wasn't sure if anyone uses this configuration 
so I didn't want to post too much. But again, I sincerely apologize again, 
if anyone gets upset over this attitude. I can provide more information 
about the structure of my project and configuration files if someone is 
willing to help out.
Thanks,
Alankar

[gwt-contrib] Re: Re-enabling commits in Gerrit

Just to clarify: does that mean the SVN is now dead? (except for

Anyway, thanks a lot for your work Matthew!

 *tl;dr:* We’re enabling commits in Gerrit, so you’ll be able to land

 We’ve finally gotten things in place internally so we can change the 
 mirroring strategy from “google - subversion - git” to “git - google - 
 subversion”.  (We’re going to keep Subversion around in the interim in case 
 something goes wrong and we need to switch back.)

 As such, we'll soon re-enable +2’s in Gerrit and start allowing commits 
 directly to Git.  Since this is a big change from the current workflow, 
 we’re going to try to take things slowly to start just so we can make sure 
 everything’s working how we envision.  We’ll also work on formalizing some 
 development practices.  As we feel more confident in the process, I expect 
 things will speed up and contributing should be much easier.

 Also, we still plan to re-spin the Git repository in the near future to 
 clean up some accumulated history cruft (e.g., the old plugins binaries). 
  We’ll send out more announcements about that once we’re prepared to make 
 that change.

 Thanks for your patience!
