Re: Problem Updating View Programmatically
Thanks for responding.
Thanks in advance for any help.
Since I have posed two questions at once, if it's all the same to
everyone, I'd like to focus on my issue with canvas first.
What's goes wrong when I try to make a Canvas part of a view using
uibinder?
If I code something like this, I see a Canvas with the appropriate
stuff drawn on it. But (see below)...
public void onModuleLoad() {
SimpleLayoutPanel pnl = new SimpleLayoutPanel();
Canvas cvs = Canvas.createIfSupported();
pnl.add(cvs);
RootLayoutPanel.get().add(pnl);
Context2d ctx = cvs.getContext2d();
int w = cvs.getCoordinateSpaceWidth();
int h = cvs.getCoordinateSpaceHeight();
ctx.setFillStyle("#d53747");
ctx.moveTo(0, 0);
ctx.lineTo(w, h);
ctx.beginPath();
ctx.arc(w/2, h/2, 9, 0, Math.PI * 2.0, true);
ctx.closePath();
ctx.fillText("Yay!!", w/2, h/2 + 20);
ctx.fill();
}
if I code something like this:
(1) Here's the uibinder declaration.
(2) Here's the corresponding field in the view class:
@UiField
Canvas cvs;
(3) And of course, Canvas needs this:
@UiFactory public Canvas getCvs() {
return Canvas.createIfSupported();
}
Then do the same drawing, nothing appears on the Canvas. It remains
blank. It has size. Nothing is null. No errors are thrown.
Context2d ctx = vw.getCtx();
int w = vw.getCvs().getCoordinateSpaceWidth();
int h = vw.getCvs().getCoordinateSpaceHeight();
ctx.setFillStyle("#d53747");
ctx.beginPath();
ctx.arc(10, 10, 9, 0, Math.PI * 2.0, true);
ctx.closePath();
ctx.fillText("Yay!!", w/2, h/2 + 10);
ctx.fill();

Problem Updating View Programmatically
All,
I am attempting to do something that must be very common, but I can't
get it to work. I place either a canvas or a TextBox on the screen
and change it programmatically and my changes don't show up on the
screen.
I am using uibinder. If I give say, my TextBox an initial value
XXX this value is displayed on the screen when
I run the app. But if I attempt to change the value by calling
textBox.setText("YYY") from the program. The display continues to
show the original XXX. It's as if I need to do some kind of refresh.
A similar thing is happening with Canvas. I create the Canvas in the
program, add it to a SimpleLayoutPanel, and draw on it--nothing
appears.
All this is consistent throughout my app. Any data values I declare
in the uibinder file. appear just fine, but any values is set from the
program have no effect.
Clearly, I am doing something wrong, but what? Do I need to repaint
somehow?
Thanks

Serialization for RPC Not Working as Expected
All,
I am getting some behavior I can't understand wrt a class I am
returning via RPC serialization.
My question is, How can I troubleshoot this?
First a bit of code:
public class Setup implements IsSerializable {
private static final long serialVersionUID =
private List dispositions;
private List uploads;
private List
GWT eclipse plug manual install?
All, I have looked and I cannot find a link from where I can download GWT 1.6 for a manual install. (I could also be blind.) Is there such a thing, or is it update site or nothing? I am trying to upgrade to GWT 1.6. When I attempt to do so using the update site, It throws an error (see below). Has anyone seen this kind of thing before? I have successfully upgraded two other machines. It's only this third box that gives me trouble. All three machines have eclipse 3.4 on WinXP. An error occurred while collecting items to be installed Error closing the output stream for org.eclipse.datatools.sqldevtools.data.feature/ org.eclipse.update.feature/1.6.2.v200810071455-3109oA55V589K5QA5 on repository file:/C:/Program Files/eclipse-ganymede/.

Re: Deploying GWT applications on OSGi Equinox
Ian, Have seen the article "Embedding an HTTP server in Equinox"? If not give it a read and we can continue. It explains how to do without war file. http://www.eclipse.org/equinox/server/http_in_equinox.php On Apr 8, 2:41 am, lan wrote: > Yes I'm absolutely interested. > I don't understand how you don't use a war file. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Deploying GWT applications on OSGi Equinox
I too am in the midst of deploying GWT to equinox. It's working but I don't use war files. I put my GWT code into a bundle, which means using extension points to specify my servlets in lieu of doing so in web.xml. If you're interested in discussing this further let me know.
