NEWT blocks SWT Thread

hey all,

I have an eclipse RCP application with JOGL. I tried to use the NEWT + NewtSWTCanvas but I had the problem that it somehow blocks the SWT Dispatch thread.

To be more precise:

During rendering I do schedule some Display.asyncExec tasks, but they are never executed. However if I switch to a non NEWT window, all tasks are executes. So the NEWT windows blocks somehow the SWT Dispatch thread.

tested with 2.0-rc11
Win7-64Bit

What can I do?

But your report is different, i.e. non execution of the async tasks
which I actually have experienced as well on the Windows platform
with SWT version 4.3.0 M3.

Pls file a new bug report so we can track this issue properly.

Wait until I have fixed it :)

ok I will test the next autobuild and if the error still occurs I will create a bug report

thx

ok

I have tested the autobuild from 20121127 but it didn't help.

I created a little test setup under :

git@bitbucket.org:sgratzl/jogltest.git

containing a project: testjogl3

the project contains to main classes which should perform the same thing: showing a message box when the context is initialized.

the first  uses the SWT GLcanvas, the other one NEWT -> in the first case the message box will be shown in the other one, it won't. In addition after I close the window it tries to now open the message box but as the display is already disposed it will raise an error
