And a new question...
In my application (a working plugin) I changed something in an open editor.
I can cast this opened editor to EditorPart and want to use the
doSave(IprogressMonitor monitor) method
I did the following:
IProgressMonitor monitor = null;
try {
if (monitor == null)
monitor = new NullProgressMonitor();
monitor.beginTask("Save content...", 1);
((EditorPart) editorPart).doSave(monitor);
monitor.worked(1);
} finally {
monitor.done();
}
But I get the following exception:
Exception in thread "main" org.eclipse.swt.SWTException: Unspecified error
And I found out the following:
org.eclipse.swt.SWTException: Invalid thread access
Now what? Am I using an existing IPgrogressMonitor? If yes - were do I get
it?
Thanx before

R4ID,
You can't do GUI operations on a background thread. Have a look at
Display.asyncExec. You might find ProgressMonitorDialog useful. When
you get exceptions and want to ask questions about them, it's good to
get the stack trace from the Error Log view and include that in your
question.

Okay - thanx for fast reply...
I extended my app in the following manner:
1.)
public class SaveEditorJob implements IRunnableWithProgress {...}
2.)
SaveEditorJob job = new SaveEditorJob((EditorPart) editor);
3.)
ProgressMonitorDialog dlg = new ProgressMonitorDialog(activeShell);
dlg.run(false, false, job);
Beng - active Shell???
I tried the following:
IWorkbench workbench = PlatformUI.getWorkbench();
Shell[] shells = workbench.getDisplay().getShells();
=> Invalid Thread access (SWT thingy)
Then I tried:
Shell activeShell = Display.getDefault().getActiveShell();
=> Invalid Thread access (SWT thingy)
Now what?

R4ID,
I don't think you've read about asycExec yet. It still sounds like you
are running this on a background thread.

mea maxima culpa...
You said it - I googled and found the other solution. But now I make a new
runnable annonymous class which will force the doSave.
I use the NullProgressMonitor in this one
and then I pass the runnable to the Display.getDefault().asyncExe(job) =>
and it works...
Fine - thanx ;)
