Eclipse UI fails to repaint after processing a click on my view [message #323931]

Hi!

I have a view which contains an org.eclipse.draw2d.FigureCanvas with
several figures in it. Those figures listen to mouse clicks. Inside
the mousePressed() method I sometimes open windows like
MessageDialogs etc. If a dialog was opened it may happen that the
complete Eclipse UI gets white or just the toolbars and my view get
white. I think Eclipse wants to redraw everything but fails to do
so. Is there a method which redraws the whole Eclipse UI? Or is
there something fundamentally wrong with my code (opening Dialogs
inside the mousePressed method)?

Any suggestions?

Nicolai,

If you open a blocking dialog, that likely means your mouse event
doesn't finish processing until the dialog is completed and that's
perhaps not a good thing. Consider using Display.asyncExec to open your
dialog a little bit later and so that the mouse event processing can
return to the caller...

Thanks a lot, Ed!

That did it.

For those searching the archives here is a very interesting
article related to the problem I had:
