Hi Everyone,
My application modifies an underlying master document. I would like to
include the File Name / Path as part of the Application window title. I
tried to access the ApplicationWorkbenchWindowAdvisor without success. I got
a thread violation.
Can anyone give a tip on how to do this.
Thanks in advance
-Gene

Hi,
why the hell do you have to remember the display in an variable. That's
not needed, a call like
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getShel l().getDisplay().asyncExec(...
would be sufficient in your code!
