Hi,
I have a small "file viewer" jface app with a single (main) window. On this
window I have a button, and I'd like its click action to open another copy
of the main window, akin to Window/New Window menu command in the Eclipse
workbench.
My current code to open one window is:
w = MyApplicationWindow()
w.setBlockOnOpen( 1 )
w.open()
Display.getCurrent().dispose()
Calling this code block repeatedly does indeed open new windows...but as
soon as I close one of the windows, all opened windows close and I get an
"Invalid thread access" exception. Not too strange because the code gets
rid of the display; perhaps I should remember the originally opened window
as the "real" main window to "close" and simply "dispose()" newly opened
ones? However what I'd like is workbench behavior in which each workbench
opened via Window/New Window is not dependent on earlier-opened windows for
its lifetime.
Obviously I didn't find anything germane in a web or eclipse-archive search.
Could somebody point me to a sample of how this is done?
Thanx

Errata in original post : once I open multiple windows using the method
outlined earlier, it only if I close the last-opened window that all other
windows close and I get the thread exception.
What I've done since is remove the line
Display.getCurrent().dispose()
This gives me the behavior I want...but I suspect I'm not cleaning up
something.
