Re: [platform-swt-dev] Different Threads and Displays under Linux GTK

Sorry, multiple displays are not yet
implemented on GTK. They were introduced arourd GTK 2.2 and we couldn't
get to them before 3.0.  Also, SWT supports GTK 2.0.6 so we need to
fail gracefully or force everyone to upgrade which most people have done
anyways. Since Eclipse doesn't make use of this feature and some operating
systems do not support it, it was low priorty.  Please enter a bugzilla
request.  Thanks.

Can you structure your application a
different way?  In my experience, multiple displays are not actually
that useful.  About the only use I can imagine is a launcher that
starts a bunch of separate GUI's, each of which has no idea that it is
being launched from a launcher rather than running in it's own process.

Subject	[platform-swt-dev] Different Threads and Displays under Linux GTK

Hi all,
we are having some problems under linux GTK using different Thread's on
different Display's. Basically we want to run a different thread, create
a display for it, then create a shell and make it live on his own, 
separed from the main thread which is running the main Display.

Actually everything works perfectly under Windows XP, but it gives 
IllegalThreadAccessException under linux GTK. After investigating for a
while, we discovered that event destinated to the second shell/display,
arrives in the event loop of the main thread/display, which then locates
the widget and tries to call some methods on it (the first one is the 
"isDisposed()" method), thus causing the exception to be thrown,
and the 
main thread to die.

Is this a known bug? Any idea abut this issue?

Thanks, ciao
Simone Gianni
