No more handles error [message #438941]

Hi,

I'm using SWT widgets in a standalone application.
When I use my application for a long time, I always have a crash like this :

Exception in thread "main" org.eclipse.swt.SWTError: No more handles.

I dispose all the composites I can dispose.
What can I do to allow new handles dynamically ?

Can someone help me please ?

Thanks.

Have you disposed every :
- GC,
- Font,
- Image,
- Color
- Widgets
- or other SWT objet

that YOU have created ? (do not dispose OS ressources :) ).

Maybe you can try sleak
http://www.eclipse.org/articles/swt-design-2/sleak.htm to watch for memory
leaks.

If not try to use a profiler (hyades ? i never used it so far).

Most probably you are working incorrectly with images, e.g. for
returning action or item images. Please read
http://www.eclipse.org/articles/Article-Using%20Images%20In% 20Eclipse/Using%20Images%20In%20Eclipse.html
for more information about the ImageRegistry class and when/how to
dispose image ressources.

Ciao, Michael.

Thanks a lot for this little program.
It's exactly what I'm searching.

The number of GC's and cursors increase abnormally.
Now I know where the problem comes from, so I'll can try to correct it.

This "sleak" program is really a good tool :-)

Thanks.

Hi,

My images are static objects.

My problem comes from GC's and cursors (I have tried the "sleak" program,
see the Thomas' message).

Thanks.
