Hi,
As long as I correctly understood, there is no connection between
GarbageCollector and <EclipseObject>.dispose() method (dispose() == just a
function name).
dispose() Method is either automatically called when Display.dispose() is
run (I think on Display.close()), either is the User responsabilty to do
it.
SWT Image is a Object among those belonging to User responsability to
Dispose it (see eclipse doc, there is clear written if a Object is
disposed when at parent disposing time).
If you want "automatically" Image disposing, use jface ImageRegistry: take
a look there is just a listener of Display when is disposing, in order to
release Images registered. Also for Colors you have such a help class, for
other resources you have to build it alone (Cursor I think).
Regards,
Tiberiu
