Hi all,
As in rcp platform, it is mandatory to dispose everything you have created whenever possible. As there is nothing like system handlers, do I still have to call dispose method on widgets for example context menu. Can I simply dereference and leave it for garbage collections, as system resource like font, color and image are no longer disposable, which means you don't have to dispose widgets like context menu (even though dispose method is available)?
Thanks in advance.

Hi lsq,
you have to dispose your resources/widgets in RAP too. With current RAP
CVS HEAD (1.4M1) system resource like font, color and image are
disposable if they are not factory created. We have plan to deprecate
some Graphics#getXXX soon. See bug
320928: Deprecate Graphics#getXXX methods?
https://bugs.eclipse.org/bugs/show_bug.cgi?id=320928
This will improve the single-sourcing. You need to dispose your widgets
too, as we have to release (dispose) the corresponding client-side
(javascript) widgets.
HTH,
Ivan
