elementary/ctxpopup - [E-devel] [PATCH] [Elementary] Fix memory leak and callback function in ctxpopup
Hello everyone, There are two issues with ctxpopup: - Memory leak: Elm_Ctxpopup_Item is used but not deleted. - Incorrect callback function: returned object and event_info are list object and item (should be ctxpopup object and item). I would like to send a patch to fix above issues. I also provide the patch for backporting. Please review them. Best Regards, Thiep Signed-Off-By: Theip Ha<thiep.ha@samsung.com> SVN revision: 82968
