Hi Thomas,
I am sorry. This is really too much code. Could you please send your two
examples stripped down as much as possible as attachments which directly
work from our demo/test folder. Thanks.

Hello list,
i have a small problem with the QxMenu events. i want to build up my own
context menu dynamical
at runtime with different entrys (for many items with many different
contextmenus).
for this i use the code sniped Version 1 (bellow)
this version doesnt work.
version 2 (bellow too) works fine. i dont understand why.
the only difference is the location of the creation of the QxMenuButton.
version 1: in proto._createWidgets(), executed on class init
version 2: in proto._rebuildMenu(), executed on open/rebuild menu
i need version 1, because in version 2 each time the menu is opend the
QxMenubutton is recreated
(memory leak)
any hints in the right direction?
regards,
Thomas
