Thanks Russel for your answer, but I'm not able to figure out how my
argument can be the correct one that way... Maybe I'm not as skilled as
I need to realy understand hot this works...
hum seems that your style is in pure Qt, but I'm writing PyQt.
so, maybe an example will be the best way to explain my needs:
I have a popup menu, with entry generated by iteration, each entry is a
submenu, and all sub menus are the same entry.
I can use QAction and its 'activated()' signal when I click on an item
of a sub-menu, but I need to know which of the sub-menu is activated, to
call my slot with the correct argument(s).
I need at lease one argument: an integer that corresponds to the object
that was clicked, so I can determine from witch sub-menu the call is, or
better, a string, like the name of the "sub-menu" item.
I hope you understand my idea, if not, and if you ar OK, we can discuss
this outside of the list ? (to prevent flood with unusefull stuff in the
