How to implement the “Edit” menu with “Undo”, “Cut”, “Paste” and “Copy”?

Question

Greetings,

for one of my applications I\'m trying to implement an \"Edit\" menu. This menu usually has the standard-entries Undo, Cut, Copy

user285740's solution didn't help me, since I'm using a browser control in my app (CEF or WebKit, doesn't matter).

Why? For browsers, focusWidget() always seems to be NULL, since elements are not widgets. I tried postEvent() to other widgets - didn't work. Adding menu items with QAction::TextHeuristicRole + standard sequences like QKeySequence::Copy didn't do the job, too (I could connect them only to my slots, not to standard slots). Cefclient sample loads a xib file, but it's not an option for me, since Qt creates everything from scratch.

Eventually, I found the solution! Create the same menu items from ObjectiveC++ code. They act like the ones created via QMenuBar, but (!) they can be connected to some real automatic actions like @selector(copy:)

You can find an example here: nsMenuUtilsX::GetStandardEditMenuItem(), just do that from your ObjC++ code.

But, this code doesn't work if you execute it before QApplication::exec(). Qt then "rewrites" the main menu programmatically... How to fix that? Well, maybe I'll add some hack like a QTimer. It doesn't do that if you don't try to add another items via QMenuBar. It's OK now! Qt-independent menu.
