Searching here and other placed like qtcentre I've seen this problem has come up but can't seem to get it working. I've got a MainWindow widget with a QSplitter which contains two Pane widgets (subclassed from QFrame). Each Pane has a menubar with identical associated QActions/Shortcuts.
I've tried all combinations of ShortcutContexts with setShortcutContext().
WindowShortcut and ApplicationShortcut contexts give the expected "Ambiguous shortcut overload".
While WidgetShortcut and WidgetWithChildrenShortcut both do nothing.
If I activate the menus manually they of course work fine. I've also tried forcing focus on the parent widget with an overloaded enterEvent().
Any ideas?
thanks.

UPDATE:
Adding an addAction(paneSplitAct)
call at the end of Pane::createMenus()
in conjunction with using Qt::WidgetShortcut
context seems to give me what I want.
From what I understand of the docs this is supposed to create a context menu in the widget. I don't appear to be getting one (right mouse click I assume) but that's ok since I don't want one. The eventEvent()
and leaveEvent()
overrides are still needed to set the focus correctly.
