[PySide] QShortcut suppressed by parent widget?

[Tibold Kandrai]

Hey,

 

Sorry forgot to mention to ambiguous shortcuts. :)

Also note that actions added to the widgets will also show up in the widgets context menu.

http://doc.qt.io/qt-4.8/qwidget.html#addAction

 

In general, I prefer using action where ever it is possible. They are very well support all around and give me a nice separation from the visuals.

Ah, much nicer, thanks.
Though I am getting this at the moment:
    QAction::eventFilter: Ambiguous shortcut overload: I

Will investigate further.
Thanks Tibold.

Thanks, but it doesn't seem to make a difference.

The context. In your case IMO it should be QtCore.Qt.WindowShortcut. More here <http://doc.qt.io/qt-4.8/qt.html#ShortcutContext-enum>

Hi all,

below is some test code that shows the problem I'm having, where a shortcut assigned to a child widget will not be triggered once it's part of the main widget.
It works if the widget is called by itself but not when it's part of a parent widget.

I have been searching the internet for an solution but haven't had any luck.

Does anybody know what I'm doing wrong?

Cheers,
frank
