Handling Edit Menu Items (Cut, Copy, Paste, etc.) with multiple widgets

[gkroeger]

I have an application in which the main windows have two widgets than can receive edit actions, depending on where the focus is. One is a QPlainTextEdit, the other is a custom window displaying waveforms. I am wondering what the "best" or "official" way to deal with this is?

I can implement an action handler in the main window that directs the actions to the widget with current focus. I would also have to handle enabling or disabling the associated menu item depending on whether the widget with focus has any selection (QPlainText Edit provides a signal for this).

Is there a better way to do this, perhaps entirely with signals and slots directly to the widgets?

Any suggestions or examples would be very helpful.
