Leo Body Widget / Events Question

[Adrian]

Hello,

After some code searching (Use the Source Luke), I determined how to finally hook in my own kepressevent handlers for the body pane in a reliable fashion.  But I had to put in a hack in the EventFilter system, to pass on every key press event to global dispatcher that I created.  Otherwise, no matter what I did, I would not get consistently called event handlers.

Sure it works, but I am not sure if there is a way for me to reliably capture keypress events in the body pane without this hack?

Here is what I did:

In the eventFilter method, of the LeoQtEventFilter class:

        if self.keyIsActive:
            #2017-07-04: change made by me under this comment
            try:
                g.user_dict['my_key_dispatcher'](event)
            except Exception as e:
                g.red(e)
                g.red("My Key Dispatcher has not been instantiated, qt_events.py")
            #--

g.user_dict['my_key_dispatcher'] is a function defined at startup in myLeoSettings.  It runs through a list of handlers I can add or remove at anytime.

Yes, it works, but ugly.

Is there a non-hack way to get all key press events from the body pane?

Thanks,

Adrian

​Yes and no.

Yes: could assign your own Qt event filter to the body widget.

No: By default, your custom event filter would have to make sure it does what the default event filter does.
