Gdk: how to remove bit from event mask in Python?

Question

I want to remove the POINTER_MOTION_MASK from my window's events. I tried:

win.set_events(win.get_events() & ~Gdk.EventMask.POINTER_MOTION_MASK)

however, I get this error:

TypeError: Expected a Gdk.EventMask, but got int

How should I remove the bit from the event mask?

I tried this out with *from gi.repository import Gdk* and had no problem. — XORcist, Jan 30 '13 at 17:08
Well, I corrected the question. The point is that `GdkWindow.set_events()` requires a `Gdk.EventMask`. — Charles Brunet, Jan 30 '13 at 17:35

The ~ operator changes the result type:

>>> type(Gdk.EventMask.POINTER_MOTION_MASK)
<class 'gi.repository.Gdk.GdkEventMask'>
>>> type(~Gdk.EventMask.POINTER_MOTION_MASK)
<type 'int'>

So you need to cast the result. I guess this should work:

win.set_events(win.get_events() & (Gdk.EventMask)~Gdk.EventMask.POINTER_MOTION_MASK))
