How to Obtain Display* In PySide

[paepcke]

I am trying to connect a SpacePilot to a PySide application.
For this I need to communicate my application's Window,
and Display pointer to another process. Subsequently I
need to receive X11 events.

I use x11info's appRootWindow () to get the Window. But
how to get the Display pointer? The 'see also' sections of
the manual mention a display() method, but when I try to
call it on an x11info instance I get an error that display is
not an attribute for that class.

I used ctype to get a Display pointer via libX11.XOpenDisplay(None);
But I then do not subsequently receive X11events into x11FilterEvent
method. I only receive device button pushes via the regular QEvent mechanism.

I understand from old threads elsewhere that there might be multiple
reasons for not seeing X11 events. But my first guess is that the
X11 events are going to the wrong Display. Therefore the question.

Thank you for any help.
