[clug] Building a simple UI with pygame, keystrokes and a window focus problem

[Francis Whittle]

I don't have any experience with pygame, but if you're trying to do this
inside an X11 process, the keyboard focus is generally determined by the
window manager.  X11 clients can theoretically prevent other
applications from getting focus by "grabbing" the input system.  Pygame
supposedly has a facility for this in the event module in the form of
the set_grab method. See
http://www.pygame.org/ctypes/pygame-api/pygame.event-module.html .   I
say theoretically because X11 and/or the WM can prevent it from working
properly.

GStreamer developers would probably tell you to "just write a photobooth
application in python, it's easy"
