default value in a list

[TB]

Hi,

Is there an elegant way to assign to a list from a list of unknown
size?  For example, how could you do something like:

>>>  a, b, c = (line.split(':'))
if line could have less than three fields?

Thanks,
TB

Thanks very much for all the responses.  They were useful to me and
I'll probably refer back to them again in the future.

Using PyQT and OpenGL

[Peter TB Brett]

Hi folks,

Although the PyQt documentation indicates that QGLWidget & friends have
been ported to Python for the PyQt bindings, I'm not entirely sure what's
necessary to make the normal OpenGL/GLUT interface available.

Does PyQt work okay with PyOpenGL?  Or is a more complicated workaround
needed?

If anyone has experience with working with Python/Qt/OpenGL and can offer
any advice I'd much appreciate it.

Thanks,

Peter

Detecting window focus events in PyGTK

[Peter TB Brett]

Hi folks,

I'm currently trying to work out how to detect when a PyGTK window
receives the focus from the window manager -- I assume that it must
receive some kind of X event, but I can't work out which signal it
generates. Searching around the subject on the web doesn't seem to pull up
anything useful.

I tried the "focus" signal, but that doesn't work the way I'd like it
to. For example, the following code only prints the message "Received
focus!" once (immediately after startup) even when it _isn't_ the active
window.


#!/usr/bin/env python
import pygtk
pygtk.require('2.0')

import gtk

def event_focus(widget, direction):
print "Received focus!"

window = gtk.Window()
window.set_size_request(100, 100)
window.connect("focus", event_focus)
window.show_all()
gtk.main()


I suspect that I'm hacking in the wrong place, so any hints or tips much
appreciated!

Thanks,

Peter
