Hi, (having used c++ and java before) I've so far ran a few simple
pyglet programs successfully, more or less copied from the
documentation. Prefering to stick to OOP and not to use decorators I
wrote a program with the main window sub-classed, with one 'shape'
class and one 'bag' (for the shapes) class. The trivial program is
below. It runs without errors but I only get a blank black screen.
I'm assuming I've missed something obvious but haven't for the life of
me been able to figure out what that is. Please point me in the right
direction. I'm on linux.
