Object Orientation in GTK

[Matthew Ettus <ettus earthlink net>]

Hi.  I'm new to GTK, and X windows programming in general, although I've
done GUI work before.

Anyway, I've been developing an application using GTK.  I've gotten all
the widgets to work and all.  My problem is this --

GTK is (in theory) object oriented.

On the other hand, it seems to encourage the use of global variables. 
In many instances, I see no way of avoiding global variables.

This seems to be in direct conflict.  Am I wrong?  I think I am missing
the basic methodology here.


Could someone point me to a program which is a GOOD example of GTK
programming?

Thanks

Matt
