Writing custom widgets

[Tomasz Jankowski <tomcioj gmail com>]

Hello!

I'm going to learn how to create custom widgets using GTK+, but I read
somewhere, that core of GTK+ (way how widgets are managed by GTK+) is going
to be changed in version 3.0, is this true? I read something about realize
and expose methods.

I don't want to spend my time learning some more advanced parts of curren
GTK+ version if it's going to change quite soon.

Thank you for help ;!
