[PyKDE] toolbar icons

[V+]

Hi,
I'm writing my first pyqt application, a viewer for hierarchical
databases. At the moment I don't have serious technical problems
with qt but... I don't know where to find a collection of icons for
my toolbar (a silly problem, I suppose). Most of icons I need are
standard (file open/close, go next/previous and so).
The others are more application specific and I suppose I have to design
them by myself.

Anybody can help me?

Thanks in advance.
