QT uses a slightly different approach to theming then GTK does. Basically, in
KDE it breaks up functionality into two parts, a class called QStyle that does
the actual physical drawing, and a group of pixmaps (the theme for the style).

This has two distinct advantages. First, in KDE it will be possible to use a
group of pixmaps (say a marble theme or a gradient theme) with any widget
style (say Platinum or Next) with no changes being made to either. I am doing a
class called KStyleHelper with helps with the fine details such as whether a
pixmap should be tiled for one style while scaled for the next,
specialized caching, etc...

The second is that you can literally do anything you want in the style's
drawing methods. This includes making a GTK theme parser if someone wishes to
write it. While I am doing some KDE style integration and themes, I do not intend to write
the GTK theme engine. If someone wishes to do so, please feel free to email me
and I would be glad to let you know what the status of the KDE code is and how
to best use it.

BTW: You will need both KDE1.2 from CVS and QT2.0 beta both running and
operational.
