themes on linux and wx

I wonder how does wxPython get use of styles installed on my box. I did some changes and I got Gtk-Warnings about being unable to loads module_path: qtpixmap. I googled out that solutions for this would be deleting ~/.gtkrc which I did. The problem is solved, but now I got flatly looking wx apps and demo of course too, and even some of the demo stuff doesn't work properly (FileReplaceDialog, TextCtrl show only partially).
Someone could point me to or help how to get wxPython load in some of the theme I have? I tried to copy gtkrc (exactly from gtk-2.0 dir) from themes dir to my home dir and even set the module path, but nothing.
Thanks
