Re: help - gtk+2.2.1 and RH8

[Harring Figueiredo <harringf yahoo com>]

  Sorry, but I have not gotten to the theme changes -- ( I am too busy with
other sappas to go into the theme thing.) However, from the little I read on
the GTK site, you will have to initialize some type of Resource (gtk_rc*) to
parse the .gtkrc file and pick the theme from there. I believe that gtk does
that automattically when you call certain API at the begining of you app.

  I will be reading more about that later 'cauz I also want the theme my apps
:P)
