Dear Filipe!
I want to add a set of customized items instad of the stock icons. How its the better and eficient way to do it? Is setting the item by the file name? create pixbufs ? I don't know how this work, is there some toturial that explains the ways to do it and the differences between them?
Are you trying to change the icons displayed in the window bars or the icons on widgets, like OK buttons?
