In my case, I have a chemical periodic table made with GTK buttons, each one representing a chemical element, with its default color. Users can change these chemical element default colors directly from the interface or from XML config files:

I asked a question and then replied myself in this post: http://stackoverflow.com/questions/8952679/gtkmm-3-button-background-color-change You have to use a CSS file (a working example in my code) and import from code to override the gtk3 theme that you are using on your distribution. Cheers, Giuseppe.I had a similar problem and it seems that even with Priority = Application the default theme is overriding "override_background_color()". I would like to know if this is a bug as I wasted several hours trying to find the work around and ended up having to use the css method with the applicable config from the default theme which seems a little excessive when a 1 liner in code should be possible.On Sun, Aug 26, 2012 at 1:44 PM, Rudra Banerjee <bnrj.ru...@yahoo.com>wrote:I will be grateful if someone please show me the way.

I am posting the complete minimal code(60 line only) for yourreference.I have seen that the gtk_widget_modify_bg is deprecated in gtk 3 so I tried the suggested method with gtk_widget_override_background_colorbutthere it seems that declaration of GdkColor colorRed2 = {0x0000,65535,29555, 24158} has changed to something like GdkRGBA.
