Even though the Gnome theme engine creates some
good looking interfaces by default based upon the current system theme
settings, its still possible to override default values in a way not
usually recommended. This is achieved using customized resource files.
When Gtk is first initialised by the Gnocl package, the files looked for will be <SYSCONFDIR>/gtk-2.0/gtkrc and .gtkrc-2.0 in the users home directory.
Whilst the implementation of the loading of resource files is
minimal at the present time, this mechanism allows a high level of
introspection. The following is an example of a simple customized
resource file employed in the gnocl demo script, test_resourceFile.tcl.
First the before and after screen shots.
And the resource file that made the difference.
The Gtk+ online documentation provided more on the construction of resource files.
