GTK+ has its own way of dealing with application defaults, by
using rc files. These can be used to set the colors of just about any
widget, and can also be used to tile pixmaps onto the background of some
23.1. Functions For rc Files
When your application starts, you should include a call
Passing in the filename of your rc file. This
will cause GTK+ to parse this file, and use the style settings for the widget
types defined there.
If you wish to have a special set of widgets that can take on a
different style from others, or any other logical division of widgets, use a
Your newly created widget will be assigned
the name you give. This will allow you to change the
attributes of this widget by name through the rc
If we use a call something like this:
button = gtk.Button("Special Button")
Then this button is given the name "special
button" and may be addressed by name in the rc file as "special
button.GtkButton". [--- Verify ME!]
Section 23.3, “Example rc file” below, sets the
properties of the main window, and lets all children of that main window
inherit the style described by the "main button" style. The code used in the
window = gtk.Window(gtk.WINDOW_TOPLEVEL)
And then the style is defined in the rc file using:
widget "main window.*GtkButton*" style "main_button"
Which sets all the Button (see Chapter 6, The Button Widget widgets in the "main window" to the
"main_buttons" style as defined in the rc file.
As you can see, this is a fairly powerful and flexible system.
Use your imagination as to how best to take advantage of this.
