3 * Many applications can't use CTK+ widgets, for a variety of reasons,
4 * but still want their user interface to appear integrated with the
5 * rest of the desktop, and follow CTK+ themes. This demo shows how to
6 * use CtkStyleContext and the ctk_render_ APIs to achieve this.
7 *
8 * Note that this is a very simple, non-interactive example.
