GtkEditor is a source code editor widget for GTK+. It is currently used, in one version or another, in several GTK+/GNOME applications, including gIDE, VDKBuilder, and GXEdit. The gtkeditor widget sub-classes the gtktext widget, and after initialization, the editor widget can be treated as the usual text widget, and all source-code editing features are taken care of by the widget itself. The behaviour of the editor is decided by dynamic libraries loaded during initialization of the widget. These libraries can be hand-coded or (in the future) created using tools supplied with GtkEditor.
