Object Hierarchy
GObject
+----GInitiallyUnowned
+----GtkObject +----GtkWidget +----GtkContainer
+----GtkBin
+----GtkWindow
The reason this heirarchy is so important is because when you're looking
for functions, properties, and signals for any particular widget, you
need to realize that the functions, properties, and signals of it's
parent objects apply to it as well.
All objects beginning with Gtk are from GTK+. Later, we'll see things
like GladeXML which is part of Libglade or GError which is part of GLib
Devhelp which is likely available as a package for your distribution. Devhelp
allows you to browse and search the API documentation for the libraries
you have installed
