In GTK+ 2.16, a number of previously abstract widget classes were made instantiable (in the cause of introducing the GtkOrientable interface). Making a class instantiable is a lot like introducing a new class, and gives us the chance to reconsider the defaults for their properties.

Here is a fragment of the class hierarchy, with the newly instantiable classes in bold:

  • GtkWidget

    • GtkRuler

      • GtkHRuler
      • GtkVRuler
    • GtkRange

      • GtkScale

        • GtkHScale
        • GtkVScale
      • GtkScrollbar

        • GtkHScrollbar
        • GtkVScrollbar
    • GtkSeparator

      • GtkHSeparator
      • GtkVSeparator
    • GtkContainer

      • GtkPaned

        • GtkHPaned
        • GtkVPaned
      • GtkBox

        • GtkHBox
        • GtkVBox
        • GtkButtonBox

          • GtkHButtonBox
          • GtkVButtonBox
