Qt Motif Extension

The Qt Motif Extension assists the migration of old Xt and Motif based applications to the more comfortable Qt toolkit. This extension replaces the older Xt/Motif Support Extension included with earlier versions of Qt.

The Qt Motif Extension consists of the following classes:

• QMotif - Provides the basis of the Qt Motif Extension.
• QMotifWidget - Provides the QWidget API for Motif widgets.
• QMotifDialog - Provides the QDialog API for Motif dialogs.
• QXtWidget - The Xt/Motif integration widget from the previous Xt/Motif extension. This class is unsupported and has many known problems and limitations. It is provided only to keep existing source working; it should not be used in new code.
