Qt Xt/Motif Support Extension

The Qt Xt/Motif Support Extension assists the migration of old Xt and Motif based code to the more comfortable Qt toolkit.

Information

The Qt Xt/Motif Extension consists of the following classes:

• QXtApplication allows mixing of Xt/Motif and Qt widgets.
• QXtWidget is the base widget for Xt/Motif and Qt combination.

How-to

1. Ensure you are using X11R6.

2. Ensure the programs you wish to port are compilable by a C++ compiler, or at least that this is the case for the parts which need migration.

3. Decide whether you are writing a new Qt application reusing old Xt widgets, or introducing new Qt widgets into an existing Xt/Motif application. See the corresponding example programs.

Known Bugs

This extension is under development. The following problems exist:

• The different focus models of Xt, Motif and Qt interfere.
• Clipboard handling between Xt/Motif and Qt does not work properly.
