<h1 align=center>Qt Xt/Motif Support Extension</h1>
<p>
<hr>
<p>
The Qt Xt/Motif Support Extension assists the migration of old
Xt and Motif based code to the more comfortable Qt toolkit.
<p>
<h2>Information</h2>
<p>
The Qt Xt/Motif Extension consists of the following classes:
<ul>
<li><a href=qxtapplication.html>QXtApplication</a> Allows mixing of Xt/Motif and Qt widgets
<li><a href=qxtwidget.html>QXtWidget</a> Base widget for Xt/Motif and Qt combination
</ul>
<p>
<h2>How-to</h2>
<p>
<ol>
<li>Ensure you are using X11R6.
<li>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.
<li>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 program.
<p>
</ol>
<p>
<h2>Example Programs</h2>
<p>
<ul>
<li><a href="mainlyQt-editor-cpp.html">mainlyQt</a>
<li><a href="mainlyXt-editor-cpp.html">mainlyXt</a>
<li><a href="mainlyMotif-editor-cpp.html">mainlyMotif</a>
</ul>
<p>
<h2>Known Bugs</h2>
<p>
This extension is under development. The following problems exist:
<p>
<ul>
<li> The different focus models of Xt, Motif, and Qt interfere.
<li> Clipboard handling between Xt/Motif and Qt does not work properly.
</ul>
