It is not included in the main Qt API.<p>The QXtApplication class facilitates the mixing of Xt/Motif and Qt widgets.<p> <p> The QXtApplication and <a href="qxtwidget.html">QXtWidget</a> classes allow old Xt or Motif widgetsto be used in new Qt applications. They also allow Qt widgets tobe used in primarily Xt/Motif applications. The facility is intendedto aid migration from Xt/Motif to the more comfortable Qt system.<hr><h2>Member Function Documentation</h2><h3 class=fn><a name="QXtApplication"></a>QXtApplication::QXtApplication ( int & argc, char ** argv, const char * appclass = 0, XrmOptionDescRec * options = 0, int num_options = 0, const char ** resources = 0 )</h3>Constructs a <a href="qapplication.html">QApplication</a> and initializes the Xt toolkit.The <em>appclass</em>, <em>options</em>, <em>num_options</em>, and <em>resources</em>arguments are passed on to XtAppSetFallbackResources andXtDisplayInitialize.<p> Use this constructor when writing a new Qt application whichneeds to use some existing Xt/Motif widgets.<p> The <em>argc</em> and <em>argv</em> arguments are passed to the QApplicationconstructor.<h3 class=fn><a name="QXtApplication-2"></a>QXtApplication::QXtApplication ( Display * display, HANDLE visual = 0, HANDLE colormap = 0 )</h3>Constructs a <a href="qapplication.html">QApplication</a> from the <em>display</em> of an already-initializedXt application.
