Detailed Description

This class is defined in the Qt Motif Extension, which can be found in the qt/extensions directory. It is not included in the main Qt API.

The QMotif class provides the basis of the Motif Extension.

QMotif only provides a few public functions, but it is at the heart of the integration. QMotif is responsible for initializing the Xt toolkit and the Xt application context. It does not open a connection to the X server, that is done by QApplication.

The only member function in QMotif that depends on an X server connection is QMotif::initialize(). QMotif must be created before QApplication.

Example usage of QMotif and QApplication:

    static char *resources[] = {
        ...
    };

    int main(int argc, char **argv)
    {
        QMotif integrator( "AppClass" );
        XtAppSetFallbackResources( integrator.applicationContext(),
                                   resources );
        QApplication app( argc, argv );

        ...

        return app.exec();
    }

Member Function Documentation

QMotif::QMotif ( const char * applicationClass, XtAppContext context = NULL, XrmOptionDescRec * options = 0, int numOptions = 0 )

Creates QMotif, which allows Qt and Xt/Motif integration.

If context is 0, QMotif creates a default application context itself. The context is accessible through applicationContext().

All arguments passed to this function (applicationClass, options and numOptions) are used to call XtDisplayInitialize() after QApplication has been constructed.

QMotif::~QMotif ()

Destroys QMotif.

XtAppContext QMotif::applicationContext () const

Returns the application context.

Display * QMotif::x11Display () `[static]`

Returns the X11 display connection used by the Qt Motif Extension.
