## NAME

## SYNOPSIS

This class is part of the **Qt Motif Extension**.

`#include <qmotif.h>`

Inherits QEventLoop.

### Public Members

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

### Static Public Members

**Display \* x11Display ()**\

## 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.
