Detailed Description
       The SoQtDevice class is the base class for the translation devices.

       The SoQt device classes provide glue functionality for translating native GUI events from the underlying toolkit to Inventor scenegraph
       SoEvent events.

       The device classes are mainly of interest to application programmers when writing extensions for new types of devices, and seldom in other
       contexts -- so they can most often be ignored.

Constructor &; Destructor Documentation
   SoQtDevice::~SoQtDevice () [virtual] Public virtual destructor.
   SoQtDevice::SoQtDevice (void) [protected] Constructor. Protected to only enable invocation from derived device classes.
Member Function Documentation
   void SoQtDevice::enable (QWidget *widget, SoQtEventHandler *handler, void *closure) [pure virtual] This method will enable the device for the
       widget.
       handler is invoked with the closure argument when an event occur in widget.

       Implemented in SoQtMouse, and SoQtKeyboard.

       Referenced by SoQtRenderArea::buildWidget(), and SoQtRenderArea::registerDevice().

   void SoQtDevice::disable (QWidget *widget, SoQtEventHandler *handler, void *closure) [pure virtual] This method will disable the handler for
       the device.
       Implemented in SoQtMouse, and SoQtKeyboard.

       Referenced by SoQtRenderArea::unregisterDevice().

   const SoEvent * SoQtDevice::translateEvent (QEvent *event) [pure virtual] This method translates from native events to Open Inventor SoEvent
       events.
       Implemented in SoQtMouse, and SoQtKeyboard.

   void SoQtDevice::setWindowSize (const SbVec2ssize) This method sets the cached size of the window the device is 'attached' to.
       Referenced by SoQtRenderArea::registerDevice().

   SbVec2s SoQtDevice::getWindowSize (void) const This method returns the cached window size.
   void SoQtDevice::initClasses (void) [static] This function initializes the type system for all the SoQt device classes. It is called indirectly
       when calling SoQt::init(), so the application programmer doesn't have to bother with it.
       References SoQtObject::initClass().

       Referenced by SoQtObject::init().

   void SoQtDevice::setEventPosition (SoEvent *event, intx, inty) const [protected] This method fills in the position information of event,
       translating the coordinates into the correct coordinate system.
       Referenced by SoQtKeyboard::translateEvent(), and SoQtMouse::translateEvent().

   SbVec2s SoQtDevice::getLastEventPosition (void) [static, protected] Returns last event position that was set with
       SoQtDevice::setEventPosition().
       Referenced by SoQtKeyboard::translateEvent().

   void SoQtDevice::addEventHandler (QWidget *widget, SoQtEventHandler *handler, void *closure) [protected] Stores an event handler for the
       widget, which can later be invoked with SoQtDevice::invokeHandlers(). Used by extension device types.
   void SoQtDevice::removeEventHandler (QWidget *widget, SoQtEventHandler *handler, void *closure) [protected] Remove a handler registered with
       SoQtDevice::addEventHandler().
   void SoQtDevice::invokeHandlers (QEvent *event) [protected] Invoke all handlers registered with SoQtDevice::addEventHandler().
