NAME

       SoQtDevice -

       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.

SYNOPSIS

       #include <Inventor/Qt/devices/SoQtDevice.h>

       Inherits SoQtObject.

       Inherited by SoQtKeyboard, and SoQtMouse.

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().
