SoQtDevice::~SoQtDevice () [virtual]¶

Public virtual destructor.

SoQtDevice::SoQtDevice (void) [protected]¶

Constructor. Protected to only enable invocation from derived device classes.

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::registerDevice(), and SoQtRenderArea::widgetChanged().

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 SbVec2s size)¶

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, int x, int y) const [protected]¶

This method fills in the position information of event, translating the coordinates into the correct coordinate system.

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().
