Inheritance diagram for SoQtDevice:
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.

class | SoQtDeviceP |
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, SoQtKeyboard, and SoQtSpaceball.
void SoQtDevice::disable | ( | QWidget * | widget, | |
SoQtEventHandler * | handler, | |||
void * | closure | |||
) | [pure virtual] |
This method will disable the handler for the device.
Implemented in SoQtMouse, SoQtKeyboard, and SoQtSpaceball.
const SoEvent * SoQtDevice::translateEvent | ( | QEvent * | event | ) | [pure virtual] |
This method translates from native events to Open Inventor SoEvent events.
Implemented in SoQtMouse, SoQtKeyboard, and SoQtSpaceball.
void SoQtDevice::setWindowSize | ( | const SbVec2s | size | ) |
This method sets the cached size of the window the device is "attached" to.
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.
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().
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().
