Detailed Description

The SoXtKeyboard class is the keyboard input device abstraction.

The SoXtKeyboard class is the glue between native keyboard handling and keyboard interaction with the Inventor scenegraph.

All components derived from the SoXtRenderArea have got an SoXtKeyboard device attached by default.

Member Enumeration Documentation

Events

enum SoXtKeyboard::Events

Enumeration over supported event types.

Enumerator
KEY_PRESS	Maskbit for a keyboard button press event.
KEY_RELEASE	Maskbit for a keyboard button release event.
ALL_EVENTS	Combined bitmask for all possible events.

Constructor & Destructor Documentation

SoXtKeyboard()

SoXtKeyboard::SoXtKeyboard

(

int

mask = ALL_EVENTS

)

Constructor. The mask specifies which keyboard-related events to handle. Others will just be ignored.

~SoXtKeyboard()

SoXtKeyboard::~SoXtKeyboard ( void  )

virtual

Destructor.

Member Function Documentation

enable()

void SoXtKeyboard::enable ( Widget  widget, SoXtEventHandler *  handler, void *  closure  )

virtual

This method will enable the device for the widget.

handler is invoked with the closure argument when an event occur in widget.

Implements SoXtDevice.

disable()

void SoXtKeyboard::disable ( Widget  widget, SoXtEventHandler *  handler, void *  closure  )

virtual

This method will disable the handler for the device.

Implements SoXtDevice.

translateEvent()

const SoEvent * SoXtKeyboard::translateEvent ( XAnyEvent *  event )

virtual

This method translates from native events to Open Inventor SoEvent events.

Implements SoXtDevice.
