virtual const SoEvent * | translateEvent (QEvent *event) |
This class manages events generated by the keyboard, including key press and release events (SoKeyboardEvent).
Note :
With Qt, there is no difference between the left and right Window/Meta keys. So SoKeyboardEvent::LEFT_META is returned when either of these keys is pressed.
SoQtKeyboard::SoQtKeyboard | ( | EventMask | mask = SO_QT_ALL_KEYBOARD_EVENTS |
) |
Constructor.
To the constructor, pass which keyboard events you are interested in as a bitwise OR of the following values:
KeyPressMask - Key press messages
KeyReleaseMask - Key release messages
Or simply pass the defined value SO_QT_ALL_KEYBOARD_EVENTS for all keyboard events. The device will only report events of this type for the widget it is enabled on.

Destructor.
virtual void SoQtKeyboard::disable | ( | QWidget * | w, | |
XtEventHandler | f, | |||
XtPointer | data | |||
) | [virtual] |
Disables the device for the passed widget.
Implements SoQtDevice.
virtual void SoQtKeyboard::enable | ( | QWidget * | w, | |
XtEventHandler | f, | |||
XtPointer | data, | |||
void * | unused = NULL | |||
) | [virtual] |
Enables the device for the passed widget. When enabled, the callback function f will be invoked when events occur in the window. data is the clientData which will be passed.
Implements SoQtDevice.
virtual const SoEvent* SoQtKeyboard::translateEvent | ( | QEvent * | event | ) | [virtual] |
Attempts to convert the passed event into an SoEvent.
Returns a pointer to an internal SoEvent object owned by the class. Do not delete this object. If the message was not generated by this device, then NULL is returned.
Implements SoQtDevice.
