Member Function Documentation

◆ keyPressed()

boolean keyPressed ( [in] com::sun::star::awt::KeyEvent  aEvent)

This function is called by the broadcaster, an com::sun::star::awt::XExtendedToolkit for instance, after a key has been pressed but before it is released.

The return value decides about whether other handlers will be called and a handling by the broadcaster will take place.

Consume the event if the action performed by the implementation is mutually exclusive with the default action of the broadcaster or, when known, with that of other handlers.

Consuming this event does not prevent the pending key-release event from being broadcasted.

Parameters
aEventThe key event informs about the pressed key.
Returns
When FALSE is returned the other handlers are called and a following handling of the event by the broadcaster takes place. Otherwise, when TRUE is returned, no other handler will be called and the broadcaster will take no further actions regarding the event.

◆ keyReleased()

boolean keyReleased ( [in] com::sun::star::awt::KeyEvent  aEvent)

This function is called by the broadcaster, an com::sun::star::awt::XExtendedToolkit for instance, after a key has been pressed and released.

The return value decides about whether other handlers will be called and a handling by the broadcaster will take place.

Consume the event if the action performed by the implementation is mutually exclusive with the default action of the broadcaster or, when known, with that of other handlers.

Parameters
aEventThe key event informs about the pressed key.
Returns
When FALSE is returned the other handlers are called and a following handling of the event by the broadcaster takes place. Otherwise, when TRUE is returned, no other handler will be called and the broadcaster will take no further actions regarding the event.
