Member Function Documentation

§ areGadgetsActive()

IlBoolean IlvATInteractor::areGadgetsActive ( ) const

Indicates whether events occurring in a gadget are dispatched to the gadget.

This method affects the way an event occurring in a gadget contained in the annotated text is dispatched. If the method returns IlFalse, the event is not sent to the gadget and IlvATInteractor::handleEvent() is called. Otherwise, the event is dispatched to the gadget by means of a call to IlvGadget::handleEvent(); if this call returns IlFalse, IlvATInteractor::handleEvent() is called.

Returns: IlTrue if the event must be dispatched to the gadget.

§ handleEvent()

virtual IlBoolean IlvATInteractor::handleEvent	(	IlvATZone *	zone,
		IlvEvent &	event
	)

pure virtual

Handles user events that occur over a text zone.

Called by the annotated text when an event occurs on an IlvATZone. The interactor is attached to either zone or, if zone does not have interactor attached to it, to the IlvATPalette of the annotated text.

Parameters

zone	The text zone where the event occurred.
event	The event.

Returns: IlTrue if the event is consumed by the interactor.

§ setGadgetsActive()

void IlvATInteractor::setGadgetsActive ( IlBoolean active )

Specifies whether events occurring in a gadget must be dispatched to the gadget.

Defines what is done with an event if this event is located on an IlvGadget.
