Constructor & Destructor Documentation

VRS::Selector::Selector	(	InputEvent::Button	button,
		InputEvent::Modifier	must_modifier = InputEvent::NoModifier,
		InputEvent::Modifier	must_not_modifier = InputEvent::NoModifier,
		RayRequest *	startRequest = (RayRequest *) 0,
		RayRequest *	motionRequest = (RayRequest *) 0,
		RayRequest *	endRequest = (RayRequest *) 0,
		Callback *	startCallback = (Callback *) 0,
		Callback *	motionCallback = (Callback *) 0,
		Callback *	endCallback = (Callback *) 0
	)

Performs the ray request during a mouse interaction. The results of ray requests are stored in the ray request objects.

These methods implements the concrete manipulator functionality. They are overloaded by subclasses. `dragStart' is called if an event of type `ButtonEvent` is received which matches the button condition. `dragMotion' is called if the interaction has been started already and an `MotionEvent' has been received which matches the modifier conditions. `dragEnd' is called if the interaction has been started already and an event of type `ButtonEvent' has been received which matches the button condition. The return value specifies the redrawing code required by `handle'. (It specifies if the world, a canvas or nothing has to be redrawn).

Implements VRS::Manipulator.

void VRS::Selector::dragRedraw

InputEvent * VRS::Selector::dragEvent

const [inline]

The drag methods perform ray requests with the corresponding ray request object. If no ray request object is specified or if its "mode" is set to `RayRequestDoNothing', nothing is done. The callbacks are execute in always. Each time a drag method is called, it sets the return code for refreshing the window to `BehaviorRedrawWindow'. To set the return code to a different code, use 'dragRedraw' - this return code will be used instead, but only one time. `dragEvent' returns the event responsible for calling a drag method. It is only availabe during the call of one of the drag methods and callbacks.
