Constructor & Destructor Documentation

IlvMakeZoomInteractor::IlvMakeZoomInteractor	(	IlvManager *	manager,
		IlvView *	view
	)

Constructor.

Initializes a new instance of the IlvMakeZoomInteractor class.

Parameters

manager	The manager.
view	The manager view.

Member Function Documentation

virtual void IlvMakeZoomInteractor::doIt ( IlvRect &  rect )

virtual

Action performed to finalize the interaction.

Modifies the IlvTransformer associated with the view. The new transformer is computed in such a way that, when applied to rect, the result is the client area of the view.

Parameters

rect	The rectangle used to compute the new transformer.

Reimplemented from IlvDragRectangleInteractor.

void IlvMakeZoomInteractor::useDefaultTransitionScheduler	(	IlBoolean	value = IlTrue,
		IlUInt	duration = 1000
	)

Tells the interactor whether to use the default transition scheduler to zoom the view.

Parameters

value	A Boolean value specifying whether to use or not the default transition scheduler to unzoom the view. If value is IlFalse, no transition scheduler will be used.
duration	The duration that the transition will take to complete. The value is a number of milliseconds.
