Detailed Description

Interactor to add toggle behavior to graphic objects.

Library: views

Use this class to give an object the behavior of a toggle button. The object with which this interactor is associated is inverted when the user presses and then releases the mouse button over it. This is done by calling the object member function IlvGraphic::invert().

The registered name of this interactor is "Toggle".
