Detailed Description

Manager interactor class.

Library: ilvmgr

Use this class to create an IlvOutlinePolygon object in a view controlled by a manager. The virtual member function handleEvent monitors mouse events. To draw an outline polygon, the user:

1. Clicks the left mouse button to set the point.

2. Presses the space bar, the enter key or double-clicks to finish.
