Detailed Description

Manager interactor class.

Library: ilvmgr

Use this class to create IlvArrowPolyline objects in a view controlled by a manager. The virtual member function handleEvent monitors mouse events. To draw a polyline, 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.
