Detailed Description

Manager interactor class.

Library: ilvmgr

Use this class to create IlvArrowLine objects in a view controlled by a manager. The virtual member function handleEvent monitors mouse events. To draw a line, the user:

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

  2. Drags the other end of the line by moving the mouse with the button held down.

  3. Releases the mouse button to indicate the end point.

The method drawGhost displays the intermediate states of the line being defined.
