Detailed Description

Manager interactor class.

Library: ilvmgr

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

  1. Clicks and drag the left mouse button to add a point and set its tangents and tension.
  2. Presses the return or space key, or double clicks to finish.

If the user presses the Control modifier while dragging the left mouse button, the left and right tangents at the current point are dissociated, letting the user create cusps on the Bezier spline.
