Detailed Description

Manager interactor class.

Library: ilvmgr

Use this class to create arc objects in a view controlled by a manager. To create an arc, the user:

1. Creates a rectangle area bounding the entire arc to be created.

2. Specifies the starting and ending angle of the arc by manipulating two square handles.

To create IlvArc objects, use the IlvMakeArcInteractor interactor.
