McGraphObj Object
    
 
Description

The base interface for all the graphic objects.

Object Model



Remarks

This interface contains all the methods and properties common to all graphic objects maintained by the overlay manager McGraphOverlay. Objects implementing any of the derived interfaces listed below, implement McGraphObj as well, which makes it possible to interact with them in a uniform manner. Most of these objects can be filled or empty.

Each one of the interfaces derived from McGraphObj uses points to define the graphic object shape, and handles to allow its interactive editing. The position and numbering of these points is described in the section devoted to each derived interface below.
