Remarks

IElement is the generic interface implemented by all Element objects (TextElement, PolygonElement, LineElement, MapSurroundFrame, etc). The interface provides access to the geometry of the element and contains methods for drawing and performing hit tests.

An IElement object gnerally obtained and manipulated by IGraphicsContainer and IGraphicsContainerSelect objects. IElement is most often used when the developer wants to manipulate the selected set of graphics.

The geometry type of objects implementing IElement varies widely depending on what the element does. The remarks of each object implementing IElement will list the geometry types that are valid for that specific element.
