List of all members.


Detailed Description

GeometryLayer class.

There are two different layer types:

MapLayers also can display Geometry objects. The difference to the GeometryLayer is the repainting. Objects that are added to a MapLayer are "baken" on the map. This means, when you change it´s position for example the changes are not visible until a new offscreen image has been drawn. If you have "static" Geometries which won´t change their position this is fine. But if you want to change the objects position or pen you should use a GeometryLayer. Those are repainted immediately on changes.
