Class MapComponent

java.lang.Object

com.codename1.ui.Component

com.codename1.ui.Container

com.codename1.maps.MapComponent

All Implemented Interfaces:

Animation, Editable, StyleListener, Iterable<Component>

Deprecated.

we highly recommend migrating to the native maps cn1lib

public class MapComponent
extends Container

All communication with the map and layers should be done in WGS84, it takes care of coordinates transformation.
