/**
* Controller of the rootmap panel.
*
* The RootMapPanelController is the
* MapController
implementation for the JXMap geoviewer
* implementation. It exposes methods to control this map implementation.
*
* Swing hierarchy
The top swing component for the
* RootMapController
is the
* {@link MapViewerTopComponent}. This TopComponent only contains the hook to
* the netbeans window management system, like {@link #setActive(boolean)} on
* componentActivated and componentDeactivated. The controller delivers the root
* panel to TopComponent which is a {@link RootMapPanel}. The Controller
* controls the state and content of this root panel.
The {@link RootMapPanel}
* is a
* JXPanel
which contains a JLayerPane. The layered pane contains
* several layers starting with the JXMap layer as background.
Layer
* containing object ({@link ObjectLayer)} implementations) are represented as
* an {@link ObjectLayerPanel} and added to the layered panel on the {@link RootMapPanel.LayerGroup#LAYER_ACTIVE}
* position.
* ObjectLayerPanel
s are ObjectScenes and contain
* LayerObjectWidget
s representing geographical components on the
* map.
