Class PanelGroupManager

java.lang.Object

org.gvsig.gui.beans.panelGroup.PanelGroupManager

All Implemented Interfaces:

Serializable

public class PanelGroupManager
extends Object
implements Serializable

Implemented to use the AbstractPanelGroup type desired.

This class allows having different implementations of AbstractPanelGroup and only load in memory the class of some of them, whom have previously been imported to future use. Then, when a graphical interface would need use a AbstractPanelGroup instance, will instance an object of the class selected (set previously as default) of the registered types in this manager.
