Package docking

Class DockingWindowManager

java.lang.Object
docking.DockingWindowManager
All Implemented Interfaces:
PlaceholderInstaller, PropertyChangeListener, EventListener
public class DockingWindowManager extends Object implements PropertyChangeListener, PlaceholderInstaller
Manages the "Docking" arrangement of a set of components and actions. The components can be "docked" together or exist in their own window. Actions can be associated with components so they "move" with the component as it moved from one location to another.

Components are added via ComponentProviders. A ComponentProvider is an interface for getting a component and its related information. The docking window manager will get the component from the provider as needed. It is up to the provider if it wants to reuse the component or recreate a new one when the component is requested. When the user hides a component (by using the x button on the component header), the docking window manager removes all knowledge of the component and will request it again from the provider if the component is again shown. The provider is also notified whenever a component is hidden and shown.
