org.flexdock.docking.defaults.AbstractDockable
All Implemented Interfaces:
EventListener, Dockable, DockingListener, DockingMonitor

public abstract class AbstractDockable extends Object implements Dockable
Provides a default implementation of the Dockable interface. This class should be extended by any application that wishes to make use of the Dockable interface without the need for writing out an implementation for every method that isn't explicitly used.

  • Constructor Details

    • AbstractDockable

      public AbstractDockable(String id)
      Creates a new AbstractDockable instance. This constructor is meant to be invoked by subclasses as it initializes the Dockable's persistent ID and drag sources.
      Parameters:
      id - the persistent ID of the resulting Dockable

    • getClientProperty

      public Object getClientProperty(Object key)
      Returns the value of the property with the specified key. Only properties added with putClientProperty will return a non-null value. If key is null, a null reference is returned.

      If the Component returned by getComponent() is an instance of JComponent, then this method will dispatch to that JComponent's getClientProperty(Object, Object) method. Otherwise, this Dockable will provide its own internal mapping of client properties.

      Specified by:
      getClientProperty in interface Dockable
      Parameters:
      key - the key that is being queried
      Returns:
      the value of this property or null
      See Also:
    • putClientProperty

      public void putClientProperty(Object key, Object value)
      Adds an arbitrary key/value "client property" to this Dockable. null values are allowed. If key is null, then no action is taken.

      If the Component returned by getComponent() is an instance of JComponent, then this method will dispatch to that JComponent's putClientProperty(Object, Object) method. Otherwise, this Dockable will provide its own internal mapping of client properties.

      Specified by:
      putClientProperty in interface Dockable
      Parameters:
      key - the new client property key
      value - the new client property value; if null this method will remove the property

    • getDockingProperties

      public DockablePropertySet getDockingProperties()
      Returns a DockablePropertySet instance associated with this Dockable. This method returns the default implementation supplied by the framework by invoking getDockablePropertySet(Dockable dockable) on org.flexdock.docking.props.PropertyManager and supplying an argument of this.
      Specified by:
      getDockingProperties in interface Dockable
      Returns:
      the DockablePropertySet associated with this Dockable. This method will not return a null reference.
      See Also:
    • getDockingPort

      public DockingPort getDockingPort()
      Returns the DockingPort within which this Dockable is currently docked. If not currently docked, this method will return null.

      This method defers processing to getDockingPort(Dockable dockable), passing an argument of this. This DockingPort returned is based upon the Component returned by this Dockable's abstract getComponent() method.

      Specified by:
      getDockingPort in interface Dockable
      Returns:
      the DockingPort within which this Dockable is currently docked.

    • addPropertyChangeListener

      public void addPropertyChangeListener(PropertyChangeListener listener)
      Description copied from interface: Dockable
      Adds a PropertyChangeListener to the listener list. The listener is registered for all bound properties of this class. Note that if this Dockable is inheriting a bound property, then no event will be fired in response to a change in the inherited property.

      If listener is null, no exception is thrown and no action is performed.

      Specified by:

    • removePropertyChangeListener

      public void removePropertyChangeListener(PropertyChangeListener listener)
      Description copied from interface: Dockable
      Removes a PropertyChangeListener from the listener list. This method should be used to remove PropertyChangeListeners that were registered for all bound properties of this class.

      If listener is null, no exception is thrown and no action is performed.
