public class View
extends JComponent
implements Dockable, DockingConstants

The View class is slightly incompatible with JComponent. Similar to JFC/Swing top-level containers, a View contains only a content pane Container and a Titlebar. The content pane should contain all the components displayed by the View. As a convenience add and its variants, remove(Component) and setLayout have been overridden to forward to the contentPane as necessary. This means you can write:

 view.add(child);
 
And the child will be added to the contentPane. The content pane will always be non-null. Attempting to set it to null will cause the View to throw an exception. The default content pane will not have a layout manager set.

getDockingProperties

public DockablePropertySet getDockingProperties()
Description copied from interface: Dockable
Returns a DockablePropertySet instance associated with this Dockable. Developers implementing the Dockable interface may or may not choose to provide their own DockablePropertySet implementation for use with this method. A default implementation is supplied by the framework and most Dockable implementations, including all implementations provided by the framework, will return the default DockablePropertySet via a call to org.flexdock.docking.props.PropertyManager. Developers are encouraged to take advantage of this by calling PropertyManager.getDockablePropertySet(this).

Specified by:
getDockingProperties in interface Dockable
Returns:
the DockablePropertySet associated with this Dockable This method may not return a null reference.

Overrides:

remove

public void remove(Component comp)
Overrides:

getActionButton

public AbstractButton getActionButton(String actionName)

getComponent

public Component getComponent()
Description copied from interface: Dockable
Returns the Component that is to be dragged and docked. This may or may not be included in the list returned by getDragSources().

The framework performs indexing on the underlying Component. Consequently, this method may not return a null reference.

Specified by:
getComponent in interface Dockable
Returns:
the component wrapped by this dockable.

getDragSources

public List getDragSources()
Description copied from interface: Dockable
Returns a List of the Components that are event sources for drag operations. The list may or may not include the Component returned by getComponent().

Specified by:
getDragSources in interface Dockable
Returns:
a list containing the components that may be used to drag this dockable.

getFrameDragSources

public Set getFrameDragSources()
Description copied from interface: Dockable
Returns a Set of the Components that are used as frame drag sources. When a Dockable is floated into an external frame, that frame may or may not have a titlebar for repositioning. The Components returned by this method will be setup with appropriate event listeners such that dragging them will serve to reposition the containing frame as if they were the frame titlebar. If a Component exists in both the Set returned by this method and the List returned by getDragSources(), the "frame reposition" behavior will supercede any "drag-to-dock" behavior while the Dockable is in a floating state.

Specified by:
getFrameDragSources in interface Dockable
Returns:
a set containing the components that may be used to drag the frame this dockable resides in, if the dockable is floating.

getPersistentId

public String getPersistentId()
Description copied from interface: Dockable
Returns a String identifier that is unique within a JVM instance, but persistent across JVM instances. This is used for configuration mangement, allowing the JVM to recognize a Dockable instance within an application instance, persist the ID, and recall it in later application instances. The ID should be unique within an appliation instance so that there are no collisions with other Dockable instances, but it should also be consistent from JVM to JVM so that the association between a Dockable instance and its ID can be remembered from session to session.

The framework performs indexing on the persistent ID. Consequently, this method may not return a null reference.

Specified by:
getPersistentId in interface Dockable
Returns:
the persistence id for this dockable. This id ensures that only one copy of a given dockable will exist.

isTerritoryBlocked

public boolean isTerritoryBlocked(Dockable dockable,
                                  String region)

setTerritoryBlocked

public void setTerritoryBlocked(String region,
                                boolean blocked)

getTabText

public String getTabText()

setTabText

public void setTabText(String tabText)

getTabIcon

public Icon getTabIcon()

setTabIcon

public void setTabIcon(Icon icon)

dock

public boolean dock(Dockable dockable)
Description copied from interface: Dockable
Implements the semantics for docking an external Dockable to this Dockable and returns a boolean indicating whether or not the docking operation was successful.

The framework already provides a default implementation for this method through DockingManager.dock(Dockable dockable, Dockable parent). While users are free to provide their own implementation for this method, the recommended approach is to use the default implementation with the following line:

return DockingManager.dock(dockable, this);

Specified by:
dock in interface Dockable
Parameters:
dockable - the Dockable to dock relative to this Dockable
Returns:
true if the docking operation was successful; false otherwise.
See Also:
Dockable.dock(Dockable, String), Dockable.dock(Dockable, String, float), DockingManager.dock(Dockable, Dockable)

getDockingPort

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

Specified by:
getDockingPort in interface Dockable
Returns:
the docking port this dockable resides in, or null if the dockable is not currently docked (i.e. in the middle of a drag operation).

getSibling

public Dockable getSibling(String region)

getViewport

public Viewport getViewport()

dock

public boolean dock(Dockable dockable,
                    String relativeRegion)
Description copied from interface: Dockable
Implements the semantics for docking an external Dockable to the specified region of this Dockable and returns a boolean indicating whether or not the docking operation was successful. If the docking operation results in a split layout, this method should determine an appropriate ratio of available space to allot to the new sibling Dockable.

The framework already provides a default implementation for this method through DockingManager.dock(Dockable dockable, Dockable parent, String region). While users are free to provide their own implementation for this method, the recommended approach is to use the default implementation with the following line:

return DockingManager.dock(dockable, this, relativeRegion);

Specified by:
dock in interface Dockable
Parameters:
dockable - the Dockable to dock relative to this Dockable
relativeRegion - the docking region into which to dock the specified Dockable
Returns:
true if the docking operation was successful; false otherwise.
See Also:
Dockable.dock(Dockable, String, float), DockingManager.dock(Dockable, Dockable, String)

dock

public boolean dock(Dockable dockable,
                    String relativeRegion,
                    float ratio)
Description copied from interface: Dockable
Implements the semantics for docking an external Dockable to the specified region of this Dockable with the specified layout ratio, returning a boolean indicating whether or not the docking operation was successful. If the docking operation results in a split layout, this method should use the specified ratio to determine the amount of available space to allot to the new sibling Dockable.

The framework already provides a default implementation for this method through DockingManager.dock(Dockable dockable, Dockable parent, String region, float proportion). While users are free to provide their own implementation for this method, the recommended approach is to use the default implementation with the following line:

return DockingManager.dock(dockable, this, relativeRegion, ratio);

Specified by:
dock in interface Dockable
Parameters:
dockable - the Dockable to dock relative to this Dockable
relativeRegion - the docking region into which to dock the specified Dockable
ratio - the proportion of available space in the resulting layout to allot to the new sibling Dockable.
Returns:
true if the docking operation was successful; false otherwise.
