public class SplitDockStation
extends OverpaintablePanel
implements Dockable, DockStation

This station shows all its children at once. The children are separated by small gaps which can be moved by the user. It is possible to set one child to fullscreen, this child will be shown above all other children. The user can double click on the title of a child to change its fullscreen-mode.
The station tries to register a DockTitleFactory with the ID TITLE_ID.

Stations should not change this property directly, they should call DockController.setFocusedDockable(Dockable, boolean) which will then call DockStation.setFrontDockable(Dockable).

                           Dockable dockable)

Description copied from interface: DockStation

Prepares this station to get the new child dockable. The station has to store a possible location of the child, and should draw some indicators where the child will be put. The station can refuse dockable, in this case nothing has to be painted and this method returns false.
There are some constraints:

• The result should be false if this station is dockable, checkOverrideZone is true and the mouse is in the override-zone. of the parent. However, that condition is just "good manners" and may be broken.
• This method should use DockStation.accept(Dockable) and Dockable.accept(DockStation) or Dockable.accept(DockStation, Dockable) to ensure that the desired drop-location is valid.
• The method should use the DockAcceptance of its controller (see DockController.getAcceptance()) to ensure that the drop/location is valid.

This method gets two points: mouseX/mouseY is the location of the mouse, titleX/titleY is the location of the dragged title. The second point may be interesting if the title of a dropped child should have the same coordinates as the image of the dragged title.
This method is never called if dockable is a child of this station. In such a case prepareMove is invoked.

Specified by:

prepareDrop in interface DockStation

Parameters:

x - the x-coordinate of the mouse on the screen

y - the y-coordinate of the mouse on the screen

Returns:

true if dockable can be added at the current location, false otherwise.

draw in interface DockStation

forget

public void forget()

Description copied from interface: DockStation

Tells this station that a possible drop or move on this station was canceled. The station can throw away any information gathered by the last call prepareDrop or prepareMove
If the station is drawing some markings because of a call to DockStation.draw(), than the station can throw away these markings too.

isInOverrideZone

public <D extends Dockable & DockStation> boolean isInOverrideZone(int x,
                                                                  int y,

                                                                  Dockable drop)

Description copied from interface: DockStation

If the controller asks a station if a child could be dropped or moved, the controller assumes that no other station has interest in this event. However if this station is a dockable, and has a parent, the parent might be interested in the new child. This dockable station has to ask the parent if the current location of the mouse is in the override-zone. This station should not accept a child if the parent returns true.
On the other hand, this station could be asked by a child whether the mouse is in the override-zone. If the mouse hits a point of special interest, then the method should return true.
Note: if this station is asked and is a dockable station itself, then this method should ask the parent for his override-zone too.

Specified by:

isInOverrideZone in interface DockStation

Type Parameters:

D - the type of invoker

Parameters:

x - the x-coordinate of the mouse on the screen

y - the y-coordinate of the mouse on the screen

invoker - a child of this station which invoked the method

drop - a Dockable which might become a child

Returns:

true if the location of the mouse is of special interest

canDrag

public boolean canDrag(Dockable dockable)

Description copied from interface: DockStation

Tells whether dockable can be removed from this station or not. This method assumes that dockable is a child of this station, if not, then the behavior of this method is unspecified.
Note that the result of this method may not be respected every time, it's more a hint for the controller how to act.

Specified by:

canDrag in interface DockStation

Parameters:

dockable - a child of this station

Returns:

true if dockable can be dragged

drag

public void drag(Dockable dockable)

Description copied from interface: DockStation

Removes a child from this station. This method may be called even if DockStation.canDrag(Dockable) returned false.
Note: clients may need to invoke DockController.freezeLayout() and DockController.meltLayout() to ensure noone else adds or removes Dockables.

Specified by:

drag in interface DockStation

Parameters:

dockable - the child to remove

fireFullScreenChanged

protected void fireFullScreenChanged(Dockable oldDockable,
                                     Dockable newDockable)

Sends a message to all registered instances of SplitDockListener, that the Dockable in fullscreen-mode has changed.

Parameters:

oldDockable - the old fullscreen-Dockable, can be null

newDockable - the new fullscreen-Dockable, can be null

fireTitleExchanged

protected void fireTitleExchanged(DockTitle title)

Informs all DockableListeners that title is no longer considered to be a good title and should be exchanged.

Parameters:

title - a title, can be null

fireTitleExchanged

protected void fireTitleExchanged()

Informs all DockableListeners that all bound titles and the null title are no longer considered good titles and should be replaced

getStationBounds

public Rectangle getStationBounds()

Description copied from interface: DockStation

Gets a rectangle in which all points of the station are. The user is only able to move a Dockable into this area onto this station.

Specified by:

getStationBounds in interface DockStation

Returns:

the bounds, relative to the screen, null to indicate that this station has not any bounds

canCompare

public boolean canCompare(DockStation station)

Description copied from interface: DockStation

Tells whether this station knows a rule how to compare itself with station. See DockStation.compare(DockStation) for more details.

Specified by:

canCompare in interface DockStation

Parameters:

station - another station

Returns:

true if a call to compare will not end in an exception and return another value than 0

compare

public int compare(DockStation station)

Description copied from interface: DockStation

Compares this station with station. The comparison is needed if the stations bounds of the two station have common points. On a drag-event, the controller needs a way to decide which station is more important (and receives the opportunity to get a new child first). The controller will use the method compare to do this. This method works like Comparable.compareTo(Object).

Specified by:

compare in interface DockStation

Parameters:

station - another station

Returns:

a number less/equal/higher than zero, if this station has higher/equal/lesser priority than station.

asDockable

• The tree should never be invalid. That means that each Node should have two children, and each Leaf should have a Dockable.

Returns:

the root
