Constructor Detail

ScreenDockStationFactory

public ScreenDockStationFactory(Window owner)

Constructs a factory

Parameters:

owner - the window which will be used as owner for dialogs

ScreenDockStationFactory

public ScreenDockStationFactory(WindowProvider owner)

Constructs a factory

Parameters:

owner - the window which will be used as owner for dialogs

Method Detail

getProvider

public WindowProvider getProvider()

Gets the provider for windows, which will be used as owner for newly created dialogs.

Returns:

the owner

getID

public String getID()

Description copied from interface: DockConverter

Gets the unique name of this converter. Please note that unique identifiers starting with "dock." should not be used by clients.

Specified by:

getID in interface DockConverter<ScreenDockStation,ScreenDockPerspective,ScreenDockStationLayout>

Returns:

the id

estimateLocations

public void estimateLocations(ScreenDockStationLayout layout,
                              LocationEstimationMap children)

Description copied from interface: DockFactory

Tries to estimate the DockablePropertys of the children of the station which is represented by layout.
The children of this station are accessible through children.getChild( ... ), this factory may also access the leafs in the tree of Dockables through children.getSubChild(...).
Note: this method must not set the successor of any DockableProperty, it is the callers responsibility to handle chains of stations.

Specified by:

estimateLocations in interface DockFactory<ScreenDockStation,ScreenDockPerspective,ScreenDockStationLayout>

Parameters:

layout - this station

children - the children of the station, this method should call DockLayoutInfo.setLocation(DockableProperty) or LocationEstimationMap.setLocation(int, DockableProperty) and LocationEstimationMap.setLocation(int, int, DockableProperty) for as many children as possible

getLayout

public ScreenDockStationLayout getLayout(ScreenDockStation station,
                                         Map<Dockable,Integer> children)

Description copied from interface: DockConverter

Gets the layout of element. This method should create a new instance of the layout object, that new object should not be tied to element in any way. A layout can be living for a long period of time and might be used on another dockable object.

Specified by:

getLayout in interface DockConverter<ScreenDockStation,ScreenDockPerspective,ScreenDockStationLayout>

Parameters:

station - the element for which a new layout should be created

children - a map containing unique identifiers for the children of the element. Children which are not in this map should not be stored in the layout.
The identifiers are in the range from 0 (incl.) to children.size() (excl.). The same identifiers will be used as indices by a LocationEstimationMap. See also DockFactory.estimateLocations(Object, LocationEstimationMap).

Returns:

the newly created, independent layout object.
