Constructor Detail

CommonDockableFactory

public CommonDockableFactory(String id,
                             MultipleCDockableFactory<?,?> delegate,
                             CControlAccess access)
Creates a new factory.

Parameters:
id - the identifier of this factory
delegate - the factory that should be used to load the contents of the new CommonDockable
access - access to the internal affairs of a CControl
Method Detail

getID

public String getID()
Description copied from interface: DockFactory
Gets the unique name of this factory.

Specified by:
getID in interface DockFactory<CommonDockable,CommonDockableLayout>
Returns:
the id

getLayout

public CommonDockableLayout getLayout(CommonDockable element,
                                      Map<Dockable,Integer> children)
Description copied from interface: DockFactory
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 DockFactory<CommonDockable,CommonDockableLayout>
Parameters:
element - 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.
Returns:
the newly created, independent layout object.

layout

public CommonDockable layout(CommonDockableLayout layout,
                             Map<Integer,Dockable> children)
Description copied from interface: DockFactory
Creates a new DockElement and changes the layout of the new element such that is matches layout.

Specified by:
layout in interface DockFactory<CommonDockable,CommonDockableLayout>
Parameters:
layout - the new layout
children - some children, note that the map may not contain all elements which were present when the layout was created.
Returns:
a new element or null if layout can't be used

layout

public CommonDockable layout(CommonDockableLayout layout)
Description copied from interface: DockFactory
Creates a new DockElement and changes the layout of the new element such that is matches layout. This method should not add any children to the element.

Specified by:

Parameters:
layout - the new layout
Returns:
a new element or null if layout can't be used

setLayout

public void setLayout(CommonDockable element,
                      CommonDockableLayout layout,
