org.eclipse.gef.editparts
Class ScalableFreeformRootEditPart

                  extended by
org.eclipse.gef.editparts.ScalableFreeformRootEditPart
All Implemented Interfaces:
EditPart, GraphicalEditPart, LayerConstants, LayerManager, RequestConstants, RootEditPart

public class ScalableFreeformRootEditPart
extends FreeformGraphicalRootEditPart

Adds Zoom support to the standard FreeformGraphicalRootEditPart. This root is just like its superclass, except it inserts a new LayeredPane above the printable layers. This pane is identified with the LayerConstants.SCALABLE_LAYERS ID. This root also provides a ZoomManager, for optional use with the ZoomComboContributionItem

The structure of layers (top-to-bottom) for this root is:
Root Freeform Layered Pane
 Guide Layer
 Feedback Layer
 Handle Layer
 Scalable Layers ( ScalableFreeformLayeredPane)
   Scaled Feedback Layer
   Printable Layers
    ├ Connection Layer
    └ Primary Layer  
   Grid Layer

Since:
2.1

Constructor Detail

ScalableFreeformRootEditPart

public ScalableFreeformRootEditPart()
Constructor for ScalableFreeformRootEditPart

Method Detail

createLayers

protected void createLayers(
LayeredPane layeredPane)
Description copied from class: FreeformGraphicalRootEditPart
Creates the top-most set of layers on the given layered pane.

Overrides:
createLayers in class FreeformGraphicalRootEditPart
Parameters:
layeredPane - the parent for the created layers
See Also:
FreeformGraphicalRootEditPart.createLayers(LayeredPane)

createScaledLayers

protected 
ScalableFreeformLayeredPane createScaledLayers()
Creates a layered pane and the layers that should be scaled.

Returns:
a new freeform layered pane containing the scalable layers

getLayer

public 
IFigure getLayer(java.lang.Object key)
Description copied from class: FreeformGraphicalRootEditPart
Returns the layer indicated by the key. Searches all layered panes.

Specified by:
getLayer in interface LayerManager
Overrides:
getLayer in class FreeformGraphicalRootEditPart
See Also:
FreeformGraphicalRootEditPart.getLayer(Object)

getScaledLayers

protected 
LayeredPane getScaledLayers()
Returns the scalable layers of this EditPart

Returns:
LayeredPane

getZoomManager

public 
ZoomManager getZoomManager()
Returns the zoomManager.

Returns:
ZoomManager

register

protected void register()
Description copied from class: AbstractEditPart
Registers itself in the viewer's various registries. If your EditPart has a 1-to-1 relationship with a visual object and a 1-to-1 relationship with a model object, the default implementation should be sufficent.

Overrides:
register in class FreeformGraphicalRootEditPart
See Also:
AbstractEditPart.register()

unregister

protected void unregister()
Description copied from class: AbstractEditPart
Undoes any registration performed by AbstractEditPart.register(). The provided base classes will correctly unregister their visuals.

Overrides:
unregister in class FreeformGraphicalRootEditPart
See Also:
