Method Detail

handleEvent

public boolean handleEvent(VisualElementEvent event)

Description copied from interface: VisualElement

Handler method that is called for handling events. Events can be cursor events, selection events etc.

Specified by:

handleEvent in interface VisualElement

Overrides:

handleEvent in class NodeFigure

Parameters:

event - Event that desribes the event

Returns:

true: The event was handled by the element.
false: No special handling, perform the default handling.

updateFigure

public void updateFigure()

Description copied from class: NodeFigure

In addition to synchronization all children, synchronizes the presentation figure if applicable.

Specified by:

updateFigure in interface UpdatableFigure

Overrides:

updateFigure in class NodeFigure

getDropRegionIdForFlavor

protected java.lang.String getDropRegionIdForFlavor(java.util.List flavors,
                                                    java.awt.datatransfer.Transferable data,
                                                    java.awt.event.MouseEvent mouseEvent)

Determines if none of the flavors in the list is accepted by DnD actions.

Overrides:

getDropRegionIdForFlavor in class MultiSocketNodeFigure

Parameters:

flavors - Flavors to check

data - Transferred object

mouseEvent - Mouse event of the DnD drop action

Returns:

The region id that should be used for the accepted flavor or null if the flavor is not accepted

importData

public boolean importData(java.lang.Object regionId,
                          java.awt.datatransfer.Transferable data,
                          java.awt.Point p)

Description copied from interface: InteractionClient

Imports the given transferable into the given region.

Specified by:

importData in interface InteractionClient

Overrides:

importData in class MultiSocketNodeFigure

Parameters:

regionId - Id of the region to import into (see BasicDropRegion.getId)

data - Transferable to import

p - Drop point in glass coordinates

Returns:

true The data was successfully imported.
false An error occured while importing the data.

Parameters:

mo - Model object to reference

assignPlaceholderReference

public void assignPlaceholderReference(java.lang.String referencePath)
