GenericNodeRealizer.GenericMouseInputEditorProvider, MouseInputEditor

public class MultiplexingNodeEditor
extends AbstractMouseInputEditor
implements GenericNodeRealizer.GenericMouseInputEditorProvider

MouseInputEditor that multiplexes between one or more subordinate editors. Each subordinate editor may take responsibility for handling an editing gesture according to event position and type.

Nested Class Summary

static class	MultiplexingNodeEditor.EventReporter Editor that plays recorded MouseEvents back to a parent EditMode instance for further processing.
static interface	MultiplexingNodeEditor.NodeEditor A class implementing this interface can be added to a MultiplexingNodeEditor and implements one behaviour of a node triggered by a mouse gesture.

Constructor Summary

MultiplexingNodeEditor()
Creates a new MultiplexingNodeEditor without any subordinate editors.

Method Summary

void	addNodeEditor(MultiplexingNodeEditor.NodeEditor editor) Adds the specified editor as a subordinate editor to the MultiplexingNodeEditor instance.
MouseInputEditor	findMouseInputEditor(NodeRealizer context, Graph2DView view, double x, double y, HitInfo hitInfo) Used as a callback for the GenericNodeRealizer.findMouseInputEditor(Graph2DView, double, double, HitInfo) method.
java.util.Collection	getNodeEditors() Returns a read-only view of the MultiplexingNodeEditor's subordinate editors.
void	mouse2DEventHappened(Mouse2DEvent event) Listener-like interface that will be notified of Mouse2DEvents.
void	removeNodeEditor(MultiplexingNodeEditor.NodeEditor editor) Removes the specified editor from the MultiplexingNodeEditor's collection of subordinate editors.
boolean	startsEditing(Mouse2DEvent event) This method is used by clients to query whether the given event is deemed as a starting gesture.
