Constructor Detail

Graph2DViewActions.UngroupSelectionAction

public Graph2DViewActions.UngroupSelectionAction()

Creates a new UngroupSelectionAction that has no default view. Invoking this constructor is equivalent to:

new UngroupSelectionAction(null)

Graph2DViewActions.UngroupSelectionAction

public Graph2DViewActions.UngroupSelectionAction(Graph2DView view)

Creates a new UngroupSelectionAction

Parameters:

view - the default view that is used if the actual view cannot be determined from the information provided by an ActionEvent.

Method Detail

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent e)

ungroupSelection

public void ungroupSelection(Graph2DView view)

Ungroups all node for which acceptNode(Graph2D,y.base.Node) returns true.

Parameters:

view - The view where all information is used from.

acceptNode

protected boolean acceptNode(Graph2D graph,
                             Node node)

Check whether a node should be changed by this action.

This method should return true iff node should be included in the group. This implementation returns true iff the node is currently selected.

Returns:

true iff node should be grouped.

prepareEdges

protected EdgeList prepareEdges(NodeList groupNode,
                                Graph2D g)

Performs necessary actions with all edges that may be touched by this action.

This implementation does nothing.

Returns:

A list of all edges that have been prepared by this method.

convertEdges

protected void convertEdges(EdgeList preparedEdges,
                            Graph2D g)

Performs necessary actions with all edges that may be touched by this action.

This implementation does nothing.

Parameters:

preparedEdges - A list of all edges that have been prepared by a call to prepareEdges(y.base.NodeList,y.view.Graph2D) .
