Constructor Detail

Graph2DViewActions.OpenFoldersAction

public Graph2DViewActions.OpenFoldersAction()

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

new OpenFoldersAction(null)

Graph2DViewActions.OpenFoldersAction

public Graph2DViewActions.OpenFoldersAction(Graph2DView view)

Creates a new OpenFoldersAction

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(ActionEvent e)

openFolders

public void openFolders(Graph2DView view)

Opens all folders 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 folderNode)

Check whether a node should be changed by this action. This method should return true iff groupNode should be closed.

Returns:

true iff groupNode should be closed.

openFolder

public void openFolder(Node groupNode,
                       Graph2D graph)

Opens a single folder node. This method opens the folder unconditionally. In addition, if Graph2DViewActions.AbstractGroupingAction.getNodeStateChangeHandler() is not null, it is used to configure the relevant edges after opening the node.

configureGroupRealizer

protected void configureGroupRealizer(NodeRealizer nr)

Updates the folder/group state of the specified realizer if necessary.
