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(java.awt.event.ActionEvent e)

openFolders

public void openFolders(Graph2DView view)

Opens all folders for which acceptNode(Graph2D,y.base.Node) returns true. The default implementation backs up the realizers of all opened folders.

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 folderNode,
                       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.

Note: Client code that calls this method directly (instead of the action's openFolders(Graph2DView) method) should back up the realizer of the specified folder node to ensure that opening the folder can be properly undone.

Parameters:

folderNode - the folder node to be opened.

graph - the graph to which the specified folder node belongs.

configureGroupRealizer

protected void configureGroupRealizer(NodeRealizer nr)

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

isKeepingSelectionState

public boolean isKeepingSelectionState()

Determines whether or not the selection state of a ProxyShapeNodeRealizer instance should be retained when the proxy's delegate realizer is exchanged due to a node state change.

If this property is false, a node state change event might result in an implicit selection state change for ProxyShapeNodeRealizer instances if the selection states of the delegate realizer that is used before the node state change differs from the selection state of the delegate realizer that is used after the node state change.

Defaults to false.

Returns:

true if the selection state of a ProxyShapeNodeRealizer instance is explicitly set again after exchanging its delegate realizer; false otherwise.

See Also:

setKeepingSelectionState(boolean)

setKeepingSelectionState

public void setKeepingSelectionState(boolean enabled)

Specifies whether or not the selection state of a ProxyShapeNodeRealizer instance should be retained when the proxy's delegate realizer is exchanged due to a node state change.

If this property is false, a node state change event might result in an implicit selection state change for ProxyShapeNodeRealizer instances if the selection states of the delegate realizer that is used before the node state change differs from the selection state of the delegate realizer that is used after the node state change.

Defaults to false.

Parameters:

enabled - if true, the selection state of a ProxyShapeNodeRealizer instance is explicitly set again after exchanging its delegate realizer; if false, the selection state of a ProxyShapeNodeRealizer is not explicitly (re-)set.
