Parameters:

nodeText - the text to set as nodeText

ActionNode

public ActionNode(String nodeText,
                  String nodeType)

Constructs an ActionNode. The nodeText and nodeType properties are initialized with the specified text and type strings.

Parameters:

nodeText - the text to set as nodeText

type - the type to set as nodeType

Method Detail

setActionList

public void setActionList(StaticStringListInterface actionList)

Sets the list of actions that can be performed on the current node.

Parameters:

actionList - string list to set as the actions

public void performAction(Object action)

Directs an object to perform an action.

Specified by:

performAction in interface ActionInterface

Parameters:

action - the action to be performed

Parameters:

listener - the action listener to add

removeActionListener

public void removeActionListener(ActionListener listener)

Removes the specified action listener so it no longer receives action events from this node.

Parameters:

listener - the action listener to remove

processActionEvent

protected void processActionEvent(ActionEvent e)

Processes action events occurring on this node by dispatching them to any registered ActionListener objects. NOTE: This method will not be called unless action events are enabled for this component; this happens when one of the following occurs: a) An ActionListener object is registered via addActionListener() b) Action events are enabled via enableEvents()

Parameters:

e - the action event
