Properties Methods
Implements MatrixSelectionListener, EventListener
A component that dispatches matrix-selection events to multiple listeners. MatrixSelectionMulticaster
maintains an array of listeners. The add()
, remove()
, and find()
methods maintain this list.
The hasListeners()
method determines whether any objects are listening for matrix-selection events. The dispatch()
method sends a matrix-selection event to all listeners.
public final synchronized void add(MatrixSelectionListener listener)Adds an object to the array of listeners.
Parameters:
listener
public final void dispatch(MatrixSelectionEvent e)Sends a matrix-model event to all listeners. It is a high-speed dispatcher that does not need to be synchronized. If the event ID is ITEM_CHANGE, it calls the
selectionItemChanged
method of the matrix-selection listeners. If the event ID is RANGE_CHANGE, it calls the selectionRangeChanged
method of the matrix-selection listeners. If the event ID is SELECTION_CHANGE, it calls the selectionChanged
method of the matrix-selection listeners.
Parameters:
e
public int find(MatrixSelectionListener listener)Searches for the specified listener among the array of listening objects.
Parameters:
listener
public final boolean hasListeners()Determines if there are any listeners for matrix-selection events. If the method returns true, one or more listeners are present.
public final synchronized void remove(MatrixSelectionListener listener)Removes the specified listening object from the array of listeners for matrix-selection events.
Parameters:
listener
