Method Detail

dispose

public void dispose()

Description copied from interface: Disposable

Dispose of the object (unregister listeners, close open resources etc). It should be safe to call this method more than once. Note for beans that support client event listeners: if there are listeners registered when this is called, this method should do nothing.

Specified by:

dispose in interface Disposable

selectionChanged

public void selectionChanged(SelectionEvent e)

SelectionListener interface implementation: does nothing.

Specified by:

selectionChanged in interface SelectionListener
