Method Detail

addSelectionListener

public void addSelectionListener(ISelectionListener listener)
Adds the given selection listener. Has no effect if an identical listener is already registered.

Parameters:
listener - a selection listener

addSelectionListener

public void addSelectionListener(String partId,
                                 ISelectionListener listener)
Adds a part-specific selection listener which is notified when selection changes in the part with the given id. This is independent of part activation: the part need not be active for notification to be sent. The listener is also notified when the part is created and disposed. When the part is created, the listener is passed the part's initial selection. When the part is disposed, the listener is passed a null selection.

Parameters:
partId - the id of the part to track
listener - a selection listener
