Interface VetoableDockFrontendListener

All Known Implementing Classes:

VetoableDockFrontendAdapter

public interface VetoableDockFrontendListener

This listener is added to a DockFrontend. It gets informed before and after a Dockable is shown or hidden. In some cases this listener can cancel the operation.
The number of calls of a method of this listener does not have to be the same number for any other method. Also an array of Dockables given to one method may be split up into many arrays the next time or when given to another method. It is however guaranteed that there are no false alarms (i.e. an already invisible Dockable will never be given to hiding(VetoableDockFrontendEvent)).
Note: the scope of this listener is limited, please read the comments of DockFrontend.addVetoableListener(VetoableDockFrontendListener) for further information.

hiding

void hiding(VetoableDockFrontendEvent event)

Called before a set of Dockables is hidden. To abort the operation, VetoableDockFrontendEvent.cancel() can be invoked.
