Interface CVetoClosingListener

public interface CVetoClosingListener

This listener can be called before a CDockable or a set of CDockables are closed. Subclasses can fire a veto indicating that some CDockable must not yet be closed.
Please note:

• It may not always be possible to cancel a closing-operation.
• There is no guarantee that closing(CVetoClosingEvent) is called before closed(CVetoClosingEvent)
• The event-object passed to closing(CVetoClosingEvent) and closed(CVetoClosingEvent) may not be equal, even if they describe the same event
• Events may be split: if closing(CVetoClosingEvent) was called once and handled three dockables, then closed(CVetoClosingEvent) may be called three times to handle one dockable
• MultipleCDockables that are not children of a CWorkingArea are closed and re-opened if the layout changes (CControl.load(String)). This may be prevented with a correct implementation of MultipleCDockableFactory.match.
