Interface DCTransactionStateListener

All Known Subinterfaces:

JUTransactionStateListener

All Known Implementing Classes:

JUNavigationBar, JUStatusBar

public interface DCTransactionStateListener

Implemented by controls/classes that need to react to a change in a transaction's state. Typically, controls like status bar and navigation bar need to update their display with a dirty flag/button that indicates whether the ensuing transaction is clean or not. Those classes can implement this interface and add themselves to the DCApplication's transaction state listener's list so that they get notified of the change.
