DVEventInterface Class Reference

The DVEventInterface class This class is the main interface for manage event of a Diagram View. This do nothing, for create new event behavior, we must to create new class from this. Each method return a bool: True if the methode do something else return false. Each method of DVEventInterface return false; isRunning() return true if action is started but not finish. By default return false. isFinish() return true when the action is finish, or not started. By default return true. More...
