DVEventInterface Class Reference

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