@brief 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.
