/**
* @brief The DiagramEventInterface class
* 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 running (do something). By default return false.
*
* ##USE DiagramEventInterface##
* This class is the basic interface for manage event on a diagram.
* To create a behavior for event diagram, we need to herite this class.
* This interface work like this :
* You need to create an interface and call diagram::setEventInterface(*your_interface).
* You need to create an interface and call diagram::setEventInterface(pointer_of_your_interface).
* When a diagram get an event (mouse or key) if they have an event interface,
* they send the event to the interface (for exemple mousePressEvent).
* If the interface do something with this event, you need to return true to signal the diagram you work with this event.
* (if you do nothing by defaut the interface return false, so diagram do nothing)
* they send the event (with the status accepted to false) to the interface (for exemple mousePressEvent).
* If the interface do something with this event, you need to set to true the accepted status of the event, then diagram do nothing.
* When the interface job is done, we need to emit the signal finish(), the diagram use this signal to delete the interface.
* Be carreful with the destructor, diagram can at any time (even if interface is still running) delete the interface,
* the bool m_abort is here for that at destruction time.
