@brief The DiagramEventInterface class

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(pointer_of_your_interface).
|
|
When a diagram get an event (mouse or key) if they have an event interface,
|
|
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.
