Hi,
The documentation tells :
onBeforeEventChanged
void onBeforeEventChanged(object ev, event e, flag, object ev_old){ … };
It is very convenient to be able to compare modified event (ev) and old one (ev_old).
But the “ev_old” object seems to be never set (seems to be never passed as param in the function when the event is triggered).
Taking a look at above line seems to confirm this.
@see in scheduler._on_mouse_up=function(e){}
in line : if (!this.callEvent("onBeforeEventChanged",[ev, e, is_new])){
// no ev_old as 4rd param ?Regards.
