function anyMethod(obj)
...
notify(obj,'EventName');
end
end
end
Any function or method can trigger the event for a specific instance of the class defining
the event. For example, the triggerEvent method calls notify to trigger the
StateChange event:
classdef MyClass < handle
events
StateChange
end
methods
function triggerEvent(obj)
notify(obj,'StateChange')
end
end
end
Trigger the StateChange event with the triggerEvent method:
obj = MyClass;
obj.triggerEvent
Create Listener
Define a listener using the handle class handle.addlisteneror handle.listener
method. Pass a function handle for the listener callback function using one of these
syntaxes:
- addlistener(SourceOfEvent,'EventName',@functionName) — for an ordinary
function. - addlistener(SourceOfEvent,'EventName',@Obj.methodName) — for a method
of Obj. - addlistener(SourceOfEvent,'EventName',@ClassName.methodName) — for a
static method of the class ClassName.
ListenerObject = addlistener(SourceOfEvent,'EventName',@listenerCallback);
addlistener returns the listener object. The input arguments are:
