[Mono-list] Howto: Build custom events

[Michał Ziemski]

Hi!

Basically you declare:

class Foo
{
    public delegate void SimpleDelegate();
    public event SimpleDelegate TerribleEvent;
    protected void OnTerribleEvent()
    {
      if (TerribleEvent != null)
        TerribleEvent();
    }
}

and you use OnTerribleEvent to fire the event;

You connect to the event from another class by:
FooInstance.TerribleEvent += MyMethodMatchingSimpleDelegateSignature();

Cheers!
