Superclass constructor call missing in Event Handler examples?

[ehrenfeu]

The wiki examples on how to create an event handler does not call the superclass constructor - is this just missing or is it done on purpose?

In the latter case, I think it should be explained why the constructor is not called.

Hello,

I think this is explained here but of course feel free to edit the wiki page if you want to improve it.
