onunload method

[thomas]

There are many times when the existence of the above method for some
widgets, especially boxes, would have saved me from a lot of coding.

How feasible is the implementation of such a method?

Thanks

This should be a base widget method. I think this should be
implemented by adding a specific custom event handler that gets fired
just before destroying each widget (thus we're gonna have an
"onunload" custom event). I think it would be fairly easy to
implement.

So here is an implementation of the onunload event:

Widget.prototype.destroy = function(w) {
var w = w || this;
if(w._customRegistry['onunload'])
w._customRegistry['onunload'](w);
QuiX.removeWidget(w);
}

And

Widget.prototype.customEvents = ['onload','onresize','ondrop','onunload'];

Thanks Thomas. This seems valid enough. I merged this in the Porcupine
trunk. So it seems that our widgets have a new custom event :).
