So with your method I can do this:
Function.prototype.setScopeTo = function(object) {
var __method = this;
return function() {
__method.apply(object, arguments);
}
}
class x {
function setFocusHandler() {
var func = function() {
trace("this="+this) // scope is class x
}
label.onKillFocus = func;
label.onKillFocus.setScopeTo(this);
}
}
