Ah that works only if the widget is nested in 1 object (eg. direct
parent).
The widget is dynamically added to various objects and can be nested
at different levels.
Currently i am using a VERY dodge way of this.getParent().getParent
().getParent().getParent().doSomething(); :)
And in that doSomething() it would have something like.
doSomething()
{
widget.someOtherwidget.widget1.widget2.widget3.widget4.doStuff();
}
I am sure there is a better way to do this. Gregor's suggestion of an
observer pattern sounds about right.
Although there doesnt seem to be that much information that comes up
around implementing patterns in google when dealing with events in
objects unless you specifically look for it.
I'll have a search and come back here if i still have issues.
