The way you had your code, the Child class will never receive the
killingFocus call. Add a Delegate within the Mother Class to put the
onKillFocus event into scope with Child...
import mx.utils.Delegate;
class Mother extends MovieClip {
public var txt:TextField;
public function Mother() {
//this.onPress = killingFocus;
this.txt.onKillFocus = Delegate.create(this, killingFocus);
}
public function killingFocus():Void {
trace("testFunc in mother");
}
}

Subject: [Flashcoders] Problem extending inherited function
Hi, I have a problem extending an inherited function. I put all the
files described here in a zip if you want to test it yourselves:
http://www.webguidepartner.com/~johan/super-problem.zip
I have this mother-class:
class Mother extends MovieClip {
public var txt:TextField;
public function Mother() {
this.onPress = killingFocus;
//this.txt.onKillFocus = killingFocus;
}
public function killingFocus():Void {
trace("testFunc in mother");
}
}
...and this child-class that inherits from Mother:
class Child extends Mother {
public function Child() {
super();
}
public function killingFocus():Void {
super.killingFocus();
trace("testFunc in child");
}
}
Now, I have a test.fla that contains a movie clip that is linked to
Child. Everything works as expected, both lines of trace running on the
onPress.
But now: comment out the onPress-event in the constructor in Mother, and
uncomment the second line: this.txt.onKillFocus = killingFocus;
Now, there is a text field inside the movie clip. When this text field
loses focus, you wold expect the code to run the same way, but no. The
killingFocus-function in Mother is overwritten and only the trace in
Child runs.
I have some clue that the problem must have something to do with that it
is the text field that triggers the event, and not the movie clip. But
you would expect the super.killingFocus(); to work anyway, regardless of
what calls the function?!
Regards,
/Johan
