Re: [Flashcoders] AS3 properties woes
Thanks Steven
In AS3 you can actually put code before a super() as you can in other
methods in AS2.
as i admitted, clearly need a some refactoringright now its just a
prototype so i'm not too concerned

super() must be the first line of code in a constructor.
You should pass the labelClass value to the super constructor (watch
your every move, super constructor).
super(date);
and in your parent
function ClassName(lc:String)
{
labelClass = lc;
}

Thanks guys, its was actually my fault,
the example i gave was a little simpler than my real code,
and i discovered i was calling setTitle from inside the super
construtor, so obviously if i dont set my subclass variable
before calling super() it wont use that variable.
by changing the subclass constructor to this:
public function DateMarker ()
{
labelClass = date
super();
}
I have the desired functionalitythink i probably need to
spend some time refactoring tho.
The example i've given (aside from Petro's astute comment)
should actually work as expected, not as i described!! Sorry
for the distractions!!!

[Flashcoders] AS3 properties woes
Slightly confused
I have a super class:
package com.ktec.timeline
{
protected var labelClass:String = default;
public class AbstractMarker {
public function AbstractMarker ()
{
labelClass = default;
}
public function showTitle (title:String):void
{
trace(span class=\ + labelClass + \ + title + /span)
}
}
}
and a subclass:
package com.ktec.timeline
{
public class DateMarker extends AbstractMarker
{
public function DateMarker ()
{
super();
labelClass = date
}
}
}
Then i use:
var marker:DateMarker = new DateMarker()
marker.showTitle(hello world) # span class=defaulthello world/span
This isnt what i would expect?
Can anyone enlighten me where i'm going wrong?
thanks
keith

Hi Keith,
Little question: what r u working under: Flash 9 Beta or Flex 2? I
wonder your code even compiled. Move this line:
protected var labelClass:String = default;
inside your class definition. It's outside the scope of the class. I
tried it out, worked fine for me.
Cheers,
Petro

RE: [Flashcoders] AS3 properties woes
Not an AS3 expert by any means, but my first thought is that the error is
here:
public class DateMarker extends AbstractMarker
{
public function DateMarker ()
{
super();
labelClass = date
}
}
I'm not sure, but the super() function looks out of place here. You're
already invoking the AbstractMarker constructor by creating a subclass, so
it should work by itself. I suspect that calling super() there has messed
with your scope somehow.
Feel free to shoot me down.

Re: [Flashcoders] AS3 properties woes
Also not an AS3 expert, but I think Danny is wrong. The super function
is necessary to call the parent constructor. I believe that the problem
is related to what Petro said about labelClass being outside of the
AbstractMarker class. I would also consider subclassing showTitle and
adding a trace to see if the value is correct in the DateMarker version.
If so, then someone the two labelClass variables aren't the same actual
variable which would be weird :)

Brandon Barkley Also not an AS3 expert, but I think Danny is wrong. The super function is necessary to call the parent constructor. Hi Brandon, I'm afraid u r wrong. Just try it out, the constructor IS being called once u extend the class.

Re: SPAM-LOW: RE: [Flashcoders] AS3 properties woes
If that's the case, that's a really stupid bit of functionality because you can't completely override a constructor. I was not aware that AS did it that way.

Re: SPAM-LOW: RE: [Flashcoders] AS3 properties woes
Programming ActionScript 3.0 Overview of ActionScript Programming Object-Oriented Programming in ActionScript Classes http://livedocs.macromedia.com/flex/2/docs/1842.html If the superclass constructor is not explicitly called, the compiler automatically inserts a call before the first statement in the constructor body. You can call super() anywhere in your constructor (before or after other code), but if you leave it out, super() is called for you.

This behavior has changed in AS3, you can now call super() at any point in

Re: [Flashcoders] AS3 properties woes
You can put code before super(). If you intend to use any super methods
then you definitely need to call super() beforehand. But if you want to
call a method of your sub class before super(), it does work.
.. now I don't necessarily agree with doing that, but I guess it depends
on what you need to accomplish.
