Re: [flexcoders] Re: Accepting MXML attribute's width in percentage on a custom component

What about the opposite?  Does anyone know of a way to set a width in actionscript to use percentages? i.e.:

datagridcolumnVar.width = 25%;

won't work.

I am actually having the same problem -

I have a canvas with the width set to 100%. If I try and get the
width in pixels through AS it returns 0.

If I try the same thing through mxml it works fine.

So this in AS:
public function getMiddle():Number {
var x:Number;
x = mainCanvas.width*.5;
return x;
}

--returns 0

in MXML:
<mx:Label text="{mainCanvas.width*.5}"/>

--returns the amount in pixels.

Anyone out there know how to get the pixel value though AS?

Angela.
