I agree, styles are better for styles. Again, just answering some ones
question. What I have learned in flex is, there a re a lot of ways to climb
the mountain.
Ok, because I'm a big loser and I don't like using mx_internal... sorry
that I'm so lame Mike
Thats a joke right? I don't like it either unless it gets me somewhere.
if(this.parent!= null && this.parent is UIComponent) {
if((this.parent as UIComponent).getStyle("arrowColor")) {
_color = (this.parent as
UIComponent).getStyle("arrowColor");
}
}
You could replace that block with;
var color:uint;
if (parent is IStyleClient)
color = IStyleClient(parent).getStyle("arrowColor");
if (!isNaN(color))
_color = color;
Peace, Mike

use mx_internal.
Basically three things change from Mikes example.
private function changeIcon(event:MouseEvent):void {
myPanel.setStyle("arrowColor", 0xff0000);
}
I set a style rather than a property on an object we can't safely access.
on the Icon class I add this metadata
[Style(name="arrowColor",type="uint",format="Color",inherit="yes")]
and updateDisplayList becomes this
override protected function
updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void {
super.updateDisplayList(unscaledWidth, unscaledHeight);
if(this.parent!= null && this.parent is UIComponent) {
if((this.parent as UIComponent).getStyle("arrowColor")) {
_color = (this.parent as
UIComponent).getStyle("arrowColor");
}
}
graphics.clear();
graphics.beginFill(_color, 1);
graphics.drawRect(0, 0, unscaledWidth, unscaledHeight);
graphics.endFill();
}
Might be possible to improve the logic in the part where it gets the
style.

You can find more by solving the problem then by 'asking the question'.
