Hi,
For one I see you are missing;
graphics.clear();
Try that, I don't think you are erasing the old color.
Peace, Mike
PS hehe I was thinking about something else when I responded and forgot the
internal icon is typed IFlexDisplayObject.

Well here's the deal. I've created an simple icon class that draws a
red square like this:
package components {
import mx.skins.ProgrammaticSkin;
public class Icon extends ProgrammaticSkin {
private var iconColor:uint = 0xFF0000;
public function Icon() {
super();
}
public function set color(value:uint):void {
iconColor = value;
invalidateDisplayList();
}
override public function get measuredHeight():Number {
return 16;
}
override public function get measuredWidth():Number {
return 16;
}
override protected function
updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void {
super.updateDisplayList(unscaledWidth, unscaledHeight);
graphics.beginFill(iconColor, 1);
graphics.drawRect(0, 0, unscaledWidth, unscaledHeight);
graphics.endFill();
}
}
}
I can place this icon in a Panel like this:
<mx:Panel id="myPanel" titleIcon="{Icon}" ... >
So far so good -- the red square is drawn in the top left corner of
the title area and it appears that I can call the color setter
function like this:
myPanel.titleIcon.color = 0x00FF00;
But when I do this the icon color never changes. It appears that the
calling invalidateDisplayList() never results in a call to
updateDisplayList().
Any ideas?
Paul
