Try doing something like this in your itemRenderer, and see if it works:
private var _widthChanged:Boolean;
private var _newWidth:int;
override public function set explicitWidth(value:int):void {
super.explicitWidth = value;
_widthChanged = true;
_newWidth = value;
invalidateProperties();
}
override protected function commitProperties():void {
if (_widthChanged) {
width = _newWidth;
_widthChanged= false;
//if the itemRender is not actually a Text control,
//but instead the text control is a child
theTextControl.validateNow();
}
super.commitProperties();
}
If that doesn't work, try checking the text of the control and look at its
internal text field and how big it thinks it is. You should be able to see
these values in the debugger if you set a break point, even if the variables
are not exposed (I think you may need to turn something on from the menu of the
variables window to enable this).
