I have an arraycollection called groupsdata....
groupsdata.getItemAt(f).state = true/false
And then in my itemRenderer, I override like this:
override public function set data(value:Object):void {
super.data = value;
if ( !value ) { return; }
// remove check box from child nodes if present
if ( !value.toplevel && this.getChildByName("checkbox") ) {
this.removeChild( this.getChildByName("checkbox") ); }
}
override protected function updateDisplayList(unscaledWidth:Number,
unscaledHeight:Number):void
{
super.updateDisplayList(unscaledWidth, unscaledHeight);
if(super.data)
{
if (super.icon != null)
{
checkBox.x = super.icon.x;
checkBox.y = 12;
super.icon.x = checkBox.x + checkBox.width + 17;
super.label.x = super.icon.x + super.icon.width + 3;
checkBox.selected = super.data.state;
}
else
{
checkBox.x = super.label.x;
checkBox.y = 12;
super.label.x = checkBox.x + checkBox.width + 17;
checkBox.selected = super.data.state;
}
}
}
So it looks like the data object is getting set correctly, but
updateDisplayList isn't getting called when the data is refreshed - but
it does get called on mouse over.
thanks again for the help!
