Adding a child and set to center

Question

I have a very simple script that adds a DisplayObject child to a canvas.... My code is below.
The only thing I cannot figure out how to do is make it to where the canvas is centered, like you would usually do with horizontalCenter="0" verticalCenter="0" ... For some reason or another, these options are not avaialbe in the actionscript...
Can anyone point me in the right direction?
private function AddNewCustomer():void {
        loadCanvas.visible = true;
        var AddCustomer:DisplayObject = new customer_form();
        AddCustomer.width = 500;
        AddCustomer.height = 500;
        AddCustomer.x = 50;
        AddCustomer.y = 50;
        loadCanvas.addChild(AddCustomer);

Answer 1

loadCanvas.setStyle("horizontalCenter", 0);
loadCanvas.setStyle("verticalCenter", 0);
Any property you don't see when you do loadCanvas.xxx you can usually set using setStyle.
Mark this as an answer if it helps out.
Thanks
