[flexcoders] adding a label to a Panel header?

[fb6668]

Hi, I've extended the Panel container, and would now like to add a
second text field to the header.

I currently have code which has added am expand/contract button to the
header, using:

rawChildren.addChild(btStateUp);
rawChildren.addChild(btStateDown);

but when I try to add a label, as follows, nothing is displayed:

in createChildren():

lblTotal = new Label();
lblTotal.text = "£200**";
rawChildren.addChild(lblTotal);

and in updateDisplayList():

lblTotal.move(unscaledWidth - lblTotal.width - 10, y);

Can anyone shed any light why it's not showing? I can include the
whole script if required, but it's based on MaxRestorePanel which is
in the FlexGrocer app.

Thanks!
