Answer 1

You'll have to explicitly change the size of your StackLayoutPanel. You have to calculate this size yourself.

If each header is 40 pixels high, for example, and you want the displayed child (son) to have 200 pixels to display, you could call stackLayoutPanel.setHeight((40*numChildren + 200)+"px");

If you want it to take up all of the available space before scrolling, you'll have to get fancier in your calculations, but it's a flexible plan!
