Hmm. When I had this problem, addrow() refused to work for me also just so you know.

Trying changing the GuiTextListCtrl to GuiTreeViewCtrl and change the addrow's to addnode's
(Just so you can see if it works. Infact, you can even use a treeviewctrl as a textlist if you have to.. Just remove the first line and don't add any child nodes to any root node. Then it should look identical (but this is only incase GuiTextListCtrl just refuses to work)

Also try changing it to a simple control like a GuiBitmapCtrl and set the image just so you know that controls are being placed in the container and actually take up your specified size.
