This is also doable with a PagePanel.
The tabs on the left can be created with BevelButtons or Canvas with pictures prepared in such product as Photoshop, or generated on the fly with http://documentation.xojo.com/index.php/Object2D and rotated.

The bevel button with a rotated text image may work with the pagepanel. Thanks for the inspiration
