The TABSET frame type defines a container for a set of tabbed page frames.
Any normal frame defined directly within a TABSET frame will become a tabbed page frame, with its tag text displayed in the tab; selecting a tab will bring the tabbed page frame to the front, and hide the previously shown tabbed page frame. A page SHOWN event is raised for the tabbed page frame whenever the user interactively selects a new page tab.
