That information will be maintained by the widget toolkit. I know GTK
uses one X server window for many different widgets at once, and it
might also be the case for QT and others.

When you lick the tabs / buttons, the widget toolkit will route the
event to the appropriate code by comparing the coordinates the event was
received at to the widgets it is displaying in that window.
