It doesn't directly. It tells the window manager that it wants to go
full screen. The window manager resizes the window, which causes a
resize event to be sent to the application. The application then asks
the layout manager to recompute the layout based on the new window size
(the latter will probably be managed automatically by the framework, so
the programmer doesn't have to write code for that, but it's still part
of the application).
