Normally when maximizing a window it will cover the available geometry
of the screen, as represented by QScreen::availableGeometry(), which
typically excludes status/menu bars and application launchers.
On some platforms it may still be possible to place windows in the areas
of the screen that are outside of the available geometry, but this will
result in the window being partially covered by (possibly) transparent
system UIs. The new flag allows the user to specify that when maximizing
the window it should try to cover as much as possible of the screen
geometry (in contrast to going full screen, which would typically
hide any system UIs).
For iOS this is a common use-case, as the status bar is transparent,
and the user-interface guidelines for iOS7 and up recommend taking
advantage of the full screen space, while keeping any user-interaction
elements still inside the available geometry of the screen.
