535// Window constraining
536// -------------------
537//
538// To ensure that the windows are not placed under the menu bar, they
539// are typically moved by the call-back constrainFrameRect. However,
540// by overriding it, it's possible to inhibit this, leaving the window
541// in it's original position.
542//
543// It's possible to hide the menu bar. However, technically, it's only
544// possible to hide it when the application is active. To ensure that
545// this work properly, the menu bar and window constraining are
546// deferred until the application becomes active.
547//
548// Even though it's not possible to manually move a window above the
549// top of the screen, it is allowed if it's done programmatically,
550// when the menu is hidden. This allows the editable area to cover the
551// full screen height.
552//
553// Test cases
554// ----------
555//
556// Use the following extra files:
557//
558// init.el:
559// ;; Hide menu and place frame slightly above the top of the screen.
560// (setq ns-auto-hide-menu-bar t)
561// (set-frame-position (selected-frame) 0 -20)
562//
563// Test 1:
564//
565// emacs -Q -l init.el
566//
567// Result: No menu bar, and the title bar should be above the screen.
568//
569// Test 2:
570//
571// emacs -Q
572//
573// Result: Menu bar visible, frame placed immediately below the menu.
