508// Window constraining
509// -------------------
510//
511// To ensure that the windows are not placed under the menu bar, they
512// are typically moved by the call-back constrainFrameRect. However,
513// by overriding it, it's possible to inhibit this, leaving the window
514// in it's original position.
515//
516// It's possible to hide the menu bar. However, technically, it's only
517// possible to hide it when the application is active. To ensure that
518// this work properly, the menu bar and window constraining are
519// deferred until the application becomes active.
520//
521// Even though it's not possible to manually move a window above the
522// top of the screen, it is allowed if it's done programmatically,
523// when the menu is hidden. This allows the editable area to cover the
524// full screen height.
525//
526// Test cases
527// ----------
528//
529// Use the following extra files:
530//
531// init.el:
532// ;; Hide menu and place frame slightly above the top of the screen.
533// (setq ns-auto-hide-menu-bar t)
534// (set-frame-position (selected-frame) 0 -20)
535//
536// Test 1:
537//
538// emacs -Q -l init.el
539//
540// Result: No menu bar, and the title bar should be above the screen.
541//
542// Test 2:
543//
544// emacs -Q
545//
546// Result: Menu bar visible, frame placed immediately below the menu.
