511// Window constraining
512// -------------------
513//
514// To ensure that the windows are not placed under the menu bar, they
515// are typically moved by the call-back constrainFrameRect. However,
516// by overriding it, it's possible to inhibit this, leaving the window
517// in it's original position.
518//
519// It's possible to hide the menu bar. However, technically, it's only
520// possible to hide it when the application is active. To ensure that
521// this work properly, the menu bar and window constraining are
522// deferred until the application becomes active.
523//
524// Even though it's not possible to manually move a window above the
525// top of the screen, it is allowed if it's done programmatically,
526// when the menu is hidden. This allows the editable area to cover the
527// full screen height.
528//
529// Test cases
530// ----------
531//
532// Use the following extra files:
533//
534// init.el:
535// ;; Hide menu and place frame slightly above the top of the screen.
536// (setq ns-auto-hide-menu-bar t)
537// (set-frame-position (selected-frame) 0 -20)
538//
539// Test 1:
540//
541// emacs -Q -l init.el
542//
543// Result: No menu bar, and the title bar should be above the screen.
544//
545// Test 2:
546//
547// emacs -Q
548//
549// Result: Menu bar visible, frame placed immediately below the menu.
