504// Window constraining
505// -------------------
506//
507// To ensure that the windows are not placed under the menu bar, they
508// are typically moved by the call-back constrainFrameRect. However,
509// by overriding it, it's possible to inhibit this, leaving the window
510// in it's original position.
511//
512// It's possible to hide the menu bar. However, technically, it's only
513// possible to hide it when the application is active. To ensure that
514// this work properly, the menu bar and window constraining are
515// deferred until the application becomes active.
516//
517// Even though it's not possible to manually move a window above the
518// top of the screen, it is allowed if it's done programmatically,
519// when the menu is hidden. This allows the editable area to cover the
520// full screen height.
521//
522// Test cases
523// ----------
524//
525// Use the following extra files:
526//
527// init.el:
528// ;; Hide menu and place frame slightly above the top of the screen.
529// (setq ns-auto-hide-menu-bar t)
530// (set-frame-position (selected-frame) 0 -20)
531//
532// Test 1:
533//
534// emacs -Q -l init.el
535//
536// Result: No menu bar, and the title bar should be above the screen.
537//
538// Test 2:
539//
540// emacs -Q
541//
542// Result: Menu bar visible, frame placed immediately below the menu.
