499// Window constraining
500// -------------------
501//
502// To ensure that the windows are not placed under the menu bar, they
503// are typically moved by the call-back constrainFrameRect. However,
504// by overriding it, it's possible to inhibit this, leaving the window
505// in it's original position.
506//
507// It's possible to hide the menu bar. However, technically, it's only
508// possible to hide it when the application is active. To ensure that
509// this work properly, the menu bar and window constraining are
510// deferred until the application becomes active.
511//
512// Even though it's not possible to manually move a window above the
513// top of the screen, it is allowed if it's done programmatically,
514// when the menu is hidden. This allows the editable area to cover the
515// full screen height.
516//
517// Test cases
518// ----------
519//
520// Use the following extra files:
521//
522// init.el:
523// ;; Hide menu and place frame slightly above the top of the screen.
524// (setq ns-auto-hide-menu-bar t)
525// (set-frame-position (selected-frame) 0 -20)
526//
527// Test 1:
528//
529// emacs -Q -l init.el
530//
531// Result: No menu bar, and the title bar should be above the screen.
532//
533// Test 2:
534//
535// emacs -Q
536//
537// Result: Menu bar visible, frame placed immediately below the menu.
