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