495// Window constraining
496// -------------------
497//
498// To ensure that the windows are not placed under the menu bar, they
499// are typically moved by the call-back constrainFrameRect. However,
500// by overriding it, it's possible to inhibit this, leaving the window
501// in it's original position.
502//
503// It's possible to hide the menu bar. However, technically, it's only
504// possible to hide it when the application is active. To ensure that
505// this work properly, the menu bar and window constraining are
506// deferred until the application becomes active.
507//
508// Even though it's not possible to manually move a window above the
509// top of the screen, it is allowed if it's done programmatically,
510// when the menu is hidden. This allows the editable area to cover the
511// full screen height.
512//
513// Test cases
514// ----------
515//
516// Use the following extra files:
517//
518// init.el:
519// ;; Hide menu and place frame slightly above the top of the screen.
520// (setq ns-auto-hide-menu-bar t)
521// (set-frame-position (selected-frame) 0 -20)
522//
523// Test 1:
524//
525// emacs -Q -l init.el
526//
527// Result: No menu bar, and the title bar should be above the screen.
528//
529// Test 2:
530//
531// emacs -Q
532//
533// Result: Menu bar visible, frame placed immediately below the menu.
