524 // possible to hide it when the application is active. To ensure that
525 // this work properly, the menu bar and window constraining are
526 // deferred until the application becomes active.
527 //
528 // Even though it's not possible to manually move a window above the
529 // top of the screen, it is allowed if it's done programmatically,
530 // when the menu is hidden. This allows the editable area to cover the
531 // full screen height.
532 //
533 // Test cases
534 // ----------
535 //
536 // Use the following extra files:
537 //
538 // init.el:
539 // ;; Hide menu and place frame slightly above the top of the screen.
540 // (setq ns-auto-hide-menu-bar t)
541 // (set-frame-position (selected-frame) 0 -20)
542 //
543 // Test 1:
544 //
545 // emacs -Q -l init.el
546 //
547 // Result: No menu bar, and the title bar should be above the screen.
548 //
549 // Test 2:
550 //
551 // emacs -Q
552 //
553 // Result: Menu bar visible, frame placed immediately below the menu.
