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

553 //
554 // Result: Menu bar visible, frame placed immediately below the menu.
