505 // possible to hide it when the application is active. To ensure that
506 // this work properly, the menu bar and window constraining are
507 // deferred until the application becomes active.
508 //
509 // Even though it's not possible to manually move a window above the
510 // top of the screen, it is allowed if it's done programmatically,
511 // when the menu is hidden. This allows the editable area to cover the
512 // full screen height.
513 //
514 // Test cases
515 // ----------
516 //
517 // Use the following extra files:
518 //
519 // init.el:
520 // ;; Hide menu and place frame slightly above the top of the screen.
521 // (setq ns-auto-hide-menu-bar t)
522 // (set-frame-position (selected-frame) 0 -20)
523 //
524 // Test 1:
525 //
526 // emacs -Q -l init.el
527 //
528 // Result: No menu bar, and the title bar should be above the screen.
529 //
530 // Test 2:
