513 // by overriding it, it's possible to inhibit this, leaving the window
514 // in it's original position.
515 //
516 // It's possible to hide the menu bar. However, technically, it's only
517 // possible to hide it when the application is active. To ensure that
518 // this work properly, the menu bar and window constraining are
519 // deferred until the application becomes active.
520 //
521 // Even though it's not possible to manually move a window above the
522 // top of the screen, it is allowed if it's done programmatically,
523 // when the menu is hidden. This allows the editable area to cover the
524 // full screen height.
525 //
526 // Test cases
527 // ----------
528 //
529 // Use the following extra files:
530 //
531 // init.el:
532 // ;; Hide menu and place frame slightly above the top of the screen.
533 // (setq ns-auto-hide-menu-bar t)
534 // (set-frame-position (selected-frame) 0 -20)
535 //
536 // Test 1:
537 //
538 // emacs -Q -l init.el
539 //
540 // Result: No menu bar, and the title bar should be above the screen.
541 //
542 // Test 2:
543 //
