508 // by overriding it, it's possible to inhibit this, leaving the window
509 // in it's original position.

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