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

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