523 // are typically moved by the call-back constrainFrameRect. However,
524 // by overriding it, it's possible to inhibit this, leaving the window
525 // in it's original position.
526 //
527 // It's possible to hide the menu bar. However, technically, it's only
528 // possible to hide it when the application is active. To ensure that
529 // this work properly, the menu bar and window constraining are
530 // deferred until the application becomes active.
531 //
532 // Even though it's not possible to manually move a window above the
533 // top of the screen, it is allowed if it's done programmatically,
534 // when the menu is hidden. This allows the editable area to cover the
535 // full screen height.
536 //
537 // Test cases
538 // ----------
539 //
540 // Use the following extra files:
541 //
542 // init.el:
543 // ;; Hide menu and place frame slightly above the top of the screen.
544 // (setq ns-auto-hide-menu-bar t)
545 // (set-frame-position (selected-frame) 0 -20)
546 //
547 // Test 1:
548 //
549 // emacs -Q -l init.el
550 //
551 // Result: No menu bar, and the title bar should be above the screen.
552 //
553 // Test 2:
554 //
555 // emacs -Q
556 //
