635 // are typically moved by the call-back constrainFrameRect. However,
636 // by overriding it, it's possible to inhibit this, leaving the window
637 // in it's original position.
638 //
639 // It's possible to hide the menu bar. However, technically, it's only
640 // possible to hide it when the application is active. To ensure that
641 // this work properly, the menu bar and window constraining are
642 // deferred until the application becomes active.
643 //
644 // Even though it's not possible to manually move a window above the
645 // top of the screen, it is allowed if it's done programmatically,
646 // when the menu is hidden. This allows the editable area to cover the
647 // full screen height.
648 //
649 // Test cases
650 // ----------
651 //
652 // Use the following extra files:
653 //
654 // init.el:
655 // ;; Hide menu and place frame slightly above the top of the screen.
656 // (setq ns-auto-hide-menu-bar t)
657 // (set-frame-position (selected-frame) 0 -20)
658 //
659 // Test 1:
660 //
661 // emacs -Q -l init.el
662 //
663 // Result: No menu bar, and the title bar should be above the screen.
664 //
665 // Test 2:
666 //
667 // emacs -Q
668 //
669 // Result: Menu bar visible, frame placed immediately below the menu.
