640 // are typically moved by the call-back constrainFrameRect. However,
641 // by overriding it, it's possible to inhibit this, leaving the window
642 // in it's original position.
643 //
644 // It's possible to hide the menu bar. However, technically, it's only
645 // possible to hide it when the application is active. To ensure that
646 // this work properly, the menu bar and window constraining are
647 // deferred until the application becomes active.
648 //
649 // Even though it's not possible to manually move a window above the
650 // top of the screen, it is allowed if it's done programmatically,
651 // when the menu is hidden. This allows the editable area to cover the
652 // full screen height.
653 //
654 // Test cases
655 // ----------
656 //
657 // Use the following extra files:
658 //
659 // init.el:
660 // ;; Hide menu and place frame slightly above the top of the screen.
661 // (setq ns-auto-hide-menu-bar t)
662 // (set-frame-position (selected-frame) 0 -20)
663 //
664 // Test 1:
665 //
666 // emacs -Q -l init.el
667 //
668 // Result: No menu bar, and the title bar should be above the screen.
669 //
670 // Test 2:
671 //
672 // emacs -Q
673 //
674 // Result: Menu bar visible, frame placed immediately below the menu.
