634 // -------------------

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