619 // are typically moved by the call-back constrainFrameRect. However,
620 // by overriding it, it's possible to inhibit this, leaving the window
621 // in it's original position.
622 //
623 // It's possible to hide the menu bar. However, technically, it's only
624 // possible to hide it when the application is active. To ensure that
625 // this work properly, the menu bar and window constraining are
626 // deferred until the application becomes active.
627 //
628 // Even though it's not possible to manually move a window above the
629 // top of the screen, it is allowed if it's done programmatically,
630 // when the menu is hidden. This allows the editable area to cover the
631 // full screen height.
632 //
633 // Test cases
634 // ----------
635 //
636 // Use the following extra files:
637 //
638 // init.el:
639 // ;; Hide menu and place frame slightly above the top of the screen.
640 // (setq ns-auto-hide-menu-bar t)
641 // (set-frame-position (selected-frame) 0 -20)
642 //
643 // Test 1:
644 //
645 // emacs -Q -l init.el
646 //
647 // Result: No menu bar, and the title bar should be above the screen.
648 //
649 // Test 2:
650 //
651 // emacs -Q
652 //
653 // Result: Menu bar visible, frame placed immediately below the menu.
