578 // Window constraining
579 // -------------------
580 //
581 // To ensure that the windows are not placed under the menu bar, they
582 // are typically moved by the call-back constrainFrameRect. However,
583 // by overriding it, it's possible to inhibit this, leaving the window
584 // in it's original position.
585 //
586 // It's possible to hide the menu bar. However, technically, it's only
587 // possible to hide it when the application is active. To ensure that
588 // this work properly, the menu bar and window constraining are
589 // deferred until the application becomes active.
590 //
591 // Even though it's not possible to manually move a window above the
592 // top of the screen, it is allowed if it's done programmatically,
593 // when the menu is hidden. This allows the editable area to cover the
594 // full screen height.
595 //
596 // Test cases
597 // ----------
598 //
599 // Use the following extra files:
600 //
601 // init.el:
602 // ;; Hide menu and place frame slightly above the top of the screen.
603 // (setq ns-auto-hide-menu-bar t)
604 // (set-frame-position (selected-frame) 0 -20)
605 //
606 // Test 1:
607 //
608 // emacs -Q -l init.el
609 //
610 // Result: No menu bar, and the title bar should be above the screen.
611 //
612 // Test 2:
613 //
614 // emacs -Q
615 //
616 // Result: Menu bar visible, frame placed immediately below the menu.
