560 // Window constraining
561 // -------------------
562 //
563 // To ensure that the windows are not placed under the menu bar, they
564 // are typically moved by the call-back constrainFrameRect. However,
565 // by overriding it, it's possible to inhibit this, leaving the window
566 // in it's original position.
567 //
568 // It's possible to hide the menu bar. However, technically, it's only
569 // possible to hide it when the application is active. To ensure that
570 // this work properly, the menu bar and window constraining are
571 // deferred until the application becomes active.
572 //
573 // Even though it's not possible to manually move a window above the
574 // top of the screen, it is allowed if it's done programmatically,
575 // when the menu is hidden. This allows the editable area to cover the
576 // full screen height.
577 //
578 // Test cases
579 // ----------
580 //
581 // Use the following extra files:
582 //
583 // init.el:
584 // ;; Hide menu and place frame slightly above the top of the screen.
585 // (setq ns-auto-hide-menu-bar t)
586 // (set-frame-position (selected-frame) 0 -20)
587 //
588 // Test 1:
589 //
590 // emacs -Q -l init.el
591 //
592 // Result: No menu bar, and the title bar should be above the screen.
593 //
594 // Test 2:
595 //
596 // emacs -Q
597 //
598 // Result: Menu bar visible, frame placed immediately below the menu.
