556 // Window constraining
557 // -------------------
558 //
559 // To ensure that the windows are not placed under the menu bar, they
560 // are typically moved by the call-back constrainFrameRect. However,
561 // by overriding it, it's possible to inhibit this, leaving the window
562 // in it's original position.
563 //
564 // It's possible to hide the menu bar. However, technically, it's only
565 // possible to hide it when the application is active. To ensure that
566 // this work properly, the menu bar and window constraining are
567 // deferred until the application becomes active.
568 //
569 // Even though it's not possible to manually move a window above the
570 // top of the screen, it is allowed if it's done programmatically,
571 // when the menu is hidden. This allows the editable area to cover the
572 // full screen height.
573 //
574 // Test cases
575 // ----------
576 //
577 // Use the following extra files:
578 //
579 // init.el:
580 // ;; Hide menu and place frame slightly above the top of the screen.
581 // (setq ns-auto-hide-menu-bar t)
582 // (set-frame-position (selected-frame) 0 -20)
583 //
584 // Test 1:
585 //
586 // emacs -Q -l init.el
587 //
588 // Result: No menu bar, and the title bar should be above the screen.
589 //
590 // Test 2:
591 //
592 // emacs -Q
593 //
594 // Result: Menu bar visible, frame placed immediately below the menu.
