554 // Window constraining
555 // -------------------
556 //
557 // To ensure that the windows are not placed under the menu bar, they
558 // are typically moved by the call-back constrainFrameRect. However,
559 // by overriding it, it's possible to inhibit this, leaving the window
560 // in it's original position.
561 //
562 // It's possible to hide the menu bar. However, technically, it's only
563 // possible to hide it when the application is active. To ensure that
564 // this work properly, the menu bar and window constraining are
565 // deferred until the application becomes active.
566 //
567 // Even though it's not possible to manually move a window above the
568 // top of the screen, it is allowed if it's done programmatically,
569 // when the menu is hidden. This allows the editable area to cover the
570 // full screen height.
571 //
572 // Test cases
573 // ----------
574 //
575 // Use the following extra files:
576 //
577 // init.el:
578 // ;; Hide menu and place frame slightly above the top of the screen.
579 // (setq ns-auto-hide-menu-bar t)
580 // (set-frame-position (selected-frame) 0 -20)
581 //
582 // Test 1:
583 //
584 // emacs -Q -l init.el
585 //
586 // Result: No menu bar, and the title bar should be above the screen.
587 //
588 // Test 2:
589 //
590 // emacs -Q
591 //
592 // Result: Menu bar visible, frame placed immediately below the menu.
