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