550 // Window constraining
551 // -------------------
552 //
553 // To ensure that the windows are not placed under the menu bar, they
554 // are typically moved by the call-back constrainFrameRect. However,
555 // by overriding it, it's possible to inhibit this, leaving the window
556 // in it's original position.
557 //
558 // It's possible to hide the menu bar. However, technically, it's only
559 // possible to hide it when the application is active. To ensure that
560 // this work properly, the menu bar and window constraining are
561 // deferred until the application becomes active.
562 //
563 // Even though it's not possible to manually move a window above the
564 // top of the screen, it is allowed if it's done programmatically,
565 // when the menu is hidden. This allows the editable area to cover the
566 // full screen height.
567 //
568 // Test cases
569 // ----------
570 //
571 // Use the following extra files:
572 //
573 // init.el:
574 // ;; Hide menu and place frame slightly above the top of the screen.
575 // (setq ns-auto-hide-menu-bar t)
576 // (set-frame-position (selected-frame) 0 -20)
577 //
578 // Test 1:
579 //
580 // emacs -Q -l init.el
581 //
582 // Result: No menu bar, and the title bar should be above the screen.
583 //
584 // Test 2:
585 //
586 // emacs -Q
587 //
588 // Result: Menu bar visible, frame placed immediately below the menu.
