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