537 // -------------------
538 //
539 // To ensure that the windows are not placed under the menu bar, they
540 // are typically moved by the call-back constrainFrameRect. However,
541 // by overriding it, it's possible to inhibit this, leaving the window
542 // in it's original position.
543 //
544 // It's possible to hide the menu bar. However, technically, it's only
545 // possible to hide it when the application is active. To ensure that
546 // this work properly, the menu bar and window constraining are
547 // deferred until the application becomes active.
548 //
549 // Even though it's not possible to manually move a window above the
550 // top of the screen, it is allowed if it's done programmatically,
551 // when the menu is hidden. This allows the editable area to cover the
552 // full screen height.
553 //
554 // Test cases
555 // ----------
556 //
557 // Use the following extra files:
558 //
559 // init.el:
560 // ;; Hide menu and place frame slightly above the top of the screen.
561 // (setq ns-auto-hide-menu-bar t)
562 // (set-frame-position (selected-frame) 0 -20)
563 //
564 // Test 1:
565 //
566 // emacs -Q -l init.el
567 //
568 // Result: No menu bar, and the title bar should be above the screen.
569 //
570 // Test 2:
571 //
572 // emacs -Q
573 //
574 // Result: Menu bar visible, frame placed immediately below the menu.
