496// Window constraining
497// -------------------
498//
499// To ensure that the windows are not placed under the menu bar, they
500// are typically moved by the call-back constrainFrameRect. However,
501// by overriding it, it's possible to inhibit this, leaving the window
502// in it's original position.
503//
504// It's possible to hide the menu bar. However, technically, it's only
505// possible to hide it when the application is active. To ensure that
506// this work properly, the menu bar and window constraining are
507// deferred until the application becomes active.
508//
509// Even though it's not possible to manually move a window above the
510// top of the screen, it is allowed if it's done programmatically,
511// when the menu is hidden. This allows the editable area to cover the
512// full screen height.
513//
514// Test cases
515// ----------
516//
517// Use the following extra files:
518//
519// init.el:
520// ;; Hide menu and place frame slightly above the top of the screen.
521// (setq ns-auto-hide-menu-bar t)
522// (set-frame-position (selected-frame) 0 -20)
523//
524// Test 1:
525//
526// emacs -Q -l init.el
527//
528// Result: No menu bar, and the title bar should be above the screen.
529//
530// Test 2:
531//
532// emacs -Q
533//
534// Result: Menu bar visible, frame placed immediately below the menu.
