Carbonを捨て去る時が来た！？

フルスクリーンでメニューとDockを隠して且つにゅるんとメニューバーを表示するにはCarbon.frameworkの関数

SetSystemUIMode(kUIModeAllHidden, kUIOptionAutoShowMenuBar);

を使います。見ての通りカーボンで関数です。
しかもDockはにゅるんと出てきません。

が、が、が！！
Snow Leopardだと

-[NSApplication setPresentationOptions:]

#if MAC_OS_X_VERSION_MAX_ALLOWED >= MAC_OS_X_VERSION_10_6
/* Flags that comprise an application's presentationOptions */
enum {
    NSApplicationPresentationDefault                    = 0,
    NSApplicationPresentationAutoHideDock               = (1 <<  0),    // Dock appears when moused to
    NSApplicationPresentationHideDock                   = (1 <<  1),    // Dock is entirely unavailable

    NSApplicationPresentationAutoHideMenuBar            = (1 <<  2),    // Menu Bar appears when moused to
    NSApplicationPresentationHideMenuBar                = (1 <<  3),    // Menu Bar is entirely unavailable

    NSApplicationPresentationDisableAppleMenu           = (1 <<  4),    // all Apple menu items are disabled
    NSApplicationPresentationDisableProcessSwitching    = (1 <<  5),    // Cmd+Tab UI is disabled
    NSApplicationPresentationDisableForceQuit           = (1 <<  6),    // Cmd+Opt+Esc panel is disabled
    NSApplicationPresentationDisableSessionTermination  = (1 <<  7),    // PowerKey panel and Restart/Shut Down/Log Out disabled
    NSApplicationPresentationDisableHideApplication     = (1 <<  8),    // Application "Hide" menu item is disabled
    NSApplicationPresentationDisableMenuBarTransparency = (1 <<  9)     // Menu Bar's transparent appearance is disabled
};
#endif
typedef NSUInteger NSApplicationPresentationOptions;

なんてのが使えます！！！

使えるんだって！
しかも

    NSApplicationPresentationAutoHideDock               = (1 <<  0),    // Dock appears when moused to

なんていう素敵機能まで！

で、なんでスノレパだけ！？　まだ捨て去れないんじゃないの？
