C++ InternalWindowRefPtr::setMenuBar方法代码示例

//.........这里部分代码省略.........
    /******************************************************

      Create MainMenuBar and adds the Menus
      created above to it.

      Also creates several Backgrounds
      to improve MenuBar overall look.
      Both the MenuBar and Menu can have
      Backgrounds; the set up currently
      is to have EmptyBackgrounds in 
      each Menu allowing a single
      overall MenuBar Background which
      is given to the MenuBar itself.

      This can be easily changed by adding
      different Backgrounds to the 
      File and Edit Menus.

Note: The MenuBar is added to the
MainFrame below.
