C++ InternalWindowRecPtr::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.
