BCG例子BCGPExplorer：
1.BCG的菜单、工具栏、动画图标和地址栏
这是BCG的主要特色，也比较繁琐。

（1）如果要支持自定义工具。

首先在String表定义入口ID：ID_TOOLS_ENTRY，与某菜单项关联。然后定义连续的ID，如ID_USER_TOOL1、ID_USER_TOOL2......。

在App下增加 

EnableUserTools (ID_TOOLS_ENTRY, ID_USER_TOOL1, ID_USER_TOOL10);

（2）主要是修改CMainFrame

头文件声明

 CBCGPMenuBar  m_wndMenuBar;
  CBCGPStatusBar m_wndStatusBar;
  CBCGPToolBar  m_wndToolBar;
  CBCGPReBar   m_wndReBar;  //菜单、工具栏、地址栏的容器
  CBCGPAnimCtrl m_wndAnimate;//动画控件
  CComboBoxEx  m_wndAddress;//地址栏

增加响应自定义工具的消息函数OnViewCustomize

手动添加消息响应

 afx_msg LRESULT OnToolbarReset(WPARAM,LPARAM);
  afx_msg LRESULT OnToolbarContextMenu(WPARAM,LPARAM);

 虚函数

virtual BOOL OnShowPopupMenu (CBCGPPopupMenu* pMenuPopup);

  ON_REGISTERED_MESSAGE(BCGM_TOOLBARMENU, OnToolbarContextMenu)
