引言

本文档介绍了一种使用Windows XP和图标选择样式的自定义绘制菜单的实现方法。要使用此代码，请下载演示项目。演示项目包含3种菜单样式，演示了如何创建XP菜单和图标选择菜单。要将自定义绘制菜单添加到您自己的项目中，请按照以下6个步骤操作

步骤 1

将以下文件添加到您的项目中

• MenuCH.cpp
• MenuCH.h

第二步

在MainFrm.h中 - 在文件顶部添加此行

#include "MenuCH.h"

步骤 3

在MainFrm.h中 - 添加类型为CMenuCH的CMainFrame成员变量。

protected:  // control bar embedded members
    CStatusBar  m_wndStatusBar;
    CToolBar    m_wndToolBar;
    CMenuCH    m_FileMenu, m_EditMenu,
        m_ViewMenu, m_HelpMenu;
    CMenuCH    m_ElementMenu;
    CMenuCH    GraphMenu,ColorMenu;

步骤 4

在MainFrm.cpp中 - 在CMainFrame()中放置以下语句

/////////////////////////////////////////////////////////
// CMainFrame construction/destruction

CMainFrame::CMainFrame()
{
    // TODO: add member initialization code here
    m_FileMenu.CreatePopupMenu();
    m_FileMenu.SetMenuHeight(20);
    m_FileMenu.SetMenuWidth(150);
    m_FileMenu.SetMenuType(MIT_XP);
    m_FileMenu.AppendMenu(MF_ENABLED,ID_FILE_NEW,
        "&New\tCtrl+N",IDB_NEW);
    m_FileMenu.AppendMenu(MF_ENABLED,ID_FILE_OPEN,
        "&Open\tCtrl+O",IDB_OPEN);
    m_FileMenu.AppendMenu(MF_ENABLED,ID_FILE_CLOSE,
        "&Close");
    m_FileMenu.AppendMenu(MF_ENABLED,ID_FILE_SAVE,
        "&Save\tCtrl+S",IDB_SAVE);
    m_FileMenu.AppendMenu(MF_ENABLED,ID_FILE_SAVE_AS,
        "Save &As...");
    m_FileMenu.AppendMenu(MF_SEPARATOR,0,"");
    m_FileMenu.AppendMenu(MF_ENABLED,ID_FILE_PRINT,
        "&Print...",IDB_PRINT);
    m_FileMenu.AppendMenu(MF_ENABLED,ID_FILE_PRINT_PREVIEW,
        "Print Pre&view");
    m_FileMenu.AppendMenu(MF_ENABLED,ID_FILE_PRINT_SETUP,
        "P&rint Setup...");
    m_FileMenu.AppendMenu(MF_SEPARATOR,0,"");
    m_FileMenu.AppendMenu(MF_ENABLED,ID_APP_EXIT,
        "E&xit");

    m_EditMenu.CreatePopupMenu();
    m_EditMenu.SetMenuHeight(20);
    m_EditMenu.SetMenuWidth(165);
    m_EditMenu.SetMenuType(MIT_XP);
    m_EditMenu.AppendMenu(MF_ENABLED,ID_EDIT_UNDO,
        "Redo\tCtrl+Z",IDB_UNDO);
    m_EditMenu.AppendMenu(MF_ENABLED,ID_EDIT_REDO,
        "Undo\tCtrl+Y",IDB_REDO);
    m_EditMenu.AppendMenu(MF_SEPARATOR,0,"");
    m_EditMenu.AppendMenu(MF_ENABLED,ID_EDIT_CUT, 
        "Cut\tCtrl+X",IDB_CUT);
    m_EditMenu.AppendMenu(MF_ENABLED,ID_EDIT_COPY, 
        "Copy\tCtrl+C",IDB_COPY);
    m_EditMenu.AppendMenu(MF_ENABLED,ID_EDIT_PASTE,
        "Paste\tCtrl+V",IDB_PASTE);

    m_ViewMenu.CreatePopupMenu();
    m_ViewMenu.SetMenuHeight(20);
    m_ViewMenu.SetMenuWidth(170);
    m_ViewMenu.SetMenuType(MIT_XP);
    m_ViewMenu.AppendMenu(MF_ENABLED,ID_VIEW_TOOLBAR, 
        "&Toolbar");
    m_ViewMenu.AppendMenu(MF_ENABLED,ID_VIEW_STATUS_BAR,
        "&Status Bar");

    m_HelpMenu.CreatePopupMenu();
    m_HelpMenu.SetMenuHeight(20);
    m_HelpMenu.SetMenuWidth(160);
    m_HelpMenu.SetMenuType(MIT_XP);
    m_HelpMenu.AppendMenu(MF_ENABLED,ID_APP_ABOUT,
        "&About BmpMenuDemo...",IDB_HELP);

    GraphMenu.CreateMenu();
    GraphMenu.AppendMenu(MF_ENABLED,ID_GRAPHPART1BOX,"",
        NULL,AfxGetApp()->LoadIcon(IDI_LINE));
    GraphMenu.AppendMenu(MF_ENABLED,ID_GRAPHPART2BOX,"",
        NULL,AfxGetApp()->LoadIcon(IDI_GRAPHIC));
    GraphMenu.AppendMenu(MF_ENABLED|MF_MENUBREAK,ID_GRAPHPART3BOX,
        "",NULL,AfxGetApp()->LoadIcon(IDI_CIRCLE));
    GraphMenu.AppendMenu(MF_ENABLED,ID_GRAPHPART4BOX,"",
        NULL,AfxGetApp()->LoadIcon(IDI_POLYGON));
    GraphMenu.AppendMenu(MF_ENABLED|MF_MENUBREAK,
        ID_GRAPHPART5BOX,"",NULL,AfxGetApp()->LoadIcon(IDI_ARC));
    GraphMenu.AppendMenu(MF_ENABLED,ID_GRAPHPART6BOX,"",
        NULL,AfxGetApp()->LoadIcon(IDI_TEXT));

    m_ElementMenu.CreatePopupMenu();
    m_ElementMenu.SetMenuType(MIT_ICON);
    m_ElementMenu.AppendMenu(MF_SEPARATOR,0,"");
    m_ElementMenu.AppendMenu(MF_POPUP,
        (UINT)GraphMenu.m_hMenu,"Element");

    ColorMenu.CreatePopupMenu();
    ColorMenu.SetMenuHeight(18);
    ColorMenu.SetMenuWidth(6);
    ColorMenu.SetMenuType(MIT_COLOR);
    char clrValue[64];
    for(int i=1; i<=16; i++)
    {
        wsprintf(clrValue,"%d",rgbColors[i-1]);
        if( i%4 == 1 )
            ColorMenu.AppendMenu(MF_MENUBREAK|MF_ENABLED,
            i,clrValue);
        else
            ColorMenu.AppendMenu(MF_ENABLED,i,clrValue);
    }
    m_ElementMenu.AppendMenu(MF_POPUP,(UINT)ColorMenu.m_hMenu,
        "Colors");
}

步骤 5

在MainFrm.cpp中 - 添加CMainFrame成员函数CreateMenu()并放置以下语句

///////////////////////////////////////////////////////
// CMainFrame message handlers
void CMainFrame::CreateMenu()
{
    CMenu* pMenu = this->GetMenu();
    pMenu->RemoveMenu(0,MF_BYPOSITION);
    pMenu->RemoveMenu(0,MF_BYPOSITION);
    pMenu->RemoveMenu(0,MF_BYPOSITION);
    pMenu->RemoveMenu(0,MF_BYPOSITION);
    pMenu->RemoveMenu(0,MF_BYPOSITION);

    pMenu->InsertMenu(0,MF_BYPOSITION|MF_POPUP,
        (UINT)m_FileMenu.m_hMenu,"&File");  
    pMenu->InsertMenu(1,MF_BYPOSITION|MF_POPUP,
        (UINT)m_EditMenu.m_hMenu,"&Edit");
    pMenu->InsertMenu(2,MF_BYPOSITION|MF_POPUP,
        (UINT)m_ViewMenu.m_hMenu,"&View");
    pMenu->InsertMenu(3,MF_BYPOSITION|MF_POPUP,
        (UINT)m_HelpMenu.m_hMenu,"&Help");
    pMenu->InsertMenu(4,MF_BYPOSITION|MF_POPUP,
        (UINT)m_ElementMenu.m_hMenu,"&Element");
}

步骤 6

在MainFrm.cpp中 - 在CMainFrame::OnCreate中调用CreateMenu()。

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
    if (CFrameWnd::OnCreate(lpCreateStruct) == -1)
        return -1;
    ...

        CreateMenu();
}
