如何在MFC单文档程序中添加菜单函数? 我设计了一个电子时钟的程序,但是题目要求用户可以自己定制钟表的颜色,指针的颜色,以及个人喜欢的属性,请教各位大牛应该在哪里加入菜单函数?加什么呢?谢谢!大一新生的程序设计作业,很急! 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 (1)单文档程序不是有菜单栏嘛?你创建一个菜单资源,然后在菜单栏load菜单资源的时候换成你的菜单资源的ID就可以了;(2)你可以已右键菜单的方式来实现:CXXXXView::OnRightButtonDown(){ CPoint point; CMenu menu; menu.LoadMenu(IDR_RBUTTON_MENU); CMenu *pMenu = menu.GetSubMenu(1); ASSERT(pMenu != NULL); GetCursorPos(&point); pMenu->TrackPopupMenu(TPM_LEFTALIGN,point.x,point.y,this);} 直接在资源Menu中添加菜单项,然后响应WM_COMMAND命令消息 好吧,我可能描述能力有限,我再详细说一下,现在我已经在菜单项处增加了ONCOMMAND命令,现在需要写这个命令消息,我想完成的功能是:在这个消息中可以做到调用ONDRAW函数,使其中图形的颜色按命令改变,那应该如何写这个调用ONDRAW的函数呢?我是个初学者,希望大家可以帮帮我~~~谢谢了这个是我的view.cpp文件的代码:MyClockView.cpp// MyClockView.cpp : implementation of the CMyClockView class//#include "stdafx.h"#include "MyClock.h"#include "MyClockDoc.h"#include "MyClockView.h"#include "Math.h"#ifdef _DEBUG#define new DEBUG_NEW#undef THIS_FILEstatic char THIS_FILE[] = __FILE__;#endif/////////////////////////////////////////////////////////////////////////////// CMyClockViewIMPLEMENT_DYNCREATE(CMyClockView, CView)BEGIN_MESSAGE_MAP(CMyClockView, CView) //{{AFX_MSG_MAP(CMyClockView) ON_WM_CREATE() ON_WM_TIMER() //}}AFX_MSG_MAP // Standard printing commands ON_COMMAND(ID_FILE_PRINT, CView::OnFilePrint) ON_COMMAND(ID_FILE_PRINT_DIRECT, CView::OnFilePrint) ON_COMMAND(ID_FILE_PRINT_PREVIEW, CView::OnFilePrintPreview)END_MESSAGE_MAP()/////////////////////////////////////////////////////////////////////////////// CMyClockView construction/destructionCMyClockView::CMyClockView(){ // TODO: add construction code here}CMyClockView::~CMyClockView(){}BOOL CMyClockView::PreCreateWindow(CREATESTRUCT& cs){ // TODO: Modify the Window class or styles here by modifying // the CREATESTRUCT cs return CView::PreCreateWindow(cs);}/////////////////////////////////////////////////////////////////////////////// CMyClockView drawingvoid CMyClockView::OnDraw(CDC* pDC){ CMyClockDoc* pDoc = GetDocument();
