1.前言

最近发现读者对我的mfc美化的专栏比较感兴趣，因此在这里进行续写，这里我会计划写几个连续的篇章，包括对MFC按钮的美化，菜单栏的美化，标题栏的美化，list列表的美化，直到最后形成一个完整的成品效果。

2.最终效果展示

点击启动按钮之后，能响应功能。

博主不会UI设计图片显示的效果比较差，用更好的图片贴上去，就能显示更好的效果的

3.思路分析

1.使用我们设计好的图片，来美化按钮。把图片贴到按钮上

2.创建一个按钮类，继承CButton,来重绘按钮

3.核心还是重写了 DrawItem，函数来实现重绘的效果

4.实现过程

1.在MFC的界面那里，创建两个按钮，启动和停止按钮。

2.找到按钮的属性那里，把所有者描述改成true,不然重绘是不能成功的，这一步是一定要做的

3.核心代码

头文件里面声明按钮变量

public:CMyButton m_button_start;CMyButton m_button_stop;afx_msg void OnBnClickedButton2();afx_msg void OnBnClickedButton1();

OnInitDialog()函数

BOOL CMFCDrawnTitleDlg::OnInitDialog()
{CDialogEx::OnInitDialog();// 将“关于...”菜单项添加到系统菜单中。// IDM_ABOUTBOX 必须在系统命令范围内。ASSERT((IDM_ABOUTBOX & 0xFFF0) == IDM_ABOUTBOX);ASSERT(IDM_ABOUTBOX < 0xF000);CMenu* pSysMenu = GetSystemMenu(FALSE);if (pSysMenu != nullptr){BOOL bNameValid;CString strAboutMenu;bNameValid = strAboutMenu.LoadString(IDS_ABOUTBOX);ASSERT(bNameValid);if (!strAboutMenu.IsEmpty()){pSysMenu->AppendMenu(MF_SEPARATOR);pSysMenu->AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);}}// 设置此对话框的图标。  当应用程序主窗口不是对话框时，框架将自动//  执行此操作SetIcon(m_hIcon, TRUE);			// 设置大图标SetIcon(m_hIcon, FALSE);		// 设置小图标// TODO: 在此添加额外的初始化代码//退出按钮绘制CRect rtBtnClo;GetClientRect(&rtBtnClo);rtBtnClo.left = rtBtnClo.right - 20;m_btnExit.SetImagePath(_T(".\\res\\icon_popup_off.png"), _T(".\\res\\icon_popup_off.png"), _T(".\\res\\icon_popup_off.png"));m_btnExit.InitMyButton(rtBtnClo.left, 5, 16, 16, true);//最大化按钮绘制GetClientRect(&rtBtnClo);rtBtnClo.left = rtBtnClo.right - 50;m_btnMax.SetImagePath(_T(".\\res\\icon_square.png"), _T(".\\res\\icon_square.png"), _T(".\\res\\icon_square.png"));m_btnMax.InitMyButton(rtBtnClo.left, 5, 16, 16, true);//最小化按钮// GetClientRect(&rtBtnClo);rtBtnClo.left = rtBtnClo.right - 80;m_btnMin.SetImagePath(_T(".\\res\\icon_minimiz.png"), _T(".\\res\\icon_minimiz.png"), _T(".\\res\\icon_minimiz.png"));m_btnMin.InitMyButton(rtBtnClo.left, 5, 16, 16, true);return TRUE;  // 除非将焦点设置到控件，否则返回 TRUE
}

5.button重绘的头文件和cpp文件

mybutton.h

pch.h, 和framework.h这两个文件的路径，可以改的。根据你的项目文件实际放置情况

#pragma once#include <afxwin.h>
#include "../pch.h"
#include "../framework.h"
// CMyButtonclass CMyButton : public CButton
{DECLARE_DYNAMIC(CMyButton)public:CMyButton();virtual ~CMyButton();protected://正常状态图像路径CString m_strNormalImgPath;//按下状态图像路径CString m_strPressImgPath;//悬浮状态图像路径CString m_strFloatImgPath;//正常状态图像CImage m_imgNormal;//按下状态图像CImage m_imgPress;//悬浮状态图像CImage m_imgFloat;//窗口背景图片CImage m_BkImg;public://设置按钮图片路径void SetImagePath(CString strNoramlImgPath, CString strPressImgPath, CString strFloatImgPath);//初始化按钮，主要是调整按钮的位置，处理透明色  bool InitMyButton(int nX/*左上角X坐标*/, int nY/*左上角Y坐标*/, int nW/*图像宽*/, int nH/*图像高*/, bool bIsPng/*是否是PNG图片*/);//自绘制函数  void DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct);//初始化窗口背景void SetBkImg(CString strBkImg);//释放图片资源，方便最大化 void ReleaseImg();
protected://光标是否在窗口内BOOL m_bIsInWnd;DECLARE_MESSAGE_MAP()
