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
