MFC程序实现给对话框加入�背景图片
1.插入一个Bitmap的资源图片,如果资源名称为:IDC_BITMAP1
2.在CXXXDialog::OnPaint()中实现:
void CMyDialogDlg::OnPaint() { if (IsIconic()) { CPaintDC dc(this); // 用于绘制的设备上下文 SendMessage(WM_ICONERASEBKGND, reinterpret_cast<WPARAM>(dc.GetSafeHdc()), 0); // 使图标在工作区矩形中居中 int cxIcon = GetSystemMetrics(SM_CXICON); int cyIcon = GetSystemMetrics(SM_CYICON); CRect rect; GetClientRect(&rect); int x = (rect.Width() - cxIcon + 1) / 2; int y = (rect.Height() - cyIcon + 1) / 2; // 绘制图标 dc.DrawIcon(x, y, m_hIcon); } else { // // 给窗口加入�背景 // CPaintDC dc(this); CRect rc; GetClientRect(&rc); CDC dcMem; dcMem.CreateCompatibleDC(&dc); CBitmap bmpBackground; bmpBackground.LoadBitmap(IDB_BITMAP1); BITMAP bitmap; bmpBackground.GetBitmap(&bitmap); CBitmap* pbmpPri = dcMem.SelectObject(&bmpBackground); dc.StretchBlt(0,0,rc.Width(), rc.Height(), &dcMem,0,0,bitmap.bmWidth, bitmap.bmHeight, SRCCOPY); } }
