VC++界面美化

VC++界面美化VC开发程序单调的界面相信大家都是深有感触，提到界面美化编程，人们都会说做界面不要用VC写，太难了。

一句俗语：难者不会，会者不难。

VC的美化界面编程并没有人们想像的那么难。

这篇文章是我写的一个用户登录界面，但界面被我美化了，下面将一步一步的来讲解它的美化界面的实现步骤。

相信有了这篇文章，你的VC界面从此也能绚丽多彩。

实现步骤：第一步：美化界面的非客户区(重绘标题栏和界面边框)。

关键代码如下：// 函数名：DrawTitleBar// 功能描述：绘制标题栏、边框颜色，绘制标题内容、图标和按钮// 输入参数：pDC：设备指针// 输出参数：void// 创建日期：2006-2-20// 修改日期：2006-2-20// 作者：joinclear// 附加说明：无void CTitleBarColorDlg::DrawTitleBar(CDC *pDC){if (m_hWnd){CBrush Brush(RGB(187,200,143));CBrush* pOldBrush = pDC->SelectObject(&Brush); CRect rtWnd, rtTitle, rtButtons;GetWindowRect(&rtWnd);//取得标题栏的位置//SM_CXFRAME 窗口边框的边缘宽度//SM_CYFRAME 窗口边框的边缘高度//SM_CXSIZE 窗口标题栏宽度//SM_CYSIZE 窗口标题栏高度rtTitle.left = GetSystemMetrics(SM_CXFRAME);rtTitle.top = GetSystemMetrics(SM_CYFRAME);rtTitle.right = rtWnd.right - rtWnd.left - GetSystemMetrics(SM_CXFRAME);rtTitle.bottom = rtTitle.top + GetSystemMetrics(SM_CYSIZE);CPoint point;//填充顶部框架point.x = rtWnd.Width(); point.y = GetSystemMetrics(SM_CYSIZE) +GetSystemMetrics(SM_CYFRAME) + 0;pDC->PatBlt(0, 0, point.x, point.y, PATCOPY); //填充左侧框架point.x = GetSystemMetrics(SM_CXFRAME) -1;point.y = rtWnd.Height()- 1;pDC->PatBlt(0, 0, point.x, point.y, PATCOPY); //填充底部框架point.x = rtWnd.Width();point.y = GetSystemMetrics(SM_CYFRAME);pDC->PatBlt(0, rtWnd.Height()-point.y, point.x, point.y, PATCOPY);//填充右侧框架point.x = GetSystemMetrics(SM_CXFRAME);point.y = rtWnd.Height();pDC->PatBlt(rtWnd.Width()-point.x, 0, point.x, point.y, PATCOPY);//重画标题栏图标m_rtIcon.left = rtTitle.left ;m_rtIcon.top = rtTitle.top;m_rtIcon.right = m_rtIcon.left + 16;m_rtIcon.bottom = m_rtIcon.top + 15;::DrawIconEx(pDC->m_hDC, m_rtIcon.left,m_rtIcon.top, AfxGetApp()->LoadIcon(IDR_MAINFRAME),m_rtIcon.Width(), m_rtIcon.Height(), 0, NULL, DI_NORMAL);m_rtIcon.OffsetRect(rtWnd.TopLeft());CBitmap* pBitmap = new CBitmap;CBitmap* pOldBitmap;CDC* pDisplayMemDC=new CDC;pDisplayMemDC->CreateCompatibleDC(pDC);//重画关闭buttonrtButtons.left = rtTitle.right - 16;rtButtons.top = rtTitle.top - 1;rtButtons.right = rtButtons.left + 16;rtButtons.bottom = rtButtons.top + 15;pBitmap->LoadBitmap(IDB_EXIT_FOCUS);pOldBitmap=(CBitmap*)pDisplayMemDC->SelectObject(p Bitmap);pDC->BitBlt(rtButtons.left, rtButtons.top, rtButtons.Width(), rtButtons.Height(), pDisplayMemDC, 0,0, SRCCOPY);pDisplayMemDC->SelectObject(pOldBitmap);m_rtButtExit = rtButtons;m_rtButtExit.OffsetRect(rtWnd.TopLeft());pBitmap->DeleteObject();//重画最大化/恢复buttonrtButtons.right = rtButtons.left - 3;rtButtons.left = rtButtons.right - 16;if (IsZoomed())pBitmap->LoadBitmap(IDB_RESTORE_NORMAL);elsepBitmap->LoadBitmap(IDB_MAX_NORMAL);pOldBitmap=(CBitmap*)pDisplayMemDC->SelectObject(p Bitmap);pDC->BitBlt(rtButtons.left, rtButtons.top, rtButtons.Width(), rtButtons.Height(), pDisplayMemDC, 0, 0, SRCCOPY);pDisplayMemDC->SelectObject(pOldBitmap);m_rtButtMax = rtButtons;m_rtButtMax.OffsetRect(rtWnd.TopLeft());pBitmap->DeleteObject();//重画最小化buttonrtButtons.right = rtButtons.left - 3;rtButtons.left = rtButtons.right - 16;pBitmap->LoadBitmap(IDB_MIN_NORMAL);pOldBitmap=(CBitmap*)pDisplayMemDC->SelectObject(p Bitmap);pDC->BitBlt(rtButtons.left, rtButtons.top, rtButtons.Width(), rtButtons.Height(), pDisplayMemDC, 0, 0, SRCCOPY);pDisplayMemDC->SelectObject(pOldBitmap);m_rtButtMin = rtButtons;m_rtButtMin.OffsetRect(rtWnd.TopLeft());pBitmap->DeleteObject();//重画captionint nOldMode = pDC->SetBkMode(TRANSPARENT);COLORREF clOldText=pDC->SetTextColor(RGB(255, 255, 255));CFont m_captionFont;m_captionFont.CreateFont(18, // 字体的高度0, // 字体的宽度0, // 字体显示的角度0, // 字体的角度FW_BOLD, // 字体的磅数FALSE, // 斜体字体FALSE, // 带下划线的字体0, // 带删除线的字体ANSI_CHARSET, // 所需的字符集OUT_DEFAULT_PRECIS, // 输出的精度CLIP_DEFAULT_PRECIS, // 裁减的精度DEFAULT_QUALITY, // 逻辑字体与输出设备的实际字体之间的精度DEFAULT_PITCH | FF_SWISS, // 字体间距和字体集 _T("Arial")); // 字体名称CFont* pOldFont = NULL;pOldFont = pDC->SelectObject(&m_captionFont);rtTitle.left += m_rtIcon.Width ()+3;rtTitle.top = rtTitle.top;rtTitle.bottom = rtTitle.top + 30;CString m_strTitle;GetWindowText(m_strTitle);pDC->DrawText(m_strTitle, &rtTitle, DT_LEFT); pDC->SetBkMode(nOldMode);pDC->SetTextColor(clOldText);ReleaseDC(pDisplayMemDC);delete pDisplayMemDC;delete pBitmap;}}还有在非客户区绘制鼠标的消息。
