深入浅出CPropertySheet.doc

深入浅出 CPropertySheet为了最大限度的发挥属性页的效用，首先让我们先从 CPropertySheet 继承一个新类，取名为 CMyPropSheet.接着便可以进行下面的各种操作:一、隐藏属性页默认按钮 隐藏掉Apply应用按钮: propsheet.m_psh.dwFlags |= PSH_NOAPPLYNOW;或隐藏掉Cancel取消按钮:CWnd *pWnd = GetDlgItem( IDCANCEL );pWnd-ShowWindow( FALSE );二、移动属性页按钮首先，要获取按钮的句柄，然后就可以象对待窗体一样处理它们了. 下面代码先隐藏掉Apply和Help铵钮，再把OK和Cancel按移动到右侧。 BOOL CMyPropSheet:OnInitDialog () BOOL bResult = CPropertySheet:OnInitDialog(); int ids = IDOK, IDCANCEL;/, ID_APPLY_NOW, IDHELP ; / Hide Apply and Help buttons CWnd *pWnd = GetDlgItem (ID_APPLY_NOW); pWnd-ShowWindow (FALSE); pWnd = GetDlgItem (IDHELP); pWnd-ShowWindow (FALSE); CRect rectBtn; int nSpacing = 6; / space between two buttons. for( int i =0; i GetWindowRect (rectBtn); ScreenToClient (&rectBtn); int btnWidth = rectBtn.Width(); rectBtn.left = rectBtn.left + (btnWidth + nSpacing)* 2; rectBtn.right = rectBtn.right + (btnWidth + nSpacing)* 2; GetDlgItem (ids i)-MoveWindow(rectBtn); return bResult;下面代码移动所有按钮到右侧，并且重新置属性页为合适的大小.BOOL CMyPropSheet:OnInitDialog () BOOL bResult = CPropertySheet:OnInitDialog(); int ids = IDOK, IDCANCEL, ID_APPLY_NOW ; CRect rectWnd; CRect rectBtn; GetWindowRect (rectWnd); GetDlgItem (IDOK)-GetWindowRect (rectBtn); int btnWidth = rectBtn.Width(); int btnHeight = rectBtn.Height(); int btnOffset = rectWnd.bottom - rectBtn.bottom; int btnLeft = rectWnd.right - rectWnd.left; rectWnd.bottom = rectBtn.top; rectWnd.right = rectWnd.right + btnWidth + btnOffset; MoveWindow(rectWnd); rectBtn.left = btnLeft; rectBtn.right = btnLeft + btnWidth; for (int i = 0; i MoveWindow (rectBtn); return bResult;三、改变属性页上的标签文字首先修改TC_ITEM结构，然后用 SetItem 来修改标签文字，如下代码:TC_ITEM item;item.mask = TCIF_TEXT;item.pszText = New Label;/Change the label of the first tab (0 is the index of the first tab).GetTabControl ()-SetItem (0, &item);四、改变属性页标签文字的字体属性代码如下m_NewFont.CreateFont (14, 0, 0, 0, 800, TRUE, 0, 0, 1, 0, 0, 0, 0, _T(Arial) ); GetTabControl()-SetFont (&m_NewFont);五、在属性页标签上显示位图 可以用 CImageList 建立图像. 用 SetItem 来设置，如下代码所示:BOOL CMyPropSheet:OnInitDialog () BOOL bResult = CPropertySheet:OnInitDialog(); m_imageList.Create (IDB_MYIMAGES, 13, 1, RGB(255,255,255); CTabCtrl *pTabCtrl = GetTabControl (); pTabCtrl-SetImageList (&m_imageList); TC_ITEM item; item.mask = TCIF_IMAGE; for (int i = 0; i SetItem (i, &item ); return bResult;六、在属性页左下角显示位图如下代码所示： void CMyPropSheet:OnPaint () CPaintDC dc(this); / device context for painting int nOffset = 6; / load IDB_BITMAP1 from our resources CBitmap bmp; if (bmp.LoadBitmap (IDB_BITMAP1) / Get the size of the bitmap BITMAP bmpInfo; bmp.GetBitmap (&bmpInfo); / Create an in-memory DC compatible with the / display DC were using to paint CDC dcMemory; dcMemory.CreateCompatibleDC (&dc); / Select the bitmap into the in-memory DC CBitmap* pOldBitmap = dcMemory.SelectObject (&bmp); / Find a bottom-left point for the bitmap in the client area CRect rect; GetClientRect (&rect); int nX = rect.left + nOffset; int nY = rect.top + (rect.Height () - bmpInfo.bmHeight) - nOffset; / Copy the bits from the in-memory DC into the on- / screen DC to actually do the painting. Use the centerpoint / we computed for the target offset. dc.BitBlt (nX, nY, bmpInfo.bmWidth, bmpInfo.bmHeight, &dcMemory, 0, 0, SRCCOPY); dcMemory.SelectObject (pOldBitmap); / Do not call CPropertySheet:OnPaint() for painting messages七、在属性页右下角显示3D文字Logo代码如下:void CMyPropSheet:OnPaint () /在TAB按钮旁边显示3D文字提示,jingzhou xuCstring m_LogoName = “属性页”;/if(m_LogoName = )/return;GetWindowRect(rect);ScreenToClient(rect);LOGFONT logFont;ZeroMemory(void*)&logFont,sizeof(logFont);strcpy(logFont.lfFaceName,宋体);logFont.lfHeight = -12;logFont.lfWeight = 400;logFont.lfCharSet = GB2312_CHARSET;logFont.lfOutPrecision = 3;logFont.lfClipPrecision = 2; logFont.lfQuality = 1;logFont.lfPitchAndFamily = 2;m_font.CreateFontIndirect(&logFont);SetFont(&m_font);CFont*pOldFont = pDC-SelectObject(&m_font);rect.left += 6;rect.right -= 6;rect.bottom -= 1;rect.top = rect.bottom - ITEMBUTTON_HEIGHT + 1;CFont m_LogoFont;CString sLogoString;m_LogoFont.CreateFont(rect.Height()*4/5, 0, 0, 0, FW_BOLD, 1, FALSE, FALSE,DEFAULT_CHARSET, OUT_DEFAULT_PRECIS, CLIP_DEFAULT_PRECIS, DEFAULT_QUALITY,FIXED_PITCH | FF_ROMAN, 楷体_GB2312);sLogoString = m_LogoName;RECT m_rDataBox;CopyRect(&m_rDataBox,&rect);TEXTMETRIC tm;pDC-GetTextMetrics(&tm);CFont* oldFont = pDC-SelectObject(&m_LogoFont);CSize sz = pDC-GetTextExtent(sLogoString, sLogoString.GetLength();/用GetTextExtent来计算字体logo大小，依靠于设备环境，使用logo位于右下角m_rDataBox.left = m_rDataBox.right - sz.cx - tm.tmAveCharWidth/2;m_rDataBox.top = m_rDataBox.bottom - sz.cy - tm.tmHeight/5;pDC-SetBkMode(TRANSPARENT);/用3D字体显示，先黑后白，最后再用默认色COLORREF oldColor = pDC-SetTextColor(GetSysColor(COLOR_3DDKSHADOW);pDC-DrawText(sLogoString, sLogoString.GetLength(), &m_rDataBox, DT_VCENTER | DT_SINGLELINE | DT_CENTER);m_rDataBox.left -= tm.tmAveCharWidth;pDC-SetTextColor(GetSysColor(COLOR_3DHILIGHT);pDC-DrawText(sLogoString, sLogoString.GetLength(), &m_rDataBox, DT_VCENTER | DT_SINGLELINE | DT_CENTER);m_rDataBox.left += 3*tm.tmAveCharWidth/5;pDC-SetTextColor(RGB(0,0,255);pDC-DrawText(sLogoString, sLogoString.GetLength(), &m_rDataBox, DT_VCENTER | DT_SINGLELINE | DT_CENTER);/释放资源pDC-SelectObject(oldFont);pDC-SetTextColor(oldColor); m_LogoFont.DeleteObject();/八、在属性页中动态加入其它控件下面演示如何在左下角加入一Edit控件:MyPropSheet.h中:public: CEdit m_edit;MyPropSheet.cpp中:BOOL CMyPropSheet:OnInitDialog () BOOL bResult = CPropertySheet:OnInitDialog (); CRect rect; int nHeight = 24; int nWidth = 120; int nOffset = 6; GetClientRect (&rect); / Find a bottom-left point for the edit control in th
