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. 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 < sizeof(ids)/sizeof(int); i++) { GetDlgItem (ids [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 < sizeof (ids) / sizeof (int); i++) { rectBtn.top = (i + 1) * btnOffset + btnHeight * i; rectBtn.bottom = rectBtn.top + btnHeight; GetDlgItem (ids [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 < NUMBER_OF_TABS; i++) { item.iImage = i; pTabCtrl->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 we''re 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 the client area int nX = rect.left + nOffset; int nY = rect.top + (rect.Height() - nHeight) - nOffset; // finally create the edit control m_Edit.CreateEx (WS_EX_CLIENTEDGE, _T("EDIT"), NULL, WS_CHILD | WS_VISIBLE | WS_TABSTOP | WS_BORDER, nX, nY, nWidth, nHeight, m_hWnd, 0, 0 ); return bResult;}
