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:
l       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 );
 
l       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ApplyHelp铵钮,再把OKCancel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;
}
l       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);
l       改变属性页标签文字的字体属性
如下代码:
    m_NewFont.CreateFont (14, 0,
0
, 0, 800, TRUE, 0, 0,1,
0, 0, 0, 0, _T("Arial") );
    GetTabControl()->SetFont (&m_NewFont);
l       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;
}
l       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
}
l       在属性页右下角显示3D文字Logo
如下代码:
void CMyPropSheet::OnPaint ()
{
    /////////////////////////////////////////////////////////////////////////
         //在TAB按钮旁边显示3D文字提示,jingzhou xu
         Cstring 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();
         /////////////////////////////////////////////////////////////////////////
}
 
l       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:
In MyPropSheet.h:
public:
    CEdit m_edit;
In MyPropSheet.cpp:
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;
}
