下载本文示例代码
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 < 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 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();

	/////////////////////////////////////////////////////////////////////////

}

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;

}
