cpropertysheet:使用CPropertySheet类的方法

来源: 发布时间:星期四, 2009年2月12日 浏览:160次 评论:0


为了最大限度发挥属性页效用首先让我们先从 CPropertySheet 继承个新类取名为 CMyPropSheet.
接着便可以进行下面各种操作:

、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 );

2、移动属性页按钮
首先要获取按钮句柄然后就可以象对待窗体样处理它们了. 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;

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;
nSpacing = 6; // space between two buttons...

for( i =0; i < (ids)/(); i)
{
GetDlgItem (ids [i])->GetWindowRect (rectBtn);

ScreenToClient (&rectBtn);
btnWidth = rectBtn.Width;
rectBtn.left = rectBtn.left + (btnWidth + nSpacing)* 2;
rectBtn.right = rectBtn.right + (btnWidth + nSpacing)* 2; [Page]

GetDlgItem (ids [i])->MoveWindow(rectBtn);
}


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大小.BOOL CMyPropSheet::OnInitDialog
{
BOOL bResult = CPropertySheet::OnInitDialog;


ids = { IDOK, IDCANCEL, ID_APPLY_NOW };



CRect rectWnd;
CRect rectBtn;

GetWindowRect (rectWnd);
GetDlgItem (IDOK)->GetWindowRect (rectBtn);

btnWidth = rectBtn.Width;
btnHeight = rectBtn.Height;
btnOff = rectWnd.bottom - rectBtn.bottom;
btnLeft = rectWnd.right - rectWnd.left;

rectWnd.bottom = rectBtn.top;
rectWnd.right = rectWnd.right + btnWidth + btnOff;
MoveWindow(rectWnd);

rectBtn.left = btnLeft;
rectBtn.right = btnLeft + btnWidth;

for ( i = 0; i < (ids) / (); i)
{
rectBtn.top = (i + 1) * btnOff + btnHeight * i;
rectBtn.bottom = rectBtn.top + btnHeight;
GetDlgItem (ids [i])->MoveWindow (rectBtn);
} [Page]

bResult;
}


3、改变属性页上标签文字
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);

4、改变属性页标签文字字体属性
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);

5、在属性页标签上显示位图
可以用 CImageList 建立图像. 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 ( i = 0; i < NUMBER_OF_TABS; i)
{
item.iImage = i;


pTabCtrl->SetItem (i, &item );
}

bResult;
}


6、在属性页左下角显示位图
如下代码所示: void CMyPropSheet::OnPa
{
CPaDC dc(this); // device context for paing

nOff = 6;
// load IDB_BITMAP1 from our resources [Page]
CBitmap bmp;
(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 pa
CDC dcMemory;
dcMemory.CreateCompatibleDC (&dc);

// Select the bitmap o the in-memory DC
CBitmap* pOldBitmap = dcMemory.SelectObject (&bmp);

// Find a bottom-left po for the bitmap in the client area
CRect rect;
GetClientRect (&rect);
nX = rect.left + nOff;
nY = rect.top + (rect.Height - bmpInfo.bmHeight) - nOff;

// Copy the bits from the in-memory DC o the _disibledevent=> 7、在属性页右下角显示
3D文字Logo
代码如下:void CMyPropSheet::OnPa
{
/////////////////////////////////////////////////////////////////////////
//
TAB按钮旁边显示

3D文字提示,jingzhou xu
C m_LogoName = “
属性页”;
// (m_LogoName \"\")
// ;

GetWindowRect(rect);
ScreenToClient(rect);

LOGFONT logFont;
ZeroMemory((void*)&logFont,(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; [Page]
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); [Page]

TEXTMETRIC tm;
pDC->GetTextMetrics(&tm);
CFont* oldFont = pDC->SelectObject(&m_LogoFont);
CSize sz = pDC->GetTextExtent(sLogoString, sLogoString.GetLength);


//
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);
//
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);
[Page]
//
释放资源
pDC->SelectObject(oldFont);
pDC->SetTextColor(oldColor);
m_LogoFont.DeleteObject;
/////////////////////////////////////////////////////////////////////////
}

8、在属性页中动态加入其它Control控件
下面演示如何在左下角加入EditControl控件:
MyPropSheet.h
:public:
CEdit m_edit;

MyPropSheet.cpp
:BOOL CMyPropSheet::OnInitDialog
{
BOOL bResult = CPropertySheet::OnInitDialog ;


CRect rect;

nHeight = 24;
nWidth = 120;
nOff = 6;

GetClientRect (&rect);

// Find a bottom-left po for the edit control in the client area
nX = rect.left + nOff;
nY = rect.top + (rect.Height - nHeight) - nOff;



// 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_
MSDN say:
BOOL CMySheet::OnInitDialog
{
CPropertySheet::OnInitDialog;

RECT rc;

// resize the sheet
GetWindowRect (&rc);
ScreenToClient (&rc);
rc.right 50;
rc.bottom 50;
MoveWindow (&rc);

// resize the CTabCtrl
CTabCtrl* pTab = GetTabControl ;
ASSERT (pTab);
pTab->GetWindowRect (&rc);
ScreenToClient (&rc);
rc.right 50;
rc.bottom 50;
pTab->MoveWindow (&rc);

// resize the page
CPropertyPage* pPage = GetActivePage ;
ASSERT (pPage);
// store page size in m_PageRect
pPage->GetWindowRect (&m_PageRect);
ScreenToClient (&m_PageRect);
m_PageRect.right 50;
m_PageRect.bottom 50;
pPage->MoveWindow (&m_PageRect);

// move the OK, Cancel, and Apply buttons
CWnd* pWnd = GetDlgItem(IDOK);
pWnd->GetWindowRect(&rc);
rc.bottom 50;
rc.top 50;
ScreenToClient(&rc);
pWnd->MoveWindow(&rc);

pWnd = GetDlgItem(IDCANCEL);
pWnd->GetWindowRect(&rc);
rc.bottom 50;
rc.top 50;
ScreenToClient(&rc);
pWnd->MoveWindow(&rc);

pWnd = GetDlgItem(ID_APPLY_NOW);
pWnd->GetWindowRect(&rc);
rc.bottom 50;
rc.top 50;
ScreenToClient(&rc);
pWnd->MoveWindow(&rc);

CenterWindow;

TRUE;
}
