透明的CheckBox的代码

透明的CheckBox，基类是CButton...
主要代码如下
OnPaint()
{
 CPaintDC dc(this); // device context for painting
   
    // TODO: Add your message handler code here
   
    CRect rect;
    GetClientRect(&rect);

    CRect BoxRect;
    BoxRect=rect;
    BoxRect.right =BoxRect.left +15;
    dc.DrawFrameControl(BoxRect,DFC_BUTTON,DFCS_BUTTONCHECK|GetCheck()?DFCS_CHECKED :0);

    CFont   myFont; 
    myFont.CreatePointFont (120,_T("宋体"));
    CFont   *pOldFont=(CFont   *)dc.SelectObject   (&myFont); 
    dc.SetBkMode(TRANSPARENT);  
   
    CString StrWndText;
    GetWindowText(StrWndText);

    rect.OffsetRect (20,0);
    dc.DrawText(StrWndText,   rect,   DT_LEFT|DT_VCENTER|DT_SINGLELINE);  
    dc.SelectObject   (pOldFont); 
    myFont.DeleteObject   (); 
    // Do not call CButton::OnPaint() for painting messages
}
