如何让dialog上的static控件底色透明？OnCtlColor这个函数怎麽用啊？

Question

我把dialog涂了颜色，但是static控件的背景没法去掉。OnCtlColor这个函数不会用。

Answer 1

HBRUSH CLogToolDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) 
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

// set edit properities
    if(pWnd->GetDlgCtrlID() == IDC_EDIT_LOG)
    {
        static HBRUSH hbrEdit = ::CreateSolidBrush(RGB(255, 255, 255));
        pDC->SetBkColor(RGB(255, 255, 255));
        pDC->SetTextColor(RGB(0, 0, 255));
        return hbrEdit;
    }

return hbr;
} // end of OnCtlColor()

Answer 2

The WM_CTLCOLOR message has been replaced by more specific notifications in 32-bit versions of Windows. These replacements include the following:
WM_CTLCOLORBTN 
WM_CTLCOLOREDIT 
WM_CTLCOLORDLG 
WM_CTLCOLORLISTBOX 
WM_CTLCOLORSCROLLBAR 
WM_CTLCOLORSTATIC 要改Static的话，建议用WM_CTLCOLORSTATIC，或者自己继承一个Static，然后写OnPaint

HBRUSH CTest6Dlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) 
{ HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
switch(nCtlColor)
{
case CTLCOLOR_STATIC:
if(pWnd->GetDlgCtrlID() == IDC_STATIC2)
{
if(GetFocus() == (CStatic*)GetDlgItem(IDC_STATIC2))
{
static HBRUSH hbrEdit = ::CreateSolidBrush( RGB(255, 255, 255) );
pDC->SetBkColor(TRANSPARENT);
pDC->SetTextColor( RGB(255, 0, 0) );
return hbrEdit;
}
}
} // TODO: Return a different brush if the default is not desired
return hbr;
}
