Skinning property sheet / OnCtlColor

After upgrading from 10.3.1 to 10.4 (as well as 10.4.1) some controls (labels, checkbox) are not skinned correctly anymore.

The problem is that OnCtlColor of the property page is overloaded and returns a white brush, because without skinning the background should be white.

Is this a bug or is the changed behaviour intended?



To reproduce this:

In SkinPropertyPageControls.h add:


//{{AFX_MSG(CSkinPropertyPageControls)
afx_msg HBRUSH OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor);
virtual BOOL OnInitDialog();
//}}AFX_MSG

In SkinPropertyPageControls.cpp add:

//{{AFX_MSG_MAP(CSkinPropertyPageControls)
ON_WM_CTLCOLOR()
//}}AFX_MSG_MAP

HBRUSH CSkinPropertyPageControls::OnCtlColor (CDC *pDC, CWnd *pWnd, UINT nCtlColor)
{
    pDC->SetBkMode (TRANSPARENT);
    return ::GetSysColorBrush (COLOR_WINDOW);
}
