Upon color change, i listen to WM_CTLCOLORSTATIC and act accordingly:
LRESULT ProcessWindowMessage(_In_ HWND hWnd, _In_ UINT uMsg, _In_ WPARAM wParam, _In_ LPARAM lParam)
{
switch (uMsg)
{
case WM_CTLCOLORSTATIC:
LRESULT lBrush = ::DefWindowProc(hWnd, uMsg, wParam, lParam); // get default brush used so far
::SetBkMode((HDC)wParam, TRANSPARENT);
::SetTextColor((HDC)wParam, RGB(m_color.red, m_color.green, m_color.blue));
return lBrush;
}
}
This works well with regular static-texts: labels and so on, but has no effect on regular radio buttons.
During my debugging attempts, I've tried listening to:
I'm subclassing to another window not generated / created by me, but constructed by my process.
@igal k said SetWindowTheme does not work. Since the comment is not enough for the sample code. I post it as an answer.
First the result.
Code:
OnInitDialog:
::SetWindowTheme(GetDlgItem(IDC_RADIO1)->GetSafeHwnd(), L"wstr", L"wstr");
HBRUSH CMFCApplication1Dlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
// Call the base class implementation first! Otherwise, it may
// undo what we're trying to accomplish here.
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
// Are we painting the IDC_MYSTATIC control? We can use
// CWnd::GetDlgCtrlID() to perform the most efficient test.
if (pWnd->GetDlgCtrlID() == IDC_RADIO1)
{
// Set the text color to red
pDC->SetTextColor(RGB(255, 0, 0));
// Set the background mode for text to transparent
// so background will show thru.
pDC->SetBkMode(TRANSPARENT);
// Return handle to our CBrush object
hbr = m_brush;
}
return hbr;
}
