MFC VC++: CMFCButton::SetFaceColor does not change background(face) color

Question

I have a CMFCButton on a CFormView. I want it to have a particular background color. I came across CMFCButton::SetFaceColor which I thought would do that. But unfortunately it didnt work. May be I'm misunderstanding the "Face" terminology here. Is that the case?

Here's my code:

m_btnCopy.SetFaceColor(RGB(255,0,0),true);
m_btnCopy.SetTextColor(RGB(0,0,255));

and output:

Answer 1

This setting is quite archaic and is ignored by modern theme engines. Most likely your application was generated by Visual Studio wizard and contains something like:

CMFCVisualManager::SetDefaultManager(RUNTIME_CLASS(CMFCVisualManagerWindows));

You can try to remove this line to disable custom MFC themes but the button will not look good anyway, after SetFaceColor it will be drawn in classic theme.

Answer 2

almost same method but slightly better look.

  m_btnCopy.EnableWindowsTheming(FALSE);
  m_btnCopy.m_nFlatStyle = CMFCButton::BUTTONSTYLE_FLAT;
  m_btnCopy.m_bTransparent = false;
  m_btnCopy.SetFaceColor(RGB(255,0,0),true);
  m_btnCopy.SetTextColor(RGB(0,0,255));

Other people suggest to use m_bDontUseWinXPTheme = TRUE. It works due to the following code in afxbutton.cpp:

void CMFCButton::DrawBorder(CDC* pDC, CRect& rectClient, UINT uiState)
{
   <snip>

   // Draw 3d border:
   if (m_nFlatStyle != BUTTONSTYLE_NOBORDERS)
   {
       if (m_bWinXPTheme && !m_bDontUseWinXPTheme && CMFCVisualManager::GetInstance()->DrawPushButtonWinXP(pDC, rectClient, this, uiState))

The 'DrawPushButtonWinXP' isn't invoked anymore when m_bDontUseWinXPTheme is set. You get though an ugly old style button.

试试这些代码。

mCMFCBtn.m_bGrayDisabled = FALSE;

mCMFCBtn.m_bDontUseWinXPTheme = TRUE;

mCMFCBtn.m_nFlatStyle = CMFCButton::BUTTONSTYLE_FLAT;

mCMFCBtn.SetFaceColor(RGB(255, 0, 0), TRUE);

mCMFCBtn.SetTextColor(RGB(0, 0, 0));
