[MFC] CMFCRibbonColorButton how to get the color

Dear All,

I would like to access to the user selected color in a color pallete added to a Ribbon bar. By now I have created the Ribbon button, added it to the panel, added an event to handle the "click" on that button and overwritten the OnEraseBkgnd(CDC* pDC) in my view class.

I present some code snippets. I at this stage I am not able to access to the background color selected by the suer.

In the view class:

        ..
         //background color message:
 ON_COMMAND(ID_RIBBON_RIBBON12,&CHowdenSelectView::OnBackgroundColor)
         ...

         BOOL CHowdenSelectView::OnEraseBkgnd(CDC* pDC)
         {
 CBrush backBrush(RGB(m_rValue,128,128));
 m_rValue+=10;
 if(m_rValue>255)
 {
 m_rValue=0;
 }

 CBrush *pOldBrush = pDC->SelectObject(&backBrush);

 CRect rect;
 pDC->GetClipBox(&rect);

 pDC->PatBlt(rect.left,rect.top,rect.Width(),rect.Height(),PATCOPY);
 pDC->SelectObject(pOldBrush);

 return true;}

         void CHowdenSelectView::OnBackgroundColor()
         {

         this->OnEraseBkgnd(this->GetDC());
         }
         ...

In the mainframe:

    //view tab
     pCategory = m_wndRibbonBar.AddCategory(_T("View"),IDB_FILESMALL, IDB_FILELARGE); 
     pPanel = pCategory->AddPanel(_T("Visual Style"));
     CMFCRibbonColorButton *pColorButton = new CMFCRibbonColorButton (ID_RIBBON_RIBBON12,_T      ("Background color"),TRUE,1, -1);//by putting -1 u specify that there is no color
 pColorButton->SetDefaultCommand(FALSE);
 pColorButton->EnableAutomaticButton(_T("&Automatic"),RGB(0,0,0));   //select default: minute: 13:32.
 pColorButton->EnableOtherButton(_T("&More Colors..."),_T("More colors tooltip"));
 pPanel->Add(pColorButton);

Could anyone suggest me how to access to the currently selected color in the OnBackgroundColor method? Many thanks and best regards!
