Re: Weird problem for BS_OWNERDRAW BN_CLICKED

After two days of working I finally get a working solution !!! :)

Here is the trick :

-----------------------------------------------------------------------------------
BEGIN_MESSAGE_MAP(CBitmapCheckBox, CButton)
   ON_WM_LBUTTONUP()
   ON_WM_LBUTTONDOWN()
   ON_CONTROL_REFLECT(BN_CLICKED, &CBitmapCheckBox::OnBnClicked)
END_MESSAGE_MAP()

void CBitmapCheckBox::OnBnClicked()
{
    // Do nothing !
    // Message will be send to parent in Mouse Up Button event
}

void CBitmapCheckBox::OnLButtonUp(UINT nFlags, CPoint point)
{
   CButton::OnLButtonUp(nFlags, point);

   // Get windows rect
   CRect rectButtton;
   GetClientRect(&rectButtton);

   // Verify that user has release the mouse
   // button above the control
   if ( rectButtton.PtInRect(point) )
   {
       // Change check state
       if (m_bCheckState == BST_CHECKED)
       {
             m_bCheckState = BST_UNCHECKED;
       }
       else if (m_bCheckState == BST_UNCHECKED)
       {
             m_bCheckState = BST_CHECKED;
       }
      
       GetParent()->SendMessage(WM_COMMAND, GetDlgCtrlID(), BN_CLICKED);
   }

   // Refresh display
   Invalidate();
}

void CBitmapCheckBox::OnLButtonDown(UINT nFlags, CPoint point)
{
    // Set button state
    m_iState = BTN_PUSHED_STATE;

    // Refresh display
    Invalidate();

    CButton::OnLButtonDown(nFlags, point);
}

LRESULT CBitmapCheckBox::WindowProc(UINT message, WPARAM wParam, LPARAM
lParam)
{
   // Owner drawn buttons (derived class) double click does only a
   // WM_LBUTTONDOWN ! Here is the solution :
   if (message == WM_LBUTTONDBLCLK)
   {
       message = WM_LBUTTONDOWN;
   }

   return CButton::WindowProc(message, wParam, lParam);
}
-----------------------------------------------------------------------------------

Thank anyway for your help :)
