Displaying the Note Property

To display the Note property, change the drawing behavior in the OnDraw function in CIRCCTL.CPP. The Note property is drawn in the upper-left corner of the control's bounding rectangle, using the stock Font and ForeColor properties.

To change the OnDraw function to display the Note property

• Change or add the following lines in the OnDraw function in CIRCCTL.CPP:

     // Draw the caption and note using the stock Font and ForeColor properties
  ...
     pdc->SetTextAlign(TA_LEFT | TA_TOP);
     pdc->ExtTextOut(rc.left, rc.top,
         ETO_CLIPPED, rc, m_note, m_note.GetLength(), NULL);
  

  as shown in the following example:

  void CCircCtrl::OnDraw(
              CDC* pdc, const CRect& rcBounds, const CRect& rcInvalid)
  {
      CBrush* pOldBrush;
      CBrush bkBrush(TranslateColor(GetBackColor()));
      CPen* pOldPen;
      CRect rc = rcBounds;
      CFont* pOldFont;
      TEXTMETRIC tm;
      const CString& strCaption = InternalGetText();
  
      // Set the ForeColor property color and transparent background mode into the device context
      pdc->SetTextColor(TranslateColor(GetForeColor()));
      pdc->SetBkMode(TRANSPARENT);
  
      // Paint the background using the BackColor property
      pdc->FillRect(rcBounds, &bkBrush);
  
      // Draw the ellipse using the BackColor property and a black pen
      GetDrawRect(&rc);
      pOldBrush = pdc->SelectObject(&bkBrush);
      pOldPen = (CPen*)pdc->SelectStockObject(BLACK_PEN);
      pdc->Ellipse(rc);
  
     // Draw the caption and note using the stock Font and ForeColor properties
      pOldFont = SelectStockFont(pdc);
      pdc->GetTextMetrics(&tm);
      pdc->SetTextAlign(TA_CENTER | TA_TOP);
      pdc->ExtTextOut((rc.left + rc.right) / 2, (rc.top + rc.bottom - tm.tmHeight) / 2,
          ETO_CLIPPED, rc, strCaption, strCaption.GetLength(), NULL);
     pdc->SetTextAlign(TA_LEFT | TA_TOP);
     pdc->ExtTextOut(rc.left, rc.top,
         ETO_CLIPPED, rc, m_note, m_note.GetLength(), NULL);
      pdc->SelectObject(pOldFont);
  
      pdc->SelectObject(pOldPen);
      pdc->SelectObject(pOldBrush);
  }
