COleIPFrameWndEx Class

  • Artikkeli

The COleIPFrameWndEx class implements an OLE container that supports MFC. You must derive the in-place frame window class for your application from the COleIPFrameWndEx class, instead of deriving it from the COleIPFrameWndclass. For more detail see the source code located in the VC\atlmfc\src\mfc folder of your Visual Studio installation.

Example

The following example demonstrates how to subclass an instance of the COleIPFrameWndEx class and over ride its methods. The example shows how to over ride the OnDestory method, the RepositionFrame method, the RecalcLayout method, and the CalcWindowRect method. This code snippet is part of the Word Pad sample.

void CInPlaceFrame::OnDestroy()
{
   m_wndToolBar.DestroyWindow();
   m_wndFormatBar.DestroyWindow();
   COleIPFrameWndEx::OnDestroy();
}

void CInPlaceFrame::RepositionFrame(LPCRECT lpPosRect, LPCRECT lpClipRect)
{
   CRect rectNew = lpPosRect;
   rectNew.left -= HORZ_TEXTOFFSET;
   rectNew.top -= VERT_TEXTOFFSET;
   m_wndResizeBar.BringWindowToTop();
   COleIPFrameWndEx::RepositionFrame(&rectNew, lpClipRect);
   CWnd *pWnd = GetActiveView();
   if (pWnd != NULL)
      pWnd->BringWindowToTop();
   m_wndRulerBar.BringWindowToTop();
}

void CInPlaceFrame::RecalcLayout(BOOL bNotify)
{
   if (m_wndResizeBar.m_hWnd != NULL)
      m_wndResizeBar.BringWindowToTop();
   COleIPFrameWndEx::RecalcLayout(bNotify);
   CWnd *pWnd = GetActiveView();
   if (pWnd != NULL)
      pWnd->BringWindowToTop();
   if (m_wndRulerBar.m_hWnd != NULL)
      m_wndRulerBar.BringWindowToTop();

   // at least 12 pt region plus ruler if it exists
   CDisplayIC dc;
   CSize size;
   size.cy = MulDiv(12, dc.GetDeviceCaps(LOGPIXELSY), 72) + 1;
   size.cx = dc.GetDeviceCaps(LOGPIXELSX) / 4; // 1/4"
   size.cx += HORZ_TEXTOFFSET;                 //adjust for offset
   size.cy += VERT_TEXTOFFSET;
   if (m_wndRulerBar.m_hWnd != NULL && m_wndRulerBar.IsVisible())
   {
      CRect rect;
      m_wndRulerBar.GetWindowRect(&rect);
      size.cy += rect.Height();
   }
   m_wndResizeBar.SetMinSize(size);
}
