示例1: QueryViews

//
/// Return pointer to this document or one of its child documents if the spcecified
/// window parameter is a view associated with the document.
/// \note Unlike 'HasFocus', this method allows you to distinguish whether the
/// document with focus is a child document.
//
TDocument*
TDocument::DocWithFocus(HWND hWnd)
{
  TDocument* pdoc = 0;
  while ((pdoc = ChildDoc.Next(pdoc)) != 0)
    if (pdoc->DocWithFocus(hWnd))
      return pdoc;

  return QueryViews(vnIsWindow, (long)hWnd) ? this : 0;
}

示例2: PRECONDITION

//
/// Calls TWindow::GetFocus() to determine the window with the focus. Searches the
/// list of documents and returns the document that contains the view with the
/// focus. Returns 0 if no document has a view with focus.
//
TDocument*
TDocManager::GetCurrentDoc()
{
  PRECONDITION(GetApplication());
  PRECONDITION(GetApplication()->GetMainWindow());

  HWND hWnd = GetApplication()->GetMainWindow()->GetCommandTarget();
  TDocument* doc = 0;

#if defined(OLD_DOCVIEW)
  // !BB This older implementation of GetCurrentDoc relies on the
  // !BB document's HasFocus method which does not allow 'GetCurrentDoc'
  // !BB to return child documents....
  // !BB
  // !BB This obviously causes some problems (for example, closing a view
  // !BB associated with a child document closes the whole document and
  // !BB all their associated views!).
  // !BB
  // !BB However is there code that relies on this behaviour - Investigate
  // !BB

  if (hWnd && ::IsWindow(hWnd)) {
    while ((doc = DocList.Next(doc)) != 0 && !doc->HasFocus(hWnd))
      ;
  }

#else
  if (hWnd && ::IsWindow(hWnd)) {
    while ((doc = DocList.Next(doc)) != 0 ) {
      TDocument* childDoc = doc->DocWithFocus(hWnd);
      if (childDoc) {
        doc = childDoc;
        break;
      }
    }
  }
#endif
  return doc;
