CDocument::GetFirstViewPosition

virtual POSITION GetFirstViewPosition() const;

返回值:
返回POSITION值,它用于GetNextView成员函数的迭代。

说明:
调用该函数获得与文档相关的视图列表中的第一个视图。

示例:
// To get the first view in the list of views:
POSITION pos = GetFirstViewPositon ();
CView* pFirstView = GetNextView( pos );
// This example uses CDocument::GetFirstViewPosition
// and GetNextView to repaint each view.
void CMyDoc::OnRepaintAllViews()
{
  POSITION pos = GetFirstViewPosition();
  while (pos != NULL)
  {
    CView* pView = GetNextView(pos);
    pView->UpdateWindow();
  }
}
// An easier way to accomplish the same result is to call
// UpdateAllViews(NULL);
