CDocument::GetNextView

Call this function to iterate through all of the document's views.

virtual CView* GetNextView( 
   POSITION& rPosition  
) const;

Parameters

  • rPosition
    A reference to a POSITION value returned by a previous call to the GetNextView or GetFirstViewPosition member functions. This value must not be NULL.

Return Value

A pointer to the view identified by rPosition.

Remarks

The function returns the view identified by rPosition and then sets rPosition to the POSITION value of the next view in the list. If the retrieved view is the last in the list, then rPosition is set to NULL.

Example

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