CListCtrl & theCtrl = GetListCtrl
-
I saw these lines in an example code. I am not clear about it.
CListVieiw::OnInitialUpdate();
CListCtrl & theCtrl = GetListCtrl();My questions are (1) Is GetListCtrl()( on the second line) a member function;Which class does it belong to? (2) what does the '&' mean at the left hand side?

Thank you DavidCrow for your reply. I wonder what exactly is the role of GetListCtrl(); generate a instance of ListCtrl? or sth else?

To get a reference to the list control associated with the view.

Thanks again. However, what if there are more than one list controls associated with the view.

Then you'd have more than one view.

You mean ONLY one ListCtrl can be associated with one view? If so, Why there may be more than one ListCtrl in a dialog Or, I misunderstand the view concept. I think a dialog essentially is a view.

So, for a view derived from a non CFormView, GetListCtrl is used to get the reference of the ListCtrl associated with it. for a view derived from a CFormView, how to get the references of ListCtrls associated with it. What command should be used.
