MFC Question

Recommended Posts

I have a class CGraphicsView, derived from CScrollView. Is there any way I could directly access its public data members from the CMyAppDoc class ( from CMyAppDoc member functions ) ?

hmmmm, sure there''s a design pattern for this somewhere...

Why not impliment an external singleton class that gets created by the view window upon it''s creation, and has a certain amount of access to the window instance (ie, store a pointer to it). The global singleton interface would then allow some form of controlled access (ie, read "safe") that allows communication between the two....

CView derivatives have the CDocument *GetDocument() function. Use that to obtain a pointer to your document object, re-cast it to your CDoc-derived, and use it. Assume that your CDoc have get/set function or the members are public (oh no).

[EDIT] This works only when your Doc/View 'comes in pair'.
