Called by the framework when a visual aspect of an owner-draw list view control changes.
A long pointer to a DRAWITEMSTRUCT structure that contains information about the type of drawing required.
The itemAction member of the DRAWITEMSTRUCT structure defines the drawing action that is to be performed.
By default, this member function does nothing. Override this member function to implement drawing for an owner-draw CListCtrl object.
The application should restore all graphics device interface (GDI) objects selected for the display context supplied in lpDrawItemStruct before this member function terminates.
