The one known purpose of the ISubItemCallback interface is to provide a set of callback functions for a List-View control. The interface is implemented by any component that has access to a List-View control and wants to participate in the handling of subitems. To register this set of callback functions for a List-View control, pass the address of the ISubItemCallback interface as the argument to the SetSubItemCallback method of the control’s IListView interface.
The ISubItemCallback interface is supported by COMCTL32 versions 6.10 and higher.
Though new for Windows Vista, this interface is not documented by Microsoft in the January 2007 edition of the Software Development Kit (SDK) for Windows Vista.
