Detailed Description

Data feed for Skip and Clip List objects.

This structure is passed to the NewBlock callback by the 'Clip' and 'Skip' List Objects when, due to user scrolling, the objects needs to query the application to supply new data items. The member 'nr' is also a return value of the callback in case of 'Skip' List Object. It specifies the number of rows actually returned. See MCreateSListSkip(), MCreateSListClip() and CmClippedSList for object creation details.
