SDL Delphi Component Suite

The unit RepList contains the Delphi™/C++Builder™ visual component TReportListView which provides a list view similar to the Delphi™/C++Builder™ component TListView with the ViewStyle set to vsReport. TReportListView is up to a factor of 100 faster than the standard list view, provides a sorting facility, and an enhanced layout of the list. More details can be found in the online help pages.

The unit REPLIST is part of the SDL Component Suite.
