YstokGrid
YstokGrid is a CAPI-based grid widget for LispWorks®.
The grid provides convenient GUI framework for working with data in tabular
form. The main design purpose was to present RDBMS records in rows. You can edit in place,
add, or delete records.
An instance of the ygrid class can be included into any
CAPI interface window as an ordinary pane. It requires
Ystok-Library and
Ystok-Widgets.
