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.
YstokGrid can be included into any
CAPI interface window as an ordinary pane. It requires
Ystok-Library and
Ystok-Widgets.

What Is New in Release 1.1
- Adapted and tested for LispWorks 5.0:
- for LW5, editing pane font can be of variable width.
- for LW5, cursor files are loaded during compilation and are no longer
needed in run-time.
- Added the leftmost non-scrollable (aka frozen) columns feature,
which is controllable by the left-frozen-ncols slot of the ygrid class; they
are always visible when scrolling horizontally similar to the row header.
- Added several event generics and callbacks.
YGrid was tested on LispWorks 4.2-4.4 and 5.0 for Windows. Take a look at change.log for release history.
