WHAT IS GRIDPLUS:
====================

GRIDPLUS is a package intended to simplify GUI screen layout
development for Tcl/Tk programmers. It is a "Grid" based layout system
which  builds on, simplifies and extends the existing grid manager.
GRIDPLUS layouts are defined as a hierarchy of grids. Each cell in a
grid  consists of two elements. These will usually be a text label and
some other widget such as an entry. It is also allowed to have just
one element in a cell, or a cell which is empty. GRIDPLUS grids can
also be stretched to neatly fill the cells in which they are
positioned.

While the GRIDPLUS grid can be used "native", GRIDPLUS commands/
options exist to create grids of Buttons, Checkbuttons, Dropdowns
(Comboboxes), Entries, Menubuttons, Links and Radiobuttons. All places
where text can be displayed make use of the TCL message catalogue
acility.

In effect GRIDPLUS is much more than an alternative to the grid
geometry manager, it provides most, if not all, of the facilities
required to build complete screens/windows. Although aimed at
producing data entry/update/display form screens for database
applications, it may be useful for other tasks.

GRIDPLUS also includes the following features:-

*) Scrollable text widget.
*) Scrollable tablelist.
*) Scrollable tree widget.
*) Basic notebook type widget.
*) Simple drop-down menus.
*) Simple method to specify widget traversal order when using the TAB
key to navigate the screen.
*) A group facility to enable/disable groups of widgets and menu
options.
*) Facility to include non-GRIDPLUS widgets in groups.
*) Simple pattern/procedure based entry validations.
*) Works with toplevel windows.
*) ...and much, much more!!
