GRIDPLUS 2.1 has been released and is available from:

New and Enhanced Features

*) New GRIDPLUS "container" command mode to create a frame which
   can contain toplevel windows.
*) New "gpselect" command to select a tablelist row or tree node.
*) New "gpinsert" command to select a tablelist row or text line.
*) The "gpmap" command can now also map array elements to GRIDPLUS
   widget values.
*) The window command mode now has an "-in" option to put the window
   into a container.
*) Variable Substitution now also works for the notebook layout.
*) The text command mode now has an "-font" option to set the display
   font when not using tags.


*) The -title option for the GRIDPLUS layouts with a name ending with
   ".main" no longer sets the window title.

Bug Fixes

*) The Notebook now works in toplevel windows.
*) The tablelist "-columnsort" now works.


GRIDPLUS2 is a Tile based version of GRIDPLUS. Whereas GRIDPLUS
Version 1 has features to control widget style as well as window
layout -  GRIDPLUS2 assumes that the Tile style engine facilties will
be used to  control widget styles. GRIDPLUS2 instead provides
SIGNIFICANTLY  ENHANCED screen layout/desgin functionality - which can
further reduce  the coding required to achieve the desired widow/
widget layout.

One of the main enhancements is the new GRIDPLUS2 Widget Grid. With
GRIDPLUS1 it was only possible to create one type of widget in a
particular Grid (Buttons, checkbuttons, entries etc.). In order to
mix  widgets in a Grid it was neccessary to create additional Grids
for the  other widget types and then "embed" them into a parent Grid.
The new  widget Grid allows all of the GRIDPLUS widget types to be
mixed in the same Grid.

See for
further  details.

GRIDPLUS is a package intended to simplify GUI screen layout
development for TCL/TK programmers. GRIDPLUS is the second in a
series  of packages aimed at producing a framework for  development
and  distribution of "database" applications written in Tcl/Tk, but I
feel that some of the packages may also be of more general interest.
The  first package ICONS, released 2002 (
icons), was originally developed to be used with GRIDPLUS.

Firstly: GRIDPLUS is not a "Visual" design tool.

GRIDPLUS 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 facility.

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
*) Facility to include non-GRIDPLUS widgets in groups.
*) Simple pattern/procedure based entry validations.
*) Works with toplevel windows.
*) ...and much, much more!!
