This directory contains an extension to Tcl/Tk (called BWidget) that provides
new and enhanced widgets. It is not a new interpreter but simply Tcl/Tk files
that provide the functionality. Therefore, there is nothing to compile and it
only requires 2 lines of code in your Tcl/Tk script to use the new widgets.
Some of the new widgets include
On mouse over help balloons
Tabbed notebook panes - like worksheets in Excel
Directory tree listing
Combination box or drop down option list
Progress bar
Many others
For a demonstration of the new widgets available perform the following
cd demo
wish demo.tcl
It may take some time to load, but it demonstrates all or most of the new
features.
To use these widgets with GRASS Tcl/Tk scripts (including tcltkgrass) then add
the following two lines to your main Tcl/Tk script
lappend auto_path $env(GISBASE)/bwidget
package require BWidget
Then simply use the new widgets as if they were already part of Tcl/Tk. To find
out more information on using the new widgets see the manual pages in
./BWman/index.html
For more information on BWidget see their home page at

or read the README file in this directory.
