       The last thing I want in a GUI shell interface is widgets, with the
       possible exception of a string entry widget.

       What I need is the ability to open a window, draw lines,
       rectangles, etc., set a font and write text (including an interface
       to the XTextWidth function), receive keypresses and mouse clicks
       (with co-ordinates).

       One of the uses I have is for creating crossword puzzles. The grids
       normally contain 225 squares; I sure as hell don't want to create
       225 widgets to do something that I can do with a few lines of code.

       If I have the mouse co-ordinates, I can easily calculate which
       square was clicked, with vastly less overhead than with a widget. I
       do it already, using the mouse in an xterm window.

       In my article at UnixReview.com, I present a shell script which
       prints buttons on the screen and performs actions when one is
       pressed. Adding a button and associating an action with it requires
       an added label as argument to a function call and a single line of
       script to perform the action.

       The article ends with the instructions to add another button to the
       script, and clear the screen when it is pressed. All it involves
       is:

           Change:

             print_buttons "$mv_str" "Exit"

           to:

             print_buttons "$mv_str" "Clear" "Exit"

           and:

             2) break ;;

           to:

             2) clear ;;
             3) break ;;

       No widget interface is going to be that simple.

       The article is at:
       <http://www.unixreview.com/documents/s=9823/ur0507a/ur0507a.html>
       and the script at:
