This directory contains a collection of programs to demonstrate
the features of the Tk toolkit. The programs are all scripts for
"wish", a windowing shell. If wish has been installed in /usr/local
then you can invoke any of the programs in this directory just
by typing its file name to your command shell. Otherwise invoke
wish on the file using the "-f" switch to wish, e.g. "wish -f hello".
The rest of this file contains a brief description of each program.
Files with names ending in ".tcl" are procedure packages used by one
or more of the demo programs; they can't be used as programs by
themselves so they aren't described below.
hello - Creates a single button; if you click on it, a message
is typed and the application terminates.
widget - Contains a collection of demonstrations of the widgets
currently available in the Tk library. Most of the .tcl
files are scripts for individual demos available through
the "widget" program.
ixset - A simple Tk-based wrapper for the "xset" program, which
allows you to interactively query and set various X options
such as mouse acceleration and bell volume. Thanks to
Pierre David for contributing this example.
rolodex - A mock-up of a simple rolodex application. It has much of
the user interface for such an application but no back-end
database. This program was written in response to Tom
LaStrange's toolkit benchmark challenge.
tcolor - A color editor. Allows you to edit colors in several
different ways, and will also perform automatic updates
using "send".
rmt - Allows you to "hook-up" remotely to any Tk application
on the display. Select an application with the menu,
then just type commands: they'll go to that application.
timer - Displays a seconds timer with start and stop buttons.
Control-c and control-q cause it to exit.
browse - A simple directory browser. Invoke it with and argument
giving the name of the directory you'd like to browse.
Double-click on files or subdirectories to browse them.
Control-c and control-q cause the program to exit.
dialog - Displays a simple dialog. Click on any button and the
application exits.
size - Takes three arguments: the name of an application, the
name of a widget in that application, and the name of an
integer-valued option for that widget. Allows you to
interactively resize the given option. For example,
start up the dialog demo, then type
"size dialog .bot.middle -pady" for an example.
color - Similar to "size", but modifies a color option. Try
"color dialog .bot.middle -bg" for an example.
tkSquare.c - A very simple widget to provide an example of how to
implement a new widget. When building a new widget you
may find it useful to start from this code.
