Content
|
|
|
|
This directory contains the demo programs for STk. There are several
|
|
categories of demos available from here:
|
|
o STk demos: They correspond to program which don't use CLOS like
|
|
object extension of STk. These demo are quite simple and they
|
|
often mimic original Tcl/Tk demonstrations
|
|
o STklos demos: These demonstration programs use the STklos object
|
|
Extension of STk. The code of most of these demos has been kept
|
|
short to illustrate the basic of STklos programming.
|
|
o Html demo: This demo is in fact an overview of STk/STklos that I
|
|
have used once in a presentation of STklos. The pages accessible
|
|
from this link present STk but also contains links or Scheme
|
|
applets which illustrate the kind of things that can be done with
|
|
the STk browser. Of course, to properly execute the applets
|
|
contained in theses pages, you need to run the STk Html browser
|
|
(see below).
|
|
|
|
Running demonstration programs without installing STk
|
|
|
|
If you want to run a demo BEFORE a complete installation of the STk
|
|
package, you must use the shell script ../Src/test-stk in order to run
|
|
the interpreter (this shell script set some variables to run properly
|
|
the interpreter without installing it).
|
|
|
|
Running demonstration programs in the STk web browser
|
|
|
|
STk provides a simple Web browser which can be used to launch the demo
|
|
of this directory. If you are not running it now, you can type the
|
|
following command:
|
|
|
|
../Src/test-stk -f S-scape README.html
|
|
|
|
at the shell prompt.
|
|
|
|
1. STk demos
|
|
|
|
1.1 Basic STk demos
|
|
|
|
* hello.stk
|
|
This is the traditional first program. This program creates a single
|
|
button that you can click on.
|
|
Run with : ../Src/test-stk -f hello.stk
|
|
|
|
* browse.stk
|
|
A simple Unix file browser. The code of this demo is less than a page.
|
|
Run with: .../Src/test-stk -f browse.stk
|
|
|
|
1.2 Basics of STk programming
|
|
|
|
* wtour.stk
|
|
This is a rewrite of the Tcl/Tk wtour2.0 in Scheme/STk. Use the menus
|
|
to navigate through different lessons. You can make changes to the
|
|
lesson source code; click on the Apply button to see the results of the
|
|
changes.
|
|
Run with: ../Src/test-stk -f ./wtour.stk ../Contrib/STk-wtour
|

1.3 Client/Server Demos
|
|
|
|
* server.stk
|
|
A simple server showing how to use the socket package. It creates an
|
|
xterm window in which a read-eval-print-loop is executed. When the
|
|
window is closed or when an error occurs, the socket is closed
|
|
Run with: ../Src/test-stk -no -f server.stk
|
|
|
|
* mc-server.stk
|
|
A multiple-clients server. On Unix, you can use several telnet sessions
|
|
to discuss with the server. Each discussion has its own dedicated
|
|
channel. Type (exit) at the STk when you want to exit the demo.
|
|
Run with: ../Src/test-stk -load mc-server.stk
|
|
|
|
1.4 Fun and Games
|
|
|
|
* turtle.stk
|
|
A Logo turtle package + some demo functions.
|
|
Run with: ../Src/test-stk -f turtle.stk
|
|
|
|
* hanoi.stk
|
|
Hanoi towers animation.
|
|
Run with: ../Src/test-stk -f hanoi.stk
|
|
|
|
* queens.stk
|
|
The queens problem. You can do it yourself (and it will make sure you
|
|
follow the rules) or you can ask it to solve the puzzle starting with a
|
|
given board configuration.
|
|
Run with: ../Src/test-stk -f queens.stk
|
|
Comment: This code is a contribution of Grant Edwards

|
<grante@rosemount.com)>
|
|
|
|
* stetris.stk
|
|
This is a falling block game not unlike tetris(tm) :). It is
|
|
implemented in STk just to prove it can be done, and as a challenge to
|
|
TCLers. It starts slowly and becomes faster and faster. Have fun.
|
|
Run with: ../Src/test-stk -f stetris.stk
|
|

|
|
|
|
* ttt.stk
|
|
A 3D Tic-Tac-Toe, where the board is 4x4x4, a 3 dimensional board of
|
|
four planes with four rows and four columns each.

|
|
1.5 Misc
|
|
|
|
* console-demo.stk
|
|
This is a simple demo showing a repl loop in a console.
|
|
Run with: ../Src/test-stk -f console.stk
|
|
Comment: This demo is useful for Unix users only, since under Win32 STk
|
|
is started with such a console.
|
|
|
|
* colormap.stk
|
|
This is a simple color palette written in STk.
|
|
Run with: ../Src/test-stk -f colormap.stk
|
|
Comment: Note that this program is no more really useful since STk
|
|
offers now the function Tk:choose-color which allow to choose a color
|
|
by name or by value.
|
|
|
|
* stkfontsel.stk
|
|
This is a simple program which uses the STk font chooser.
|
|
Run with: ../Src/test-stk -f stkfontsel.stk
|
|
|
|
* small-ed.stk
|
|
A small editor to create enhanced text
|
|
Run with: ../Src/test-stk -f small-ed.stk
|
|
Comment: This editor use a ad-hoc format for saving file and was used
|
|
for the help buttons of various widgets in old versions of STk. It will
|
|
not be developed anymore since the preferred format for help is now
|
|
HTML.
|
|
|
|
* showvars.stk
|
|
A variable shower: this program shows the value of three variables
|
|
(named a,b and c) Changing the value of one of these vars (with a set!
|
|
for instance) will redisplay its new value immediately. Run with:
|
|
../Src/test-stk -load showvars.stk
|
|
|
|
* inspector.stk
|
|
A simple demo of the inspector on Tk widgets
|
|
Run with: ../Src/test-stk -f inspector.stk
|
|
Comment: Does not work with this version of STk
|
|
A new version of the inspector is in practically finished and will be
|
|
soon released.
|
|
|
|
* term.stk
|
|
A simple terminal emulator (a kind of xterm, but in a text widget).
|
|
Run with: ../Src/test-stk -f term.stk
|
|
Comment: Users of Glibc2 (aka libc6, or RedHat 5.0 users): This program
|
|
has problems with new release of the libc under Linux, if your shell
|
|
has the line editing mode set. To avoid the problem you can
|
|
o disable the line editing mode of your shell
|
|
o set the SHELL variable to a dumb shell (e.g. ash)
|
|
o link STk with the old libc
|
|
o don't run the demo :-)
|
|
|
|
2. STklos demos
|
|
|
|
All the standard Tk widgets have been wrapped in STklos classes. As a
|
|
result, in STklos, Tk widgets are seen as instances of STklos classes.
|
|
There are two kinds of STklos widgets:
|
|
o Simple widgets which map one to one the Tk standard widgets
|
|
o Composite widgets which are built from simple Tk widgets (or even
|
|
simpler composite widgets).
|
|
Demonstration programs accessible from this page use indifferently
|
|
simple widgets and composite widgets.
|
|
|
|
2.1 Basic STklos demos
|
|
|
|
* hello.stklos
|
|
This is a simple rewriting of the hello.stk demonstration in STklos
|
|
Run with: ../Src/test-stk -f hello.stklos
|
|
|
|
* browse.stklos
|
|
This is a simple rewriting of the browse.stk demonstration in STklos
|
|
Run with: ../Src/test-stk -f browse.stklos
|
|
|
|
* stklos-demo.stklos A simple demo written in STklos.
|
|
Run with: ../Src/test-stk -f stklos-demo.stklos
|
|
Comment: What is interesting in this demo is not what it does, nothing
|
|
specially fancy, but how it is easy to program, IMHO.
|
|
|
|
* stklos-demo2.stklos Another simple demo written in STklos.
|
|
Run with: ../Src/test-stk -f stklos-demo2.stklos
|
|
Comment: Here again, what is interesting in this demo is not what it
|
|
does, nothing specially fancy, but how it is easy to program, IMHO.
|
|
|
|
* classbrowse.stklos This demo shows the STklos class browser.
|
|
Run with: ../Src/test-stk -f classbrowse.stklos
|
|
|
|
2.2 STklos widgets
|
|
|
|
* widget.stklos
|
|
A tour of the Tk widgets. This demo shows all the Tk widgets. This is a
|
|
rewriting in STklos of the big Tcl/Tk demo widget.tcl. For each widget
|
|
demo accessible from this program, you can see the source by just
|
|
clicking the "See code" button. You can modify the code and test your
|
|
modified version by clicking the button "Rerun demo"
|
|
Run with: ../Src/test-stk -f widget.stk
|
|
Comment: This demo illustrate only the simple widgets (the ones of the
|
|
Tk library). For a composite widgets demo look at the
|
|
stklos-widgets.stklos program.
|
|
|
|
* filebox.stklos
|
|
This is a simple program which uses the <File-box> composite widget. A
|
|
<File-box> is a file requester with file name completion (on the Tab
|
|
key).This widget is itself a composition of various composite widget
|
|
classes.
|
|
Run with: ../Src/test-stk -f filebox.stklos
|
|
|
|
* stklos-widgets.stklos
|
|
A quick demo of some of the STklos Composite widgets which are
|
|
available in this release.
|
|
Run with: ../Src/test-stk -f stklos-widgets.stklos
|
|
Comment: This code is a contribution of Drew Whitehouse
|
|
<Drew.Whitehouse@anu.edu.au>.
|
|
|
|
2.3 STklos Applications
|
|
|
|
* calc.stklos
|
|
This is a simplistic calculator.
|
|
Run with: ../Src/test-stk -f calc.stklos
|
|
|
|
* tkcolor.stklos
|
|
This is a simple color picker written in STklos. Clicking the left
|
|
mouse button in the color box sets the text color to the chosen color.
|
|
Clicking the right button sets the background color. The Select button
|
|
sets the selection to a string which can be used (by pasting it in an
|
|
xterm window) as argument of most X11 applications to set their
|
|
foreground and background color.
|
|
Run with: ../Src/test-stk -f tkcolor.stklos
|
|
|
|
* amib.stklos
|
|
A Mini Interface Builder.
|
|
Run with: ../Src/test-stk -f amib.stklos
|
|
Comment: The current version of AMIB allow you to:
|
|
o place objects on a plane by drag and drop
|
|
o resize objects
|
|
o displace objects
|
|
o change all the slots of an object (color, font, value, ...)
|
|
o save an interface to reload it later in an application
|
|
However it is far from a really usable interface builder (but after all
|
|
it is only a 600 lines of code application!!!!)
|
|
|
|
* S-scape.stklos
|
|
The STk web browser. You are probably using it while seeing these
|
|
lines.
|
|
Run with: ../Src/test-stk -f S-scape.stklos
|
|
