Welcome to the main webpage for
Tcl/Tk GUI Programming - have fun edition

THIS COURSE doesn't get enough demand to run in the normal iCanProgram format. As such I've left the lessons up on the web for your perusal. This course doesn't have a mailing list. Should you have any questions about the material don't hesitate to contact me directly at the info email address.

ALSO A REMINDER that this course is being offered for free in return for a voluntary donation to Cancer Research in memory of Linda. If you don't know how to reach your local Cancer Research charity in your country you might find info here. For those students who are in Canada there is an online donation site here. Please do your part so that we all win.

How does this all work?

Each of these lessons are intended to be FUN as well as instructive.

If the course was operating in the iCanProgram format a new lesson link would be enabled below each week. In this format all the lessons are already enabled.

These lessons will progress from the simple concepts to more elaborate concepts. At the end of lesson 8 you will be capable of writing a ticker tape program similar to the demo complete with pull down menus.

When you are enrolled in the normal iCanProgram course you would have been added to the email mailing list.

Mailing List

Mailing lists are used throughout the Internet whenever a group of people with similar interests wants to stay in touch.

Mailing lists work a lot like a magazine subscription. When you decide to join the mailing list you contact the central "subscription office" for that mailing list by email asking to have your email address added to the circulation list.

At that point you would be said to have been "subscribed".

When you have a question that you want to ask the group you simply compose a single email and send it to our mailing list address.

Everyone on the circulation list would automatically receive a copy of your email. It would arrive in their inboxes just like any other email would. It would show that you were the sender. Any replies would also circulate to everyone in the group.

So you can see that a mailing list is nothing other than a convenient way to stay in touch with a whole group of people using email.

Normally a mailing list would have been created for your course. All the other participants would be subscribed as would the course facilitators and programming experts. It will be like doing a team project where you can share ideas and ask other team members for help. In this format mailing list is not active .
