From: shags72 on 30 Jan 2010 21:10 HI again. I like I have said before am pretty new at writing tcl code which is the only code I know at this time and I want to write a simple ap or interface or something like it that does a simple math equation. I would like it to be an icon to click on and have it bring up a gui and have some input and a return. I do not know how and I do know some basic tcl but no tk. Any help would be great and Thanks in advance.

Kind regards Jan

One of the applications in the Model Railroad System in fact implements 'a simple math equation'--Ohm's Law.

Just trying to learn how to do this as I write simple tcl in an embedde system but never get to write anything with an interface. I like to learn and I thought this would be a good starting point. Thanks I will download the file you suggested Robert. |
