> Dear Squeakers,

> I have always had a hard time learning anything until I had a project to
> do it around.  Well that time has come.
>
> I need to write an app. that will let me run one application inside
> another.  I would like to have a cad type app. running in a window and
> then be able to over lay that cad app. with another app.  that lets me
> put hot spots on the cad app.  These hot spots will have the ability to
> show a colored outline around their perimeter.  That outline we would
> like to be able to turn on and off or make blink.  The purpose of the
> hot spot is to train people how to use the cad app.  by showing them
> where to pick menu items and enter data etc.
>
> So the whole things runs like this, we start the cad app. and the tutor
> app.  The tutor app. step by step shows the student where and what
> bottoms to pic and where and what data to enter.  As they enter etc. the
> app.  actually functions and they are able to create in the cad app.
> Kind of a training wheel effect.
>
> Can any one tell whether or not I could do this in Squeak and kind of
> help me do it.  I do have a nephew who is a good programmer but has
> never used Squeak of small Talk and I would like to get  him help me do
> this app.  start using Squeak.
>
> Can any one point in the right direction?  I would like to do the same
> thing for learning Squeak.  Once we learn how to do it for the cad app.
> I will do it for the Squeak community and make it free.
