Re: [squeak-dev] The Inbox: Collections-ul.564.mcz

I guess there's infinite recursion in Array's printing method too... An Array containing itself? Obviously that's a rare structure the system has never dealt with. Do you think there'll be any other traversing methods that might be affected?

Text cursor, text selection drag/drop, and drag-transfer morph
by Marcel Taeumel 27 Feb '18

27 Feb '18

Hi, there. :-) In the last two days, I had fun with text selections. You can now drag a selection and drop it somewhere in a(nother) text morph --- if you enable the preference "Draggable Text Selections". As usual, hold [SHIFT] for copy, otherwise it will move. I also changed TransferMorph to make use of UI themes. You might have to rebuilt your themes via "UserInterfaceTheme cleanUp: true" to see the change. That's all for this year. :-) Merry Christmas everybody! Best, Marcel P.S.: Please forgive my strange mail application to prefix this list with "Hanh Ho Si via". I am still in the process of figuring out how to control it.

MQTT for Squeak?
by tim Rowledge 02 Feb '18

02 Feb '18

I’m having all sorts of fun making some weather station and environmental sensors with assorted Pi and ESP8266 boards and I need a nice way to make the sensor nodes report back to base. Since the ESP8266 modules don’t run squeak (shame!) I’m using Arduino-c++ (blech) on them, and since the weather sensor code already existed in python (double-blech) I’m using that on the weather-pi board. I’ve been recommended to look at MQTT as a way to bind them all together and from what little sense I can make of the assorted stuff that googling had lead me to (good grief, so much acronym laden gibberish) it looks like it might do the job. Googling for a squeak mqtt package has revealed nothing thus far so I’m now appealing to the list for any news. tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Useful Latin Phrases:- O! Plus! Perge! Aio! Hui! Hem! = Oh! More! Go on! Yes! Ooh! Ummm!

app in app
by Chuck Smith 31 Jan '18

31 Jan '18

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. Sincerely, Chuck Smith

However there seem to be some classes left in the system, see screen shot. So there was removal but it seems it was not done completely.
