Celebrating the upcoming Open Data Day (March 5) with Pharo

by Offray Vladimir Luna CÃ¡rdenas

Hi all, I just want to share a post made on the Open Knowledge Foundation Forum talking about what we're doing in our local community to celebrate the Open Data Day: https://discuss.okfn.org/t/our-poryect-and-hackathon-workshop-for-the-open-… Pharo, Roassal and Moose will be an integral part of our celebration. As I said in the link, we're going to try some treemapping techniques. I know about Quick Silver, but if any has some other advice, is very welcomed. Probably I will be making some questions here and in the chat channel regarding treemapping and some SQLite queries to get the proper info, so I'll keep you posted on how our pharo powered workshop/hackathon for the celebration of the Open Data Day advances. Cheers, Offray

Representing objects and actions on them in a list? And we want that in a matrix and tree too, not just linear. Stephan

This: [1] is what I would like to do. I found it in an old thread: [2] but it is a prototype. I wondered if there was an object able to do it in the framework :-)...

by Julien Delplanque

I would like to have a ListModel holding objects I can edit a value using the TextModel and apply my modification using the ButtonModel.

I never tried anything like this, I do not think it is possible. What you are trying to do seems strange to me, what is the use case you want to implement? > On Mar 2, 2016, at 17:06, Julien Delplanque <julien(a)tamere.eu> wrote: > > Hi everyone, > > I can't find how to display Spec widgets in a ListModel, is it possible? > > I would like to have a list model holding, at each row, a TextModel and a ButtonModel. > > Thanks in advance, > > Julien > > ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD and RyCh labs - Computer Science Department (DCC) - University of Chile

Is there a way to display Spec widgets in a ListModel?

by Julien Delplanque

Hi everyone, I can't find how to display Spec widgets in a ListModel, is it possible? I would like to have a list model holding, at each row, a TextModel and a ButtonModel. Thanks in advance, Julien

Re: [Pharo-users] [Issue tracker] Please check old issues to prepare for release!

by Paul DeBruicker

I submitted slices for 15733 & 15819 to the Pharo 50 Inbox. I can't see where in the image the 'format on accept' setting has gone. Is it there and I can't find it or something else? -- View this message in context: http://forum.world.st/Issue-tracker-Please-check-old-issues-to-prepare-for-… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
