Re: [Pharo-users] Nautilus + Periscope

by Pavel Krivanek

The main problem is in dynamic UI generation for plugins and own Morphic binding. It was done using several hacks that do not work in the recent Spec version. Some information are here: http://forum.world.st/update-3-0-30448-td4712466.html -- Pavel 2013/11/15 Juraj Kubelka <juraj.kubelka(a)gmail.com> > Hi Pavel, > > I finally installed in Pharo 2.0.

Finding references to traits

by btc＠openinworld.com

If I come in cold to a system and see some class using trait, and then I want to find all classes that use that trait. I have tried a few ways but failed to work it out. The most obvious action "Extended search > references of it" doesn't show them, and neither does any other action I try. How is this done? cheers -ben

I did it but not Spec. Let me know if you need some hints.

Hello Gisela, I've been searching for a way to do that using Spec in Pharo 2.0 seems a tricky one. In Pharo 3 is a lot easier. One alternative solution, though not very nice, is to use a Slider with a vertical layout.... saludos Nacho *Lic.

Re: [Pharo-users] Nautilus + Periscope

by Juraj Kubelka

Hi Pavel, I finally installed in Pharo 2.0. I did not know I have a different image.Thanks for your help and thanks also for the configuration script :-) I would like to use Periscope in Pharo 3.0. Do you have an idea what is necessary to change? I am willing to help with it, but I need some support. First likely I have to learn Spec framework. Right now I have just a white window like in the attachment.

[Spec] How to adding my scroll bar

by Gisela Decuzzi

Hello, I have a component that basically contains lot of widgets and I want to add a scroll bar to it. But I didn't find a way to do this. I'm using Pharo 2.0 (I know 3.0 is better but I needed something stable). My spec is a ColumnLayout with lot of rows. Maybe I should use another? Can someone point me where to look at?

Re: [Pharo-users] NBOpenGL on Pharo 3.0

by StÃ©phane Ducasse

> Hi > > Wanted to let you know that the GLTTRenderingDemo is working again on Windows. > Thanks a lot for your effort! Ricky Now you should really think that JB is doing that on his free time. He is not payed for doing that. We should work on Python security and Moose Python. So what I want to say is that you should consider that Pharo is YOURS and that NBOpenGL too. So let, and if you do not know, learn. JB learned openGL to do something fun during his PhD but it has nothing to do to 3D. It is about security and dynamic language.
