[Pharo-project] Morph on focus lost

by Sebastian Sastre

Hi guys, quick question, what's the equivalent event of blur on morphs? What event you need to observe in a morph if you need to react to the focus lost in that morph? sebastian o/

Oh yes. May be you did not see it but adding polymorph was the first things we did even if the code was not perfect. I often said to my students if you want to faint or vomit when you open Squeak (at that time I was maintaining squeak3.8or9) then this is normal we are working on it and one day it will be cool.

Like checking if a bug is still a bug in the current version. I'm still learning a lot by trying (and I fail often) to fix something but I nearly always learn something. > > Best regards, > > Sebastian > > > 2012/11/25 dimitris chloupis <thekilon(a)yahoo.co.uk>: >> "eye candy" wise this is exactly the focus of my Ephestos project , Morpheas >> section.

thanks Just start small and work steadily. This is what I do and at the end I learned something I did not know before.

Re: [Pharo-project] dumpfs - inspecting floating point numbers

Indeed this would be really nice. I took some of the mails that nicolas sent to the list and turn them into a little chapter on numbers. It could be a start too. Look at the littleNumber chapter of the deep into pharo book.

[Pharo-project] ProfStef on steroids (was: Athens OpenGL backend - what does it mean?)

by Sebastian Nozzi

Interesting... can you share some details about it already? Or is it too soon...? When I read your past discussion about the help-system not being able to show "figures" (I think Igor pointed it out) I thought: "wait a second, why is it not possible to "embed" Morphs into the text?". I thought I had seen something like that in the past before... (in Squeak). 2012/11/25 dimitris chloupis <thekilon(a)yahoo.co.uk>: > As a first part I am in the process of creating a tutorial generator which > will be ProfStef on steroids for at first offering tutorial for Athens and > later used for any kind of Pharo tutorial.
