[ANN] Idea icon pack now in Configuration Browser

by Esteban Lorenzano

Hi, I made a configuration to install the new Idea Icon Pack from configurations browser for Pharo 4. You can install it and then choose your new icon set in settings. You can also manual install them by: Gofer it smalltalkhubUser: 'Pharo' project: 'MetaRepoForPharo40'; configurationOf: 'IdeaIcons'; loadStable. ThemeIcons current: #IdeaUIThemeIcons asClass new. âIn Pharo 4, you might need to execute thisâ AbstractNautilusUI resetIconCaches. This icon pack works also for Pharo 3 If you lost it, here a couple of screenshots:

I am pleasantly surprised by the small amount of code needed to create something like this. Not so much by the effort in finding out how to do these things. I found it necessary to look in a Squeak image to see how other Morphs/Morphic applications dealt with events, especially when tracking the hand. There are a few things that I've not yet solved: - I've added #isMorphicDraw and #isMorphicDrawShape to make sure only MorphicDraw shapes don't escape from their panel, and no other morphs are added to the panel. Is there a more elegant way to achieve that? - In MDCard I've added TextMorphs to the shape. They don't like right clicks. MNU TextMorph>>editView. - How do I tell a PolygonMorph to use bezier curves with a starting direction for the end points? Stephan

Phil I proposed to the head of the engineer to see if one of the guys working on databases could be interested by a one month project. Now I have no idea if they will like it/have the time.
