It gives the expected answer on OSX, which is the directory where the image lives, and does not "explain" the OP's problem. :-) Pierce

Re: [Pharo-users] when was pharo announced to the world?

by Sven Van Caekenberghe

Hi Mayuresh, You mean like a birthday ? Good idea ! I'll leave it to StÃ©phane or Marcus to propose a date, Wikipedia says Pharo 1.0 was released on April 15th. But Pharo was of course already active for quite some time before that.

In the worst case you'd need to create RTView (or something similar, I read the docs long ago) subclasses to wrap pluggable widgets. BTW, when I browse Roassal2-Core I see almost all the classes are undocumented. This makes it a bit hard to infer high-level design of the code (it's common for me to work with Nautilus and pen&paper notebook for this...) - is there a high-level overview of Roassal architecture somewhere?

when was pharo announced to the world?

by Mayuresh Kathe

hi, a trivial question; when was pharo announced to the world? we all could use that day as the one to collectively chip in some amount towards the project's operational expenses. a nice burst of funds, once a year might be a good thing compared to a funding drive (as some of the other open source projects carry out). ~mayuresh

Hi Sebastian, for building UIs I would go with Spec. It however does not support adding widgets without decoration straight to the desktop. Whatâs wrong with having them open in different windows? If the windows keep references to each other they can interact (more specifically if the different ComposableModels keep references to each other they can use each othersâ public API â¦ which you define as their implementer). As for pretty graphs, I recommend Roassal2 by the ObjectProfile guys. It however cannot embed widgets in the graph as this is not its focus.

Re: [Pharo-users] Spec, Morphic, lists, multiple selection and drag&drop

Ctrl + Left click, which does this for most other multi-select lists in existence, doesn't do anything at all. Is this expected? I have no other system to check this right now.
