Re: [Pharo-project] Modeling user event

Great, I will review it. Now I want a solution to do it cleanly and long-term sustainable within Pharo. So this mean no hurry for us to get it in first DrGeo tablet iteration and take the necessary time to cooperate with the pharo community.

Re: [Pharo-project] TabbedPane Class/ Package / Workspace browsers

by S Krish

The usual multi window is always available if you the Open In Tabs option... is defaulted to false. So compose what you have in the tabbed pane and open the rest.. but even the tabbed pane can be smart to open all windows but except those that have #canOpenInTabbedPane property set to false. Scale/ Flex as you want.. but fix it for the newbies.

Re: [Pharo-project] TabbedPane Class/ Package / Workspace browsers

by S Krish

Surely I have no problems, except that my experiments are currently racing faster than the code process. My code has a good fraction of hacks, I do not like.. Let me clean them up and I will integrate to whatever makes sense for Pharo. Till then I will share it as a DirtyButCoolExperiments. My first goal is to convince a large set of developers to look upon Smalltalk as a cutting edge, new Programming Paradigm not just a language, an IDE.. This IDE/ UI/ View Framework / Tablet Interface are works in that direction. To make them feel better when they open a Pharo IDE, accustomed as they are to other interfaces and Windows primarily Long way to go on that still..

Re: [Pharo-project] HTTPS

by Dale Henrichs

Sven, I am looking to include features in Metacello that require https. I have tried "copying the proper file to the proper place" and my mileage certainly does vary. I have failed with 3 of the vms that I have tried. I have no idea what I am doing wrong. I believe that you are able to create a vm with squeaksll installed, but I don't have the option of telling folks to get their vm from Sven if they want to use Metacello:) I just assume that I won't be the only one to have trouble, either. If someone gave me the explicit instructions ... I'm obviously doing something wrong ... I would have more confidence that it would be a practical route to take, but pointing to a vm that works doesn't help. Using curl (installed and worked the first time on my mac:) via OSProcess is just simpler to get running. I'm just downloading a file so I am doing nothing fancy and curl works fine (and is easy to install). I still would prefer to use Zodiac.

Hi Guido-- > I always thought, the IMAGE *is* already an OO database!?? Yes! Naiad, Spoon's history system, stores source code in a dedicated second image, via remote messaging.
