Hi Mark - not to distract you, as its good to see someone pushing on the Spec integration with a real use case - but an alternate is a web application. Presumably you are familiar with Seaside but there is another kid in town that Iâve been having a lot of fun with with - CodeParadise - which uses MVP with the UI hosted transparently as minimal client side image (via the magic of Pharo Candle to create a minimal Dom based headless image that runs on the SqueakJS VM) using WebComponents. Iâm still in awe over how this works and brings numerous Smalltalk technologies together (although - seeing Esteban demo a native spec app earlier this month was very cool too). CP is still pretty heavily in development (so the same doc scarcity as well - https://github.com/ErikOnBike/CodeParadise) - but Iâve been helping Erik get Shoelace (https://shoelace.style/components/card) working in it - and that has a decent rich set of UI components that you can hook up (there isnât a tree view though - not sure if thatâs some CSS trickery to accomplish this). There was a presentation on it a few months ago - https://vimeo.com/457353130 Anyway - welcome to Pharo and isnât it fun to pick up on Smalltalk again?

I am currently working on a administrative system to keep track of our sheeps (about 30 ewes and 50-60 lambs a year). It is not finished yet, but if anyone wants I can make the currently private git public or give access.The intended user is my wife who is not an easy customer :-) It uses a sqllite database, and a home rolled orm - I can provide a sample database as well. The code is in English, while the labels and such is in Danish. It tries to strike a balance between generic structures and performance, for example using pragmas in the domain model to drive important parts of the gui. Best, Kasper

hi, ah, those are correct presenters/applications. if you want to make a gtk application at a point you need to configure it (hence CrGtkConfiguration). CrApplicationStarter is because in different platforms you may have different ways of start the application (for example macOS may need a system menu... which anyway so far I have been unable to do, but still ;) ) the other extensions were for needs of the application but indeed some of them may arrive (and some of them already this) to vanilla spec (firstResponder is now "defaultKeyboardFocus", for example...). this application is one of the ones I use to test concepts that may or may not make their path to vanilla Spec :) Esteban On May 11 2021, at 7:30 pm, mark.odonoghue.2010(a)gmail.com wrote: > Hi Esteban > > Iâm new and may be wrong and apologise if so â¦ ! > It just looked like the Crono package has a few things I didnât expect : > CrApplicationStarter > CrGtkConfiguration > > CrWindowConfiguration > > SpPresenter extension firstResponder > > SpWindowPresenter extensions (2) > > These âCrâ classes seem to have some more general purpose behaviours that other SpApplications could use? > And I would have thought the Gtk configuration would be outside Crono too? > Also, presumably the extensions are candidates for repackaging outside/above Crono â¦.? > This may be just a naming and packaging thing rather than any criticism of design. > > In summary, as a simple consumer of the framework there was (some) surprising detail in the Crono package and classes that didnât seem relevant to any new application I would be writing. > Hence I would have hoped not to have to clone these details (or even deal with themâ¦). > Does that sound fair? - or do I have the wrong end of the stick !! > > > Cheers > Mark

Hi Esteban Iâm new and may be wrong and apologise if so â¦ ! It just looked like the Crono package has a few things I didnât expect : * CrApplicationStarter * CrGtkConfiguration * CrWindowConfiguration * SpPresenter extension firstResponder * SpWindowPresenter extensions (2) These âCrâ classes seem to have some more general purpose behaviours that other SpApplications could use? And I would have thought the Gtk configuration would be outside Crono too? Also, presumably the extensions are candidates for repackaging outside/above Crono â¦.? This may be just a naming and packaging thing rather than any criticism of design. In summary, as a simple consumer of the framework there was (some) surprising detail in the Crono package and classes that didnât seem relevant to any new application I would be writing. Hence I would have hoped not to have to clone these details (or even deal with themâ¦). Does that sound fair? - or do I have the wrong end of the stick !! Cheers Mark

Agree ! I think it would be very valuable to have a "build an application from scratchâ tutorials/talks/guide. Perhaps it would also result in a small well designed sample application (e.g. Personal Organiser/To Do Lists) that new folk can work their way through; once they have got familiar enough with the language and tools using existing resources (i.e. no need to repeat basic concepts).

Hi Sebastian Thanks for providing your application - No problems loading it on Windows 10 . Your application is pitched at the right level for the GUI work that I need to do. It looks like it will be very useful indeed. It is also really good to be able to compare it to Estebanâs more complex example, as Iâm sure having both will help me with problem solving and better understanding of the Spec2 framework. Many thanks :-) Mark

I am playing with the idea of setting a bunch of techtalk sessions to "build an application from scratch". I need to book the time but I think it can be a good idea.
