Re: [Pharo-dev] Spec delete method

You can add this to the initialize method of your widget, and in the close method unregister all announcers self whenWindowChanged: [:w | w whenClosedDo: [ self close ] ].

And that means: - making sure it works on all 3 major platforms (at least) and not breaks with new version(s) releases - updates the code, improves it etc - keep image-side code in good shape covered by tests and updated regularly , as Pharo make progress - have a good documentation any volunteers? I could, but i can't , because i already have multiple projects to care about. And i am close to limits of personal physical capabilities to keep things up. I didn't wanted to discourage anyone, but just wanted to remind that 'including into pharo' means a lot more than 'copying files there', otherwise it is not 'including', but planting timebomb which will explode eventually. > Thx > T. > > > [1] http://lists.gforge.inria.fr/pipermail/pharo-project/2011-July/051826.html > [2] http://lists.gforge.inria.fr/pipermail/pharo-project/2011-July/051838.html > [3] http://lists.gforge.inria.fr/pipermail/pharo-project/2011-July/051843.html > -- Best regards, Igor Stasenko.

Ok :) Then there is a hook in Morph for that I think :) (and an announcement in Spec when a widget is built) Ben On Jul 17, 2013, at 3:37 PM, Tudor Girba <tudor(a)tudorgirba.com> wrote: > I guess what Stef means is that he would like to know if there is a way specify custom behavior when a window closes, and then use this for his purpose of unregistering from some announcer. > > Cheers, > Doru > > > On Wed, Jul 17, 2013 at 2:36 PM, Benjamin <benjamin.vanryseghem.pharo(a)gmail.com> wrote: > I do not think it's a UI framework concern to handle model behaviour (like registration to announcement) > > Ben > > On Jul 17, 2013, at 9:40 AM, StÃ©phane Ducasse <stephane.ducasse(a)inria.fr> wrote: > >> Hi ben >> >> I would like to unsubscribe announcement when the window is closed. >> Is there a hook for that in Spec? >> >> Stef >> >> >> >> > > > > > -- > www.tudorgirba.com > > "Every thing has its own flow"

Re: [Pharo-dev] Spec delete method

by Tudor Girba

I guess what Stef means is that he would like to know if there is a way specify custom behavior when a window closes, and then use this for his purpose of unregistering from some announcer.

CameraPlugin for (Pharo) VM

by Torsten Bergmann

We once had a discussion already, to summarize: - the camera plugin from scratch worked according to Bernat Romagosa [1] - Stef checked the scratch license and said this license is not MIT so he do not want to see it in Pharo [2] [3] We didnt move on with this since we thought it is covered by Scratch license or since nobody really cared. But it looks like the Camera stuff is indeed released with MIT license (even before the discussion) I just found by accident this old issue: http://bugs.squeak.org/view.php?id=7654 <quotes> "two plugins that should be made available for standard VMs" "Per communication from Bert Freudenberg, source for CameraPlugin is now available under MIT license:" "Here is the CameraPlugin code under MIT license." </quote> Acccording to this issue the camera code was opened with MIT. The issue also includes the code. Can we check again - default support for camera would be a nice addition to our Pharo universe. Thx T.

I do not think it's a UI framework concern to handle model behaviour (like registration to announcement) Ben On Jul 17, 2013, at 9:40 AM, StÃ©phane Ducasse <stephane.ducasse(a)inria.fr> wrote: > Hi ben > > I would like to unsubscribe announcement when the window is closed. > Is there a hook for that in Spec? > > Stef > > > >
