Re: [Pharo-users] Spec: Populating a playground with a particular content (was Re: Spec: Binding widgets how to)

by Tudor Girba

Hi, For your tabulator example, you can do something like: browser := GLMTabulator new. browser title: 'CÃ³digo'. browser column: #code. browser transmit to: #code; transformed: [ :text | GTPlayPage new content: text ]; andShow: [ :a :page | a custom: (GTPlayground new startOn: page) ]. ^ browser openOn: 'a := 42â. Does this help? Cheers, Doru > On Jan 16, 2016, at 6:24 PM, Offray Vladimir Luna CÃ¡rdenas <offray(a)riseup.net> wrote: > > Hi, > > I'm still kind of lost here. If I try with these approaches I get a *new* GTPlayground window populated with content, instead of an embedded one. How can I made this GTPlayPage one that is embedded in a spec glamour interface, like the one in the minimalist example: a dictionary with two keys/values: one which is shown as text and other that is shown as a playground, both populated with the content in the dict values and both, embedded in a widget instead of on separate windows.

Re: [Pharo-users] Pharo 5 new vm crash on window resize

by Ben Coman

I think logging every one-off non-reproducible bug leads to bug bankruptcy. Until there is a reproducible case, reporting here and waiting for similar reports from a few people or a more occurrences yourself is a good plan. cheers -ben On Sat, Jan 16, 2016 at 11:50 PM, Johan Fabry <jfabry(a)dcc.uchile.cl> wrote: > Hi all, > > this just happened to me: I opened a new image (todayâs build), resized it and the VM segfaulted.

Years ago I investigate this kind of problem for my application. I can't optimize PNGReader on image side. I tried to connect some C library but no success. My time was limited for this issue. And it was not really critical for me. So I gave up. After that Athens was announced. And as I understand Cairo can work with png-files directly without loading it to image side. I not try it. Maybe you can experiment with this.

how the bug report is bad ? No the workarounds were not helpful because I was already aware of them :) I appreciate people trying to help as always but yes it was upsetting to me , to be told that my bug report is bad, that loading 60 tiny images in 1 second is acceptable for a GUI and that opening 60 files is also near the limitation of my hardware. Because I find every one of them , very far from the truth and not very helpful. But I may have overacted also in my part so I apologize.

Re: [Pharo-users] Spec: Populating a playground with a particular content (was Re: Spec: Binding widgets how to)

Well thatâs actually much easier. :-) What you need to do is to use the presentationClass:startOn: API method. | ui | ui := GlamourPresentationModel new. ui presentationClass: GTPlayground startOn: (GTPlayPage new saveContent: '42'). ui openWithSpec I just realized that this was not clear from the examples in the class comment.
