Re: [Pharo-users] Scrollbar in Spec layout

by Johan Fabry

If I understand correctly, you are adding a lot of labels dynamically to the window, and you want a scrollbar to appear to the window, correct? I am afraid that this scenario is not supported by Spec. Instead you should use a list and add items there. Then you will get the scroll bar for free. Note that you can configure the list so that nothing can be selected, so the visual look will be more or less the same.

Re: [Pharo-users] Another question about Spec

by Johan Fabry

I donât know the details of drag and drop, but it seems that you get the source widget as well as an argument of the block. From there you can get the selectedItem, which should be the one that you are dragging I suppose. Can you confirm that this works? > On Feb 4, 2016, at 04:38, Julien Delplanque <julien(a)tamere.eu> wrote: > > Hey, > > I use drag and drop between two lists in a project and I read this tutorial [1] to learn how to do it. > > My question is: Is there a way to have another object than a String as passengers in #acceptDropBlock: (I get passengers the same way as in the tutorial i.e sending #passenger to transfer object) like the objects really in the list?

Re: [Pharo-users] Image Cleaner no longer useful?

by Marcus Denker

Hello, Sorry for the late answer. I think there are multiple problemsâ¦ 1) slowness. This is strange that unloading packages is so slow. This looks like a bug to me. 2) image size in Pharo5: We have a bug right now that images *never* shrink. This means that if you save an image once with 80MB, even if the GC cleans up, the saved image stays 80MB. We should fix bothâ¦. > On 25 Jan 2016, at 13:32, Maximiliano Tabacman via Pharo-users <pharo-users(a)lists.pharo.org> wrote: > > > From: Maximiliano Tabacman <mtabacman(a)yahoo.com> > Subject: Image Cleaner no longer useful? > Date: 25 January 2016 at 13:31:28 GMT+1 > To: "pharo-users(a)lists.pharo.org" <pharo-users(a)lists.pharo.org> > Reply-To: Maximiliano Tabacman <mtabacman(a)yahoo.com> > > > Hi, and sorry if this has already been discussed. > > In Pharo 3, I used to be able to do: > > ImageCleaner cleanUpForProduction > > and that would correctly remove a lot of unneeded code in the image when preparing for a productive release. > Then I would save the cleaned image, and since it had been cleaned, it would be smaller than the original development image (say from 60 mb to 25 mb). > This process would take about 2-3 minutes. > > Then, in Pharo 4 it seems some changes were made here, since the same process took a lot more, like 20 minutes. > > When I first tried Pharo 5, I was happy to see that it was again down to 2-3 minutes. > > And here comes my question... > Why is it that since some 2 months ago (maybe more), the Pharo 5 images once again require like 20 minutes to complete the cleanUpForProduction process? > > Also, and this is the most relevant to me, it no longer reduces the image size. > So if I want to release a Pharo 5 version based on the latest images, I would be shipping a product that is more than twice the size of previous public versions of my software! > > Thanks for any insights into this.
