Pharo Launcher in Windows and Linux

by horrido

I've encountered some issues with Pharo Launcher in Windows and Linux. First, in Windows 7, upon starting Pharo Launcher, you get this: *primitive #createDirectory: in WindowsStore failed* If you push through and create an image and then try to launch the image, you get this: *primitive #primSize: in MultiByteFileSystem failed* Completely unusable. Second, in Linux (Manjaro), if you create an image for *Pharo 6.1 (stable)*, and then launch it, you get this: *FT2Error: Freetype2 primitive failed [error -1][can't get error string]* It seems to be usable, though. The issue does not occur with Pharo 6.0. All of this comes from the latest Pharo download at pharo.org/web/download. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: [Pharo-users] RTDoubleScrollBar is not rendered properly in html

by Andrei Stebakov

Alexandre, is there a way to display RTTreeLayout so that it would try to fit elements in a more vertical fashion. Let's say even if the parent node has 8 children it would try to arrange them not in one long horizontal line (which depending on the width of elements can be really wide), but spread them more vertically, so they would be viewable on one page. Or maybe I need to try another layout to reach that goal?

And these are not the same stateful traits.

not in 6.1 (and they will not be available ever, since is not a backportable thing). but you can use them in 7.0a :) Esteban > On 24 Mar 2018, at 10:22, HernÃ¡n Morales Durand <hernan.morales(a)gmail.com> wrote: > > Suddenly I need a stateful trait and had a quick look at this paper : > http://scg.unibe.ch/archive/papers/Verw11bFlexibleObjectLayouts.pdf > > Is this supported right now? > Any code example out there? > > Cheers, > > HernÃ¡n >
