Re: [Pharo-users] Timezone offset in Date, why?

by Sergio Fedi

I'm not sure how I would handle that, but I would take a look at Chalten/Aconcagua on how they do that. â

by Cyril Ferlicot

Hi Peter, for now Pillar doesn't manage this. I'll take a look at it when I'll work on the Beamer exporter.

RWView signalUpdate

by Lusa Nicolas

Hi, I noticed that with the recent changes that you made the view isn't updating anymore so I would like to update it by myself. I saw that in RWView there is the method called signalUpdate which is supposed to update the view but when I call it actually nothing happens. The situation that I have when I use it: - I have some objects in gray color displayed in my view. - I change the color and update the element. At this point the view doesn't update automatically so they stay gray even though I changed the color - I call signalUpdate on my view but nothing refreshes, the objects stay gray. At first I thought the problem was that the instance variable signalUpdateCallback was not initialised since in the initialisation is set to be nothing. But then I noticed it is actually initialised in RWViewWindow so that should be fine. I also have to say that my focus is not on the window that displays my objects but on another window in the same pharo image (just beside the window that contains the objects). Might that be the problem? Even though I have this situation I really would like to update the view even though the focus is not on that window. Any idea on how to make it work? Thanks Nicolas. P.S. any news on the possibility to distinguish different buttons interactions (i.e. distinguish left from right click of the mouse)?

Re: [Pharo-users] PUngLite can't query large database

by riverdusty

Hi Paul Yes, the query works on smaller databases. I've created quite a few, one of them was 200MB and that worked! I believe this is some memory/size limit. I'm curious if there is a suitable way to overcome/override this limit. I'm working on another project today but I'll try those suggestions perhaps later or tomorrow and get back with the results. Thanks for the reply and suggestions.
