How to send messages to an object.

by nacho

Hi, Suppose I do: Morph new openInWorld and then: EllipseMorph new openInWorld without referencing them to a variable. How do I access those objects? Since the only thing I know is that is a "a Morph(428605440)" and a "an EllipseMorph(448004096)" If I want to Morph(428605440) addMorph: EllipseMorph(448004096) How do I achieve this? Because they are both object living in the system but I can not reference them..... Thanks in advance Nacho ----- Nacho Smalltalker apprentice.

Re: [Pharo-users] Spotter: How to see more beyond #/##

by Tudor Girba

Hi Stef, I think we are misunderstanding our terms :) Let's take an example: When you have the default Spotter, don't you feel like clicking on the triangle that goes outside of the normal bounds of the window? And once you do that, does that not teach you about a new functionality without any manual? It did so with all people I tried it on. That is what I mean by having visual representations for actions. Ideally, everything that is possible should also have a visible aspect to it that should guide as a teacher. Right now, we do not do a good job at teaching shortcuts, and this will be improved.

Re: [Pharo-users] Spotter: How to see more beyond #/##

by Johan Fabry

+1 on what Stef said. And for what itâs worth, I think that the biggest step to add usability of the spotter right now would be a simple legend at the bottom of the results. It would list the shortcut keys applicable to the current selection with a small description of what they do. Itâs not sexy and exiting to implement but it will be a huge help. For example, such a legend would have eliminated all the questions and conversations on the spotter that happened this week. > On Feb 7, 2015, at 15:50, stepharo <stepharo(a)free.fr> wrote: > > > Le 5/2/15 14:38, Tudor Girba a Ã©crit : >> Hi, >> >> Yes.

DateAndTime>>fromJavaScriptTime:

by Sebastian Sastre

Hi guys, When you have a JavaScript date number like: new Date(1412279266711) for Thu Oct 02 2014 16:47:46 GMT-0300 (BRT) It would be really great to be able to do in Pharo something like: DateAndTime fromJavaScriptTime: 1412279266711 Do we have something that can do that?

Re: [Pharo-users] Image growing size

by Laura Risani

Problemution (problem+solution) found! I've tried clearing package cache, image cleanup -> size decreased a little. unloading all my packages -> size unchanged. Yet i haven't thought as my doing about TilingWindowManager i've installed! It has an option for snapshooting worlds, it's possible i've been triggering it involuntarily with some shortcut i wasn't aware of, anyway if this was the case i get no visual notification when snapshooting (like the one you get when saving the image). disabled TilingWindowManager -> size decreased about 200 MB, down to 20 MB. Also the discussion brought up very interesting msg collaborations snippets and system features for future reference!
