Sean I agree that TDD would really make sure that we can script such object. I do not know how to motivate people to do so. In bloc I started to write tests and I immediately found bugs. So it was positive and may be we should have a group of people writing tests. Now I have to finish the mooc and I was waiting that bloc stabilise again. Because I spent time writing comments and they are probably wrong now especially since writing comments on thing you do not master is a PAIN. Stef

Re: [Pharo-users] Getting whether specific key is currently pressed

by Jan BlizniÄenko

Ok ok, you all have convinced me that this should be solved on Roassal part, not by calling such low level stuff like Sensor. I'll try to make and propose some changes in Roassal to forward such information. And, Alex, my case is that when I just drag box around items on cavas (do marquee selection), all previously selected items are deselected and there is new selection made, but if I have shift pressed while doing it, these new selected items are ADDED to previous selection. I wanted it to be control instead of shift, but it seems control+left mouse button=right mouse button (don't know why, what a waste of ctrl, maybe for compatibility with some OS unknown to me (OS X?) or some old OS - like I've seen there are parts of Pharo where mouse buttons are called blue, yellow and red :) ). I created my own subclass of RTAbstractElasticBoxInteraction for that job and this RTAbstractElasticBoxInteraction also needs to be modified to forward such "...KeyPressed" info. I didn't use RTSelectableView, because I do not want to select each Roassal element separatedly, but I need to select only our DynaCASE "elements" which may consist of multiple Roassal elements.

Re: [Pharo-users] Bloc Space within a Space

But I thought that space/universe was done so that we could build multidesktop with mini space to select where to jump and we can imagine that such mini space would be running. So what sean wants to do should be possible. At least I thought that alain planed it. stef Le 14/2/16 16:51, Aliaksei Syrel a Ã©crit : > I'm not sure I understand what you want to archive with provided code :) > Space is not something you want to embed in another space.

Bloc Alarms: Why Raw Numbers Instead of Domain Objects?

by Sean P. DeNigris

"scheduleIn: 10000" seems much more awkward than "scheduleIn: 10 seconds", and #scheduleAt: is even clunkier - timeInMs - what's that? Unix time? Squeak time? Wherease "#scheduleAt: '3/1/2016 6:55pm' asDateAndTime" is perfectly clear ----- Cheers, Sean -- View this message in context: http://forum.world.st/Bloc-Alarms-Why-Raw-Numbers-Instead-of-Domain-Objects… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Yes, this is what I am disappointed before. Of course that makes sense in practice in the normal operation of the system, but limits one's creativity to pre-approved uses. IMHO this is the kind of coding-for-one-world-view that made Morphic infuriating to really try to reinvent. Aliaksei Syrel wrote > You can create a separate 'Bloc-Test' space and do testing there. I should have been more specific. Yes, one can do functional testing, but one can not stub out the dependencies and unit test properly. In fact, IMHO this area of the design is a symptom of lack of TDD. ----- Cheers, Sean -- View this message in context: http://forum.world.st/Bloc-Space-within-a-Space-tp4877474p4877492.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

I'm not sure I understand what you want to archive with provided code :) Space is not something you want to embed in another space. Space manages UI thread, event fetching, alarms and many other low level stuff. Universe contains spaces and there can be only one running space at a time - read there can be only one active UI thread and event fetcher in the system. Check Bloc-Core-Universe. Alain put a lot of effort writing class docs. Please, could you explain in more detail your idea and provide some examples where embedding of spaces could be applicable? This makes real testing possible, prevents another global > mess, and makes other /really/ exciting possibilities within reach Why?

Bloc Space within a Space

by Sean P. DeNigris

I always wanted to do this in Morphic, but it made too many assumptions about the World's environment e.g. use of globals like ActiveHand and World. I gave it a shot (see below). The new space did appear in the current world, but the rectangle seemed to open in the container world, not in the new world because when I closed the new space via the halo the rectangle remained. For me, it is very important to have a space easily create-able and drivable. This makes real testing possible, prevents another global mess, and makes other /really/ exciting possibilities within reach. Can it be done in Bloc? If not, what would it take? s := BlBlocSpace new. root := s rootElement. root extent: 500 @ 500. root openInWorld; yourself. rect := BlElement exampleRectangle. rect openInWorld: root world. s redraw. root updateDrawing. ----- Cheers, Sean -- View this message in context: http://forum.world.st/Bloc-Space-within-a-Space-tp4877474.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
