So we wrote it, rewrote it, rerewrote it. Now if this is of interest for you you can read it. But if you don't it means that I'm losing my time and I should stop writing and like that you can cry that there is no doc about Pharo. Stef -- Mariano http://marianopeck.wordpress.com

creating a Rectangle

by Andre Hora

Hello, To create a Rectangle in Pharo with the method Rectangle>>origin:corner:, you must provide the top left and the bottom right points. With others you have a Rectangle with area equals to zero. I just noticed that in VW it is possible create a Rectangle with other points (bottom right and top left, bottom left and top right, ...). So, shouldn't Pharo Rectangle allow the same? regards, -- Andre Hora

I remember this now. This is a good bit of documentation, thanks. I don't know if it may need changes for 1.2.1 images though. Thanks, Tim

Hi Lukas & Marcus, Thanks for the tips. - In the One-click 1.1.1 image (CogVM) from the Pharo homepage, this preference is not present. - In the One-click 1.1.1 image (non-Cog) it is also not present. - In the Seaside 3.0.4 One-click image* (seaside.st) [this is the one originally trying my patience], turning off System Settings->Code browsing->eCompletion (yes, the parent item) does not make the extraneous ' go away. Seems as if it does not disable the children items (in fact it makes the children & disclosure triangle disappear). Re-enabling it (so its children re-appear) and then individually disabling "Smart Characters" does indeed work. - In the 1.2.1 image* this preference does work! :D Thanks again, Tim * in the Browser, I had to highlight a class category before I got "add category..." on my right-button menu
