Re: [Pharo-project] Conflict between RPackage: ClassDescription >> package and BogusInfo class >> package

by StÃ©phane Ducasse

This is a mock class for Monticello tests may be we should rename it mcPackage but this will not be easy because mc will probably use it. Temporary we could rename RPackage one rPackage. > Hello, > I'm currently testing RPackage.

[Pharo-project] Conflict between RPackage: ClassDescription >> package and BogusInfo class >> package

by Cyrille Delaunay

Hello, I'm currently testing RPackage. RPackage define the method 'package' in ClassDescription. In my image there's only one class that already define this method, it's BogusInfo. I don't know what is this class and what would be the best solution to solve this conflict

[Pharo-project] Strange graphics effect (getting Pharo running on the RoarVM)

by Stefan Marr

Hi: When I run Pharo on the RoarVM, I have some strange graphics effects. Maybe anyone has seen something similar in the past and could point me in the direction of the problem. The attached screenshot shows the effect I see while moving a window. All parts of the window, which were containing text are basically cut out, and the other windows in the back are visible instead. This effects seems to occur only while dragging/moving the window. As a reminder, we are using X11. So, if anyone remembers to have experiences something similar in the past, please let me know what the fix was.

Re: [Pharo-project] About SimpleMorphic

by Fernando Olivero

Hi Juan, i have a couple of questions regarding the new Cuis layout, which by the way , is a much cleaner implementation!. "LayoutSpecs are the basis for a new layout mechanism, alternative to LayoutFrame. Any Morph can be given a LayoutSpec, but in order to honor it, the morph must be submorph of a LayoutMorph." In my opinion, we dont need to enforce the LayoutMorph subclasification. Because Morph>>doLayoutIfNeeded could use its "layoutMorphSpec" collaborator, if present. doLayoutIfNeeded ... [self layoutSpec layoutSubmorphsIn: self layoutBounds] on: Error do: [ :ex | ... What do you think? Fernando pd: Similar to decoupling the "visual layout properties" that Brazil is doing.

Hi Guido, We wrote a profiler to keep track of memory consumption. http://bergel.eu/download/papers/Berg10g-MemoryProfiling.pdf It will be presented at Smalltalks next week.
