Ok, I'm a bit behind in my email but I would help mentor if need be. Just to ensure it works ok on os-x and also to ensure support for objective-c creeps in there somehow since Apple's direction is towards everything in Objective-C frameworks versus "C" library calls.

[Pharo-project] Paint gradients rectangles on #onDraw: method
by nullPointer March 10, 2010

March 10, 2010

Well, IÂ´m continue working on a Grid widget. My old grid was very slow in load data. I changed the old mechanism of columns and rows ( each row was a panel with cells in tableLayout ) by #onDraw: mechanism, painting the cells and contents of it. Now is incredible much more faster. I believe than another people with more knowledge could do more fast too. Now my next problem is implement the "styles" of widget. I need paint gradient rectangles, for color of rows , alternate rows, cells etc. Is possible do that with #onDraw: mechanism? exists some previous example? Many thanks for the answer; regards. -- View this message in context: http://n4.nabble.com/Paint-gradients-rectangles-on-onDraw-method-tp1587597p… Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] [update 1.1] #11255
by StÃ©phane Ducasse March 10, 2010

March 10, 2010

11255 ----- - added tests for the compiler to test shadowing of self, super, thisContext, true, false and nil. Thanks guys - we know you :) - Issue 2086: Introduce a cleanUp/cleanUp: protocol from squeak / keith idea! MyClass class>>cleanUp: aggressive This (class-side) method is called with an argument that indicates whether to do aggressive, i.e., potentially destructive cleanup. Doing aggressive cleanup will delete projects, change sets, uni-classes and more. Gentle cleanup is expected to only flush transient caches. If your class only has gentle cleanup you can simply implement MyClass class>>cleanUp By default #cleanUp: delegates to this method (similar to startUp/startUp: and shutDown/shutDown:). You can run cleanup by executing: Smalltalk cleanUp. Smalltalk cleanUp: true. Thanks luc for your analysis. After lunch in hot room is never that good for my brain :) Stef

This sounds REALLY greate. PLEASE take a look to http://gsoc2010.esug.org/application.html the answer to point 2).

Hi guys Some good news :) INRIA-lille nord Europe ranked Pharo among the top 3 projects that will receive support for a full time confirmed engineer. We will know if the national level or the lab will carry the cost by mid april, but for now the position is allocated to Pharo. This is not the official job announce but just to give some hints and that you can prepare yourself to - move to France (one hour from paris, 1h30 from London, 35 min from Brussels) - try a lot of good beers (belgium :) - eat french food - have fun with us - yes we are even fun - ok with geeky humor :) - code all the day in Smalltalk and a bit of C Apparently from what the DHR services told me, the salary will depend on years of expertise and diplomas but we can think that 2700 Euros (before final taxes) should be a good working number -- In France the employer pays already taxes so the salary is not brutto but already includes deduction. The social insurance is included and you may want to pay an extra like me (100 Euros) to have a better health insurance. Lille is an active city but not expensive. To give an idea Marcus got a nice sunny close to everything flat with wooden floor for 650 Euros. The job will to continue making Pharo (core) better - better tools - better network support - helping with the new compiler - helping with alien and others - cleaning/shrinking Duration: 30 months Starting date: October 2010 Location: Lille (no remote job possible) Do not hesitate to contact us.

[Pharo-project] Something I don't understand with ImageSegments
by Mariano Martinez Peck March 10, 2010

March 10, 2010

Hi guys: I have this little (piece) of test: | segment external internal root | external := 'mariano'. internal := true -> external. root := false -> internal. internal := nil. segment := ImageSegment new copyFromRoots: (Array with: root with: external) sizeHint: 5000 areUnique: true. self assert: segment outPointers size = 2. And that is green. However, if I change 'mariano' to Object new, I have that segment outPointers size is 3 instead of 2. I really don't understand why. Does someone see something ? Thanks Mariano
