Why does the following leave anything in the list 'a'? Run it in a workspace. With or without the shallowCopy, i am left with a list with half of the elements in it.

Roassal question
by Werner Kassens Feb. 24, 2015

Feb. 24, 2015

Hi, i have a little problem, where i think roassal could perhaps be helpfull, but i have to admit this is the very first time i looked into roassal, hence i have a stupid question: i have a collection of something like rectangles, lets say: coll:=Array with: (Rectangle origin: 500@500 corner: 510@520) with: (Rectangle origin: 505@504 corner: 511@522). now i want to produce a graph that shows these rectangles together with the x & y axis that show their positions (in a sensible way). any simple hints how i could go about this task? werner

Conditional CSV parsing
by HernÃ¡n Morales Durand Feb. 23, 2015

Feb. 23, 2015

I used to use a CSV parser from Squeak where I could attach conditional iterations: csvParser rowsSkipFirst: 2 do: [: row | " some action ignoring first 2 fields on each row " ]. csvParser rowsSkipLast: 2 do: [: row | " some action ignoring last 2 fields on each row " ]. csvParser rowsWhere: [ " a condition block " ] do: [ : row | " ... " ]. csvParser rowsUpTo: 500000 do: [ " some action for rows up to 500000 " ]. csvParser rowsFrom: 2000 to: 5000 do: [ " some action for rows between 2000 to 5000 " ]. I want to replace the parser with NeoCSVReader, is this easily possible with the current implementation? Cheers, HernÃ¡n

MouseWheelEvent direction in Pharo 4
by Jan B. Feb. 22, 2015

Feb. 22, 2015

Hello In latest builds of Pharo 4 (in last 2 months probably), there has been a change in settings of mouse wheel event creation. In HandMorph >>#generateKeyboardEvent: In Pharo 3 there is MouseWheelEvent created by calling MouseWheelEvent new setType: #mouseWheel position: lastMouseEvent cursorPoint direction: (charCode = 30 ifTrue: [#up] ifFalse: [#down]) buttons: buttons hand: self stamp: stamp In latest Pharo 4 image, there is MouseWheelEvent created by calling MouseWheelEvent fromCharacter: charCode asCharacter position: lastMouseEvent cursorPoint buttons: buttons hand: self stamp: stamp There is a difference in what it results into, especially in MouseWheelEvent's instance variable direction. Pharo 3 sets direction to #up, Pharo 4 sets it to Character arrowUp. My question is whether direction being Character arrowUp is bug or feature, therefore if it should be fixed on Pharo side by using #up direction in MouseWheelEvent like before, or if it should be fixed on users side (Roassal for example), which currently compare it to symbol #up and should all compare it to Character arrowUp from now on.
