Horizontal Wheel Events Broke Linux Word Jumping
by Sean P. DeNigris March 5, 2015

March 5, 2015

Apparently, Ctrl+left/rightArrow, which used to move to the previous/next word in an editor, now gets treated as a horizontal wheel event. The offending code is in #generateKeyboardEvent:, but I find it incomprehensible e.g. why is buttons bit shifted by 3? Why does Ctrl-leftArrow report different modifiers than Ctrl alone? Before I dig in, is anyone familiar with Morphic events that can take a quick peek? Thanks. p.s. I thought we had replaced the event buffers with real objects ----- Cheers, Sean -- View this message in context: http://forum.world.st/Horizontal-Wheel-Events-Broke-Linux-Word-Jumping-tp48… Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Example implementation of associations with Slots in Pharo 4.0
by Jan van de Sandt March 5, 2015

March 5, 2015

Today I experimented a little with the new Slots feature of Pharo 4.0. As an example I implemented support for associations/relationships. With it you can link two slots together so an update on one side will also update the other side of the association/relationship. I used these Movie and Person classes for testing: Object subclass: #SlotExampleMovie slots: { #name. #year. ToOneAssociationSlot named: #director target: #SlotExamplePerson inverse: #directedMovies. ToManyAssociationSlot named: #actors target: #SlotExamplePerson inverse: #actedInMovies } classVariables: { } category: 'SlotAssociations-Tests-Example' Object subclass: #SlotExamplePerson slots: { #name. ToManyAssociationSlot named: #directedMovies target: #SlotExampleMovie inverse: #director. ToManyAssociationSlot named: #actedInMovies target: #SlotExampleMovie inverse: #actors } classVariables: { } category: 'SlotAssociations-Tests-Example' With this definition the director of a Movie must be a Persion instance. When you set the director of a movie this movie is automatically added to the directedMovies collection of that person. Off course it also works the other way around. It took very little code to add these association slots. I think Slots are a really nice addition to Pharo!

Reading an SQL db on OS X
by Alexandre Bergel March 4, 2015

March 4, 2015

Hi! I would like to read a SQL .db file. The page http://smalltalkhub.com/#!/~PharoExtras/NBSQLite3 mention how to do this on Windows and Linux, but not on OSX. What should I do to read a SQL file on OS X? I tried google, but it did not work.

Missing Context Menu Hook
by Sean P. DeNigris March 4, 2015

March 4, 2015

The following was removed from Morph>>#mouseDown: evt yellowButtonPressed ifTrue: ["First check for option (menu) click" (self yellowButtonActivity: evt shiftPressed) ifTrue: [ ^ self ]]. in a commit by Guillermo Polito on 5/3/2013 (integrated between #30084 and #30351). Can we add it back? Right now there seems to be no hook for context menus, forcing users to dig through Morphic and roll their own. ----- Cheers, Sean -- View this message in context: http://forum.world.st/Missing-Context-Menu-Hook-tp4809492.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.
