[Pharo-users] World lastKeystroke and openInWorld: aPasteUpMorph
Hi, I'm using pharo to teach smalltalk as first 'real' programming language at school. With older versions of pharo I was glad that my pupils could track keystrokes so easily by evaluating World lastKeystroke. With Pharo3.0/4.0 this only returns '' independently of any keys I'm typing. f := PasteUpMorph new openInWorld. f takeKeyBoardFocus. f lastKeystroke. Is returning the empty string. Hence, my question: Is lastKeystroke broken, or how is it meant to be used now? Second problem: In older versions of pharo this would work: f := PasteUpMorph new openInWorld. b := EllipseMorph new. b openInWorld: f. But with Pharo 3.0/4.0 the last line raises an error: MessageNotUnderstood: PasteUpMorph>>startSteppingSubmorphsOf With f := WorldMorph new openInWorld. b := EllipseMorph new. b openInWorld: f. pharo freezes. So: How is openInWorld: meant to be used? Markus

"integer" keyName := anEvent keyString. "string like '' or 'a'" ... m := MyMorph new. m takeKeyboardFocus. ---8X- Markus

Re: [Pharo-users] Morph relative positions
I'd not expect though, that it should be necessary to add offsets by hand. What is the advantage of having embedded objects use global coordinates? Markus
Re: [Pharo-users] Morph relative positions
On Fri, 20 Sep 2013, Norbert Hartl wrote: Next try. I may do something stupid but it appears that all morphs draw on the same coordinate system. Meaning that every Morph that will draw something at 0@0 will put it in the top left corner of the image displayed. I would expect that a morph that is positioned somewhere provides a canvas where 0@0 is relative to the position of the morph. If coordinates are absoulte how can I delegate work to sub components and having them calculate the offsets properly? I had this problem to while teaching pupils (grade 10) Smalltalk as their first 'real' programming language. We were embedding EllipseMorphs into a PasteUpMorph. Embedded morphs know their owner, hence self owner position might be the desired offset. Markus

I use Etoys or Scratch in grade 7 (age about 12 years) and Smalltalk in grade 10 (age about 15/16 years). They are attending regular "Informatik"-courses at Gymnasium, supposed to learn object-oriented modeling and programming. Markus
Re: [Pharo-users] seeking your tutorials
Hi Martin, Some material (in German) I use at school (10th Grade, Gymnasium). The Prof-Stef-Tutorial is about pong, developed with pharo 1.3, I guess, but changed a little for pharo 3.0. http://www.gymnasium-untergriesbach.de/system/files/oeffentlich/unterrichtsmaterial/informatik/10.klasse/skript/sr/info10-oop-folien-schlager.pdf contains an older Squeak-related tutorial of mine and a "Taxi"-Tutorial I did with Java first (I had to use Java) and later with pharo to have a comparison. A short handout I give to my pupils: http://www.gymnasium-untergriesbach.de/system/files/oeffentlich/unterrichtsmaterial/informatik/10.klasse/sonstiges/sr/smalltalk-werkzeugkiste_2.pdf There's also a similar Java-Werkzeugkiste on this website covering the same stuff but significantly longer Markus MS-info10-ProfStef-MarkusSchlager.20.mcz Description: Zip archive
