[Pharo-users] World lastKeystroke and openInWorld: aPasteUpMorph

[Markus Schlager]

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 '<down>' 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?
