If I try to bring up a viewer on a Transcript by clicking on the Blue Eye, I get a "message not understood: step". This fails in 3.0 and in 3.1 alpha.

Re: Help needed with morphic scripting
by Alan Kay 02 Mar '01

Hello again. This is a cute project, and would be fun for kids to do. If you'd like to get smooth plotting, go to the preference "Batch Pen Trails" and turn it on. This will amalgamate all location changes in a tick to a composite pen movement. Preferences can be found in the "Squeak" flap. Get it out and just type in "bat" and it will find the preference.

Well, kids aren't very good at that kind of thinking, so we didn't put in logical operators (we probably will at some point). They also aren't very good at nesting conditionals, but that is one way to get "OR". What they are surprisingly good at is to use parallel conditionals, either in a single method or even as concurrent methods, to pick out the "guard" for each case.

What Morph to Use?
by Dan Shafer 02 Mar '01

02 Mar '01

I thought it would be fun to see if I could create a counter with three buttons and a readout. (The one I used in my early Smalltalk books and that has been done and re-done lots of times.) But I wanted to see if I could do it entirely with direct manipulation of Morphs. The problem is I can't find a built-in Morph that displays a numeric value and understands how to add to and subtract from itself. I know how to do this with a bit of textual scripting using TextMorph or StringMorph but other promising-sounding Morphs (like the tantalizing UpdatingStringMorph) don't seem to work. I know I could create such a Morph and I will if that's the best way to approach this but I was sort of hoping to use this as a Tutorial and if the user has to build a new Morph as a part of the construction, it's not going to seem very entry-level. Thoughts? __________________________________________________ Do You Yahoo!? Get email at your own domain with Yahoo! Mail. http://personal.mail.yahoo.com/

Copying Morphs and global/local coordinates?
by Peter Munro 02 Mar '01

02 Mar '01

[VM: Squeak 3.0 (release build 1); Image: Squeak3.0final] I want a to copy a morph when I start dragging (a la Mac/Windoze Finder/Explorer). In my #startDrag:, I'm doing: event hand grabMorph: self veryDeepCopy If I drag a copy from within an AlignmentMorph, the new copy is attached to the HandMorph as I'd expect, with the cursor arrow tip directly on the morph.. But if I put the AlignmnentMorph in a ScrollPane, the new copy is dragged, but offset from HandMorph (ie cursor tip is far away from morph it is dragging). The offset appears to correspond to the offset of the ScrollPane from the top-left of the world. After inspecting I see that the ScrollPane and TransformMorph have bounds appropriate to their position within the world, and the AlignmentMorph has a topLeft of 0@0. So: 1. Am I creating a new copy of the morph in the right way? (Dragging the original works fine.) Should I be instantiating a new morph from scratch? 2. How do I get it to work?! 3. Which component should (really) be responsible for adjusting a morph's position when changing coordinate systems? Many thanks in advance! Cheers, Pete ---- Peter Munro
