Hi,

Umm... I still don't get it. Seems that the proper way to group objects
together is not by Composite shapes but with RTGroup and RTNest.
Hopefully with the time I will. Anyway I hope this question can help to
improve documentation.
Now, with some tweaks on the view, I'm capable of getting something like
this:
Which is pretty close to what we originally planed. I would like to play
with some color saturation on the epicycle, which could imply, at some
point changing the color of the font of the numbers on it, changing from
black to other colors. I also presume that would be nice to have some
kind of scale in the graph. Distance between epycicle and nucleus avatar
is measured in a logarithmic inspired scale, first days (green), then
weeks (orange), then months (red) and finally years (black).
So, two more questions:
- How can I select the zoom out level of the view, making all object to
fit in that view automatically (the screenshot was obtained by manually
zooming out and arranging the visual objects).
- How can I get this kind of "logarithmic" scale a rule in the bottom of
the view.
I remember reading something about factory of objects in the book Squeak
Learn programming with Robots, but that was the name for a class...
still I don't get it :-/
- Why composite shape was not the right thing to use and how can a
newbie could differenciate which strategy to use?
I think that the problem is the lack of good documentation. With all
this time, I am convinced that composite shapes are good at naming
elements. E.g., putting a name on top of circle or a square.
As soon as you want to glue two or more object
- A sytle
question "labeledCircleSized: upLabel: downLabel: at:"
seems descriptive to me, but I don't know if has the proper style for
a method name. I can read Smalltalk with Style to look at it, now
that I know more about the environment, but advice of seasoned
smalltalkers would help a lot in getting proper style also.
You may want to use a factory object to configure its creation :-)
Will you be at Esug by the way? We will have a camp about Roassal.
Unfortunately I will not (long distance between Colombia and Europe),
but hopefully I will find the way to visit Chile :-).
Cheers,
