RE: PPT presentation

Thanks David.  I just started experimenting with this approach.  I did
indeed get to the ThreadNavigator and somehow got projects loaded into it.
Note the lack of understanding in that statement.  Sorry to be so dense,
but:
Q1:  is a ThreadNavigator (TN) persistent; i.e., can I save it to disk as I
can projects?  (a 'no' answer to this will cause me to reconsider this
approach)
Q2: what are the exact steps for adding an *existing* project to a TN?
When I create a New project (that I eventually want added to a TN), it gives
me a clean world and I lose the TN.  I'm confused.

About the Book approach, thanks Kim for distinguishing the Book from the
Page.  That was not at all obvious to me and it helped a great deal.

If it responded to your hitting Esc, then it already failed, and the details 
would be in the previous (the real) project. So you hit Esc, then use the 
World menu that then appears to go to the previous project (the real project) 
and look for a debug notifier on the screen. Choose "save to log"; then send 
the SqueakDebug.log file that is created in the default directory to us.

Viewer in a Book's Page [was PPT presentation]

I'm now experimenting with using a Book to hold my presentation.  Overall,
I'm pretty happy with this approach.  (One caveat was that I couldn't
directly insert/open more than 1 image (jpg) into a Page - it would always
go into the entire Book; however, then I discovered the object's Menu
handle->"embed into..." ->Page and was happy again).  

Now I'm confused over my inability to have an object's Viewer appear only on
a particular Page and not the entire Book.  Strangely, I thought all was
well since I was flipping thru pages and the Viewer did indeed appear only
on the last page which was where I wanted it.  However, when I Published my
project and loaded it back in, that Viewer appears on every page.
Suggestions?

Sure. If you save a single project that has a Thread Navigator visible, then that navigator will be there
when you reload the project. Alternatively, you can save the whole image, thus saving all projects and all
threads at once.

1. If you are in the new project without a navigator, get one as you did before (supplies flap, new morph menu, whatever).
2. By default that navigator will contain all projects. Switch it to the thread you have been constructing
by clicking in the orange dot in the middle of the navigator to get a menu. In the first section of that menu,
there should be an item "switch to <whateverYouNamedYourThread>". Choose that item.
3. From the second section of that same menu choose "create thread of all projects". This will open a Project
Sorter containing all projects. Move it away from the center of the screen since we are going to open
another sorter and we'd like to be able to see both of them.
4. From the menu once more, choose "edit this thread". You now have a sorter for your thread. You can now drag
projects from the "all projects" sorter into your thread. You can drag projects within your thread to
reorder them and you can drag projects out of your thread so they are no longer part of the presentation.
5. When you have finished, click OK on your thread and confirm the name (or change it if you like). Click
Cancel on the "all projects" sorter since we were just using it for spare parts.

Cheers,
Bob

reflection symmetry

I'm attempting to perform a 2-D reflection symmetry on an object by doing a
left-right flip 180 degs - as depicted in the attached jpg (assuming it
comes across OK).  Basically what I've done is sketched 1/2 of a
(bilaterally symmetric) leaf, moved its rotation center to the axis of
reflection, and in a script:

  Sketch's rotationStyle - flip left right
  Sketch turn by 180

However, when I execute the script, the object gets flipped "in place",
about the center of the object (as if I'd never moved the rotation center),
rather than about the rotation center as I desired.  In fact, moving the
rotation center anywhere has no effect on the flip action.

Suggestions?

Re: reflection symmetry

Hi Randy --

I think this one is a bug (or in this case more accurately: an 
unimplemented feature). It should perform the way you want (and I think we 
should put in this feature). But there is a way to script in etoys what you 
are trying to do.

Cheers,

Alan

report bugs

Hi, where do I report bugs to the Squeakland Plugin image?

Changing system fonts for flaps freezes my whole squeak - to get Squeak
work I have to restart the VM....

I can reproduce the bugs for Linux (Suse 9.2) and Mac OS X Panther:
World Menu: appearance/system fonts/flaps fonts -> change to Bitstream
VeraSAns or *VeraSans Mono, try to make a new size (10 pt)...

best regards, Chris

At http://bugs.impara.de/ - switch to the "squeakland" project using 
the drop-down menu in the upper right corner.

Since 13 years, the European Smalltalk User Group (ESUG) organizes the
International Smalltalk Conference that aims at being a live forum on  
cutting edge
software technologies that attract during a whole week people from both
academia and industry. Every year about half of attendies are engineers
using Smalltalk in business while the rest of attendies are students and
teachers using Smalltalk for both their research and courses.

As for every year, this year edition of the event wil include the
regular technical program with high quality invited speakers. Besides,  
we'll
have a reseach track with an excellent program committee, a business day
about Smalltalk successfull use  in the market place, and a technology
awards where prizes will be distributed to authors of best pieces of
Smalltalk related software.

THIS  YEAR we are looking for YOUR EXPERIENCE Reports using smalltalk
so please come to tell us more on your experience and projects

Here is a non exhaustive list of topics we are interested in:
