Re: My First Doc Contribution

Mark Guzdial's book has a good section on the debugger. Worth buying for lots
of other stuff, too.

[FIX] Bug in package browser (fwd)

I still get that at update #3910, too.

so, here's the fix, packaged as a cs this time.

from the preamble:

"Change Set:		BrowserSystemCategoryList
Date:			30 April 2001
Author:			Joern Eyrich

fixes a problem reported by Scott A Crosby when adding a Category in the Package Browser without having a
Category selected.
changes hardcoded access to category list to use subclass-overridable access method"

The project itself doesn't require the net at all.

As far as project loading and the net, Bob or Andreas could answer this 
better.

I asked recently about whether it would be possible to use the .pr files 
without net access. Andreas said it would be; if your system isn't working 
right, it might be useful to find out why.

Andreas answered:

Yes, absolutely. That's the entire point of the exercise. The data included
in a project published to your local disk is complete to prevent that sort
of problem that you have when trying to send around HTML files.

Ned....

::Sound of open hand smiting forehead::

How could I have missed that?! Wow. I'm off to change the tutorial. This makes
it much easier to explain. I can get into IVs later.

Thanks!

[FIX] fix for currentWorld getting set to BookMorph pages

I think I figured out why currentWorld was getting set to
BookMorph pages. I changed the condition in
PasteUpMorph>>processEvent:using:

from preamble:

"Change Set:		ActiveWorldFix-nk
Date:			5 April 2001
Author:			Ned Konz

This fixes the problem with non-World PasteUpMorphs setting
ActiveWorld when handling an event."!

Thanks Dan

I got it going after about 3 hours (the first direct manipulation morph
I've done, and only the second morph).

I'm not entirely sure, but I think most of the problems I had with it
were either down to my using 2.8 (it's written for 3.0) (can anyone
comment? has Morphic been improved in 3.0?) -- I found duplicating the
buttons easy enough, but all kinds of wierd stuff seemed to happen when
I tried to duplicate the scripts -- either the messages would appear
disconnected or to conflict, or by following some of your more
experimental suggestions and finding I had no idea of how to get back
other than exiting and going back to the last save. 

Not that the experimental or "oh, wow!" stuff isn't really important,
but maybe it belongs in a box out or a footnote as it's pretty tricky to
follow a textual description of drag and drop programming at the best of
times.

This morphic by direct manipulation stuff looks tremendously powerful
and it's great to think it'll be documented more.

May the morph be with you!

No, I was saying that you don't have to add an instance var at all. You can 
use the text category of the viewer to access the text contents directly as a 
number. No typing of code:

*make a new textmorph
* bring up its viewer
* select the "text" category in the viewer
* pull the green/purple arrow to the right of "numeric value"
* roll the up/down to the left of "numeric value" till it reads "numeric 
value increase by"
* change the 0 to a 1

done!

Re: Squeak Port to HP Jornada 720

Yoshiki Ohshima (Yoshiki.Ohshima <at> disney.com) has a WinCE VM for StrongARM
that works on the iPaq. It would probably work on the Jornada 720, too. I think
it's pretty much just the stand WinCE sources compiled for StrongARM.
