Another Halo Question (complete newbie)

How-dee!

I'm working my way through PBE (no, I've been too broke lately to buy
a copy yet *blush*, but I will) and a few other smalltalk tutorials.

I've read the documents about getting halos activated in the first
place. I'm on linux, where alt-shift middle-click (I'm still trying to
get the button colors down) generally works.

In the lights out sample, it doesn't. I can ctrl-shift "left" click,
get a giant menu, and select "Add Halo." That puts a halo around the
individual cell. If I close it, it disappears and shows a blue
background (which I'm starting to suspect is a default for
morphics...is that close?).

If I jump back through the "Add Halo" hoops on that background, or
actually manage to click on the border, I just get what seems to be
halos for the desktop (system? background? It's always frustrating to
start learning a new system and not know the terminology...then again,
that's part of the fun).

I've been able to close the morphic by adding a "self owner delete"
mouse down handler to the cells, then commenting it out until I need
it. But it's more than a little painful.

I spent about two hours today googling for variations on "morphics
decorated frames", but the results I got suggested that I'm not even
in the ballpark.

I'm sorry if I missed an FAQ or didn't dig far enough back in the
mailing list archives.

Thanks in advance,
James

there is no problem. The pdfs version is for that :)

Strange I do not get it.
normally the halso should be displayed when you click and option shift (but I'm on mac)

I'm going through the book too. If your problem is that you can't close the game then here's how... First, get halos around the upper-left cell and close it; it should turn blue. Then get halos around the cell that turned blue (which should be labeled 'LOGame') and then you can close the game. Hope that helps, Dan

To close all the games opened you can evaluate:

That's where my problem is...when I try to get halos around the closed
cell, it skips the LOGame morph and puts them on the desktop instead.
There's no 'x for close' option.

It tells me that I was on the right track. Maybe I need to just break
down and try the latest development version.

Thanks,
James

I haven't had a chance to test it out, but that's pretty much exactly
what I was looking for.

It was great, and helped a lot of pieces fall into place for me.

OK, cool. That makes me feel a lot safer about my suspicions. So I'll
keep doing what I can to learn, and contribute back if I actually get
that far.

Is there some sort of reference about why the fork was made? I'm sure
there were a lot of politics (icck) involved), and pharo feels a lot
more solid than squeak ever did, but I'm curious about the real
reasons. The website's "we felt the project was moving in the wrong
direction" just implies a lot without really saying anything.

I don't want to dig skeletons out of the closet or bring up any old
hard feelings. I'm just curious.

Thank you,
James
