animation, holder
by Randy Heiland 14 Feb '05

14 Feb '05

Hi Squeakers! I just went to Squeakland, downloaded updates, and was experimenting with creating a simple animation - per the "Powerful Ideas..." book and Squeakfest tutorial. It seems there is no longer a "Holder's playerAtCursor" tile in a Holder's viewer. Is that true? What do I do? I was pleased to see that dropping frames into the Holder is no longer plagued with the annoying problem of having to put the cursor in "just the right position". In fact, it seems that the behavior of a Holder is more dynamic than what I remember from Squeakfest, in that it resizes according to how many frames you drop in and allows for easy rearranging of frames - or maybe those features were already there and I didn't realize it. Although I didn't really push it, I'm wondering, if I drop in so many frames that the Holder exceeds the size of my world/screen, will the Holder automatically reveal scrollbars? (It would be nice :) Thanks, Randy

RE: [Squeakland] merging projects

Hi, An other way to put an objetct in an other project, dicovered by a student, is to drop this object on the Button representing the second project. You see the words 'I got it'. Then wait until the droped object comes back at his place. Go to your second project (by clic on the button) and you'll find the droped object in it. The complete process is: - load project 1 - From project 1, load project 2 - Go back ti project 1 (button previous in the navigator flap) - Now you can put any object of project 1 on the button for project 2. - Go to project 2 by click on the same button. - In project 2 you have now all the objects sent form project 1.

Thanks for the note, Kim. When I say it "got gridded" (sorry for the non-technical language), I mean that it instantly hung: the grid appeared, the progress bar never showed up, and I lost control of the window by any means other than hitting ESC. I couldn't click on anything at that point, or any point thereafter. I have discovered that (usually) if I choose "Publish As", all will work as you describe, except for the incident today. It may be that I am a relative newbie to Squeak, but I think it's got so much potential that I really want to make it work. I'm using it in my grade 6 computers class, and in my grade 7 programming class with slightly different emphases. I love the concrete nature of it for teaching programming. Is the debug file a separate file? Is that saved in the same folder as the .pr file? I know that I can get info when I try to debug using the ESC button, but that has several different views and doesn't seem to be an actual file I can send. Thanks, Bob Irving >>> Kim Rose <kim.rose(a)squeakland.org> 1/31/2005 5:47:08 PM >>> Hi, Bob - When you say "it got gridded" do you mean did it totally hang up? You are probably aware, but every project when 'publishing" will show the "grid overlay" at first. This then prompts a progress bar that changes color as the individual objects are saved. When the cycle has successfully completed, the progress bar and grid disappear leaving the (now published) project on your screen and the .pr file in your desired folder. I am guessing you mean the project froze or hung in the process while watching the progress bar...??? Please do send your debug file to Mike Rueger -- address above and copied of this mail. THanks! You might also want to send him the project you are having trouble publishing, too. sorry for these hassles!

Well, I thought I had it solved: hold the click on Publish It, and wait for the menu of options, then choose Publish As, and choose User (which puts it in My Documents in XP). A bit awkward, but workable. Except today, I tried that and it gridded as soon as I clicked on Publish It, while I was demonstrating to a student on how to save his project. Unfortunately, I said something I shouldn't have said in front of a student! Be that as it may, I would like to submit my debug info somewhere. How and where should I send it?

Hi, If you are navigating between projects, you must record the whole image, which is a lot of space. If yo are using a book , you just need to record the project containing the book. With a book, You can put in a page anything you can drop in the world. You can load this presentation and use it as template changlng the texts and deleting what you want. a click on a light blue rectangle show the text another click will hide it. a click on a light blue rectangle show the text another click hide it for plugin 3.8 http://p7app.geneve.ch:8090/squeak/uploads/1/demo_berne_new.pr for squeak 3.6 or 3.7 http://p7app.geneve.ch:8090/squeak/uploads/1/demo_berne.pr best regards -----Message d'origine----- De: squeakland-bounces(a)squeakland.org A: Randy Heiland Cc: squeakland.org mailing list Date: 28.01.05 11:11 Objet: Re: [Squeakland] PPT presentation Am 27.01.2005 um 11:17 schrieb Randy Heiland: > Hi Squeakers, > > I want to do a Powerpoint-like presentation in Squeak. I am doing the following: I make a new project for each slide. (The best is to make a template project, save that on disc and then load a new one for each slide). Then there is a morph calles "ThreadNavigator". This can be used to put together a presentation and then navigate through it. A bit hard to explain... we should make videos showing this kind of stuff.

Mozilla Plugin and Debian (Linux)
by JP Glutting 30 Jan '05

30 Jan '05

I am still trying to get the Squeak plugin to work in Debian. I have version 3.6-3 installed (from .debs), and the desktop environment works fine. I downloaded a npsqueak-image installer, and went through the install script to find out what to do. It seems that there is a script in /usr/lib/squeak called npsqueakregister that needs to be run. (the install script actually was looking in /usr/local/lib/, but the .debs put squeak in /usr/lib, which should be fine). The npsqueakregister script looks for /usr/lib/squeak/3.6-3/npsqueak.so, which I have. The script, when run, gives this message: File not found: /usr/lib/squeak/3.6-3/npsqueak.so Aborting. It seems that the permissions on npsqueak.so are not set correctly. It is set with permissions 644 [rw-r--r--], when the file needs to be executable. The npsqueakregister script is actually checking to see if npsqueak.so is an executable file (if [ ! -x "$NPSQUEAK_SO" ] ), and exits with an error message if it is not. I changed the permissions on npsqueak.so [chmod a+x npqueak.so] The npsqueakregister script then produces: Registering /usr/lib/mozilla/plugins/npsqueak.so create symbolic link `/usr/lib/mozilla/plugins/npsqueak.so' to `/usr/lib/squeak/3.6-3/npsqueak.so' Registering /usr/lib/mozilla-firefox/plugins/npsqueak.so create symbolic link `/usr/lib/mozilla-firefox/plugins/npsqueak.so' to `/usr/lib/squeak/3.6-3/npsqueak.so' Registering /usr/lib/mozilla-snapshot/plugins/npsqueak.so create symbolic link `/usr/lib/mozilla-snapshot/plugins/npsqueak.so' to `/usr/lib/squeak/3.6-3/npsqueak.so' Which looks great. However, I still can't run any .pr files in the browser. I just get a blank, white page, with the message "Done" in the status bar. This is what happened with OS X when the plugin was not working as well. On the positive side, Squeak is registered as a plugin (it registers sts, sqo and pr files, while OS X only only registers sts and pr files). I am going to keep twiddling with this, and try to figure out what went wrong. Any suggestions welcome. Thanks to everyone for their help so far!

PPT presentation

Hi Squeakers, I want to do a Powerpoint-like presentation in Squeak. That is to say, I want to do a multi-"page" presentation, where I have a few simple concepts (with large-font text + graphics) on each page. What is the best way to do this in Squeak? I thought it would be nice to use the Navigator's Prev/Next buttons to let me step through my presentation ("pages"). However, this would of course mean that each page is a project, which seems strange - unless there's some concept of a "parent" project that could serve as a way of letting me step thru children. I know there is a 'Book' in the Supplies tab. However, unless I'm missing something, a Book doesn't let me draw graphics into its pages. Anyway, I welcome your suggestions. --Randy

confusion over updates - solved, sorta
by Randy Heiland 26 Jan '05

26 Jan '05

After sending out my previous long-winded email, I then decided to get Squeak updates from sqeakland.org ("Get Squeak Updates!"), instead of doing the Esc->help route inside a running Squeak session. Doing it this way does indeed seem to update my Squeak executable. --Randy

Mozilla Plugin - Thanks!
by JP Glutting 26 Jan '05

John and Ned, Thank you both very much for the wonderful, detailed messages. I have the Squeak plugin working correctly on OS X now (I am going to go try Debian now). It seems I had version 3.7.5-beta installed. Not sure if that is the MacOS version, but in any case, the desktop ran, but not the plugins. I wiped all that out, and reinstalled with 3.0. Now everything works smoothly. Thanks again! JP -- "It is difficult to get a man to understand something when his salary depends upon his not understanding it." - Upton Sinclair

confusion over updates
by Randy Heiland 25 Jan '05

25 Jan '05

This may have some relevance to Bob Irving's earlier thread on 'recovering', not sure. Here's my situation. For grins, I decided to uninstall my Squeak plugin (actually, this had to do with my earlier post of having installed it twice, under 2 different users on my machine). After uninstalling, I installed it anew from squeakland.org -> Download Squeak now! -> get installer (I'm on WinXP), execute it. Then I run Squeak and check the version - it's 3.8.5976, update #347. I then do an update (Esc->help->update code from server) and, sure enough, it grabs several updates. I then draw a little ditty, attempt to save the project, and get a warning-type msg (which I abbreviate): "Some blocks which ref instance vars are included... These may fail... What do you want to do? Keep going | Stop and look". I stop & look, but eventually it seems to freeze with the overlay grid still up as Bob hinted at. Anyway, I quit, run Squeak again, do another update. This time it updates 27 new files and says it could not load 13 updates files (it says "starting with squeakalpha.org/updates/0375ProjectLoad-tk.cs"). I check the version and am at update #374 (347+27=374). I quit. Run Squeak again, version = update #347. Do another update, this time, it seems to finish successfully. I check and I'm at update #387. I quit, run Squeak again, check version and I'm back to #347. Q: is it true that doing an update is only valid for a current Squeak session and that they don't become part of the executable? Thanks, and sorry to be long-winded, --Randy
