I have attached a screen capture of the debug screen after losing what I was working on. My student single-clicked on Publish It, the screen "gridded", and we lost control. As far as I can tell, the program defaults to publishing somewhere else besides the local drive and hangs while trying to find that other place. My question is this -- is there any way to get the work back?

wsyiwyg printing; replicate obj
by Randy Heiland 08 Feb '05

08 Feb '05

First, thanks to everyone who's replied to my recent numerous questions - Alan, Ned, etc. I feel like I'm putting myself through a crash course in Squeak - and loving it. In reference to one of Alan's replies, I was aware of Squeak's wonderful object oriented design, but just didn't appreciate it in practice. I'm starting to... Q1: I've created a Book and would like to print it out (this is for a poster). I've tried the Book Menu -> copy & print -> postscript, but the end result is, well, weird. Text has extra spacing, graphics from one Page appear on another, arrows have their borders drawn, etc. Not surprising really, given my past experience with postscript generation. So, my question is - how do people print projects? I'll probably just use the Menu -> export -> PNG for each page and print that way. More laborious, but the result is nice. Q2: replicating an object in a script. I've learned (from my student) of the 'sketch stamp' which does this - and I found it when doing a 'Search' on 'stamp' in the Viewer. Is the 'stamp' also in one of the viewer's categories (basic|scripts|etc.)? If so, I couldn't find it. Thanks again, Randy p.s. I'm getting close to putting my project on a web page and will notify the list when I do. There's always "just one more thing I'd like to try..." :)

Is it possible to join, or group together, 2 or more objects into a single object? Thanks, Randy

RE: [Squeakland] joining objects

I've been trying to figure this out as well. I know I can use the lasso to take a picture, but I would really like a CompositeMorph kind of thing (so that I can take it back apart again). -----Original Message----- From: squeakland-bounces(a)squeakland.org [mailto:squeakland-bounces@squeakland.org] On Behalf Of Randy Heiland Sent: Sunday, February 06, 2005 6:29 PM To: squeakland(a)squeakland.org Subject: [Squeakland] joining objects Is it possible to join, or group together, 2 or more objects into a single object?

selecting colors
by Randy Heiland 07 Feb '05

07 Feb '05

I've created object A then I start creating object B and decide I want to use an exact color that I used in A - how do I select that color? More generally, when I choose a color from the palette, is there a way to get its actual RGB values and enter those when selecting a color later? Thanks, Randy

report bugs
by Christian Grune 03 Feb '05

03 Feb '05

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

(a 'no' answer to this will cause me to reconsider this >approach) 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. >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. 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
by Randy Heiland 02 Feb '05

02 Feb '05

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? --Randy

Viewer in a Book's Page [was PPT presentation]
by Randy Heiland 01 Feb '05

01 Feb '05

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? --Randy
