Hi Folks. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Jesse Welton [jwelton(a)pacific.mps.ohio-state.edu] wrote: Is there any way to make Squeak recognize a change in the window size, without restarting?

The issue is: if you are running Squeak in an un-maximized window and you use the window handles to make the window bigger, Squeak does not recognize this fact until you manually choose to "restore display". The problem happens within MVC and morphic. Jessie: After you resize your window, right mouse click to bring up a menu. The "restore display" command should be right on top (I think it's the 3rd menu item -- I'm working from memory here :-) ). I have hopes that when we get native event support implemented, we can make the re-paint after resize an automatic feature. Cheers! ---==> Chris

Problems with Colors in 2.5. Windows Port
by Torsten.Bergmann＠phaidros.com 27 Aug '99

27 Aug '99

Hi, I use Win NT4.0 SP5 with the Squeak 2.5. release and have problems with changing morph colors in 32bit color mode. I've done the following: - opened a virgin 2.5. image - set color depth to 32bit ("appearance" menu) - open a new morphic project - create a morph (for instance an ellipse morph) - select "fill style"-"change color" in the morph menu - after selecting a color, it gets always translucent !!! Another thing: - if I switch back to another mode with less colors (for instance 16bit) I can change the color - looks nice. Then, back in 32bit mode the color will stay - also nice. But the first time I try to change the color it gets translucent again. The same thing happend if I used other morphs. Maybe it has something to do with the change in the morph coloring (in 2.5 you can switch between gradient fill, solid fill color, ...) In Squeak 2.4. it works. Also the 32bit mode look more ugly comparing to 2.4 if I use a desk background picture. Is this special to Windows or do we have this problem on other plattforms too ? Any ideas ? -Torsten

If you running in Squeak in a window as opposed to full screen, you can resize the window by dragging the lower right corner. 2. In the World menu/appearance... menu, toggle back and forth between full screen on and full screen off. Some combination of the above will get you where you want to be after changing the resolution.

RE: Problem with PWS and Squeak2.5
by Jarvis, Robert P. 27 Aug '99

Come to think of it, I think there's a command line option on the Windows VM to fire up Squeak automagically as a service. I've cross-posted this to the squeak mailing list, so perhaps someone more knowledgeable will answer.

Text Wrapping Demo (was RE: Car and Steering wheel demo and Squeak-DEMOS)
by Steve Wart 26 Aug '99

26 Aug '99

I was able to play "car.tape" and it was definitely cool. Thank you for this. I tried "textwrap.tape", however, and the effect was a little disappointing. Did you upload the correct file? The cursor wandered around the screen a bit, saved my image, played around with the menus some more, and that's about it. I was actually hoping it would show how bookmorphs work. I need to get some ideas down and I was debating: MS Word or HTML. Bleah. I downloaded Xanadu, but the green release is all in C, so I won't be trying to get that up too quickly. But I also read some of their web docs, which got me looking at some web sites describing collaborative work environments (e.g. http://eies.njit.edu/~turoff/Papers/delphi3.html) and I thought it might be worthwhile to try and create something around this using PWS. Swikis are great, but the web-based editor is quite poor. It should be fairly easy to set up something using bookmorphs, however, if I can figure out how to make them work properly. EventRecorderMorph should provide an error message when it is unable to open a file (or "read a tape"), this makes things quite confusing because it does not seem to work unless you enter the full path name. It also has a hard-coded assumption that lines end with Character cr. Aren't there higher-level constructs for reading a file a line at a time than the following pattern? [aStream atEnd] whileFalse: [ line := aStream upTo: Character cr. lineStream := ReadStream on: lineStream. etc... ] Cheers, Steve > -----Original Message----- > From: Stephen Pair [mailto:spair@advantive.com] > Sent: August 26, 1999 9:40 AM > To: squeak(a)cs.uiuc.edu > Subject: RE: Car and Steering wheel demo and Squeak-DEMOS > > > > I think morpic tapes are a good way to explain morphic stuff.

Car and Steering wheel demo
by Stephen Pair 26 Aug '99

26 Aug '99

I've placed a recorded demo of creating a car and string wheel and then hooking them up at: http://www.advantive.com/squeak/car.tape Instructions: 1. Get a fully updated standard Squeak 2.5 image 2. Start it (don't resize anything). 3. Create and Enter a Morphic project 4. Open an EventRecorderMorph and position it precisely in the top left corner of the screen (aligning the pixels with the top left) 5. Select "readTape" and enter your downloaded copy of the above file 6. Select "play" and watch Note, the EventRecorder is very sensitive to the positions of things. Also, if you system runs more slowly than mine, it might not work properly. - Stephen
