Re: OPML parser in Squeak

Hi, Hmm, you're right. Netscape doesn't display it, but MSIE and iCab, both on my iBook do. Sigh. Probably some silly config issue somewhere. I made the jpeg from QuickTime's PictureView from a mac screen shot so it should display on the mac :-) cheers bruce Karl Ramberg <karl.ramberg(a)chello.se> wrote: > > > Bruce ONeel wrote: > > > > Hi, > > There is a screenshot of a simple OPML parser in Squeak at > > > > http://homepage.iprolink.ch/~bioneel/beo/Squeak/OPML-Squeak.jpg > > link or picture seems broken somehow... > > karl

The size of Popope is 153x94x35mm(5.3x3.7x1.4in). The weight is 315g(0.72lb). > I've been running Squeak on my NEC MobilePro 770, which is about > 25cm x 13cm x 3cm, and has a 640x240 screen. I and some Japanese Squeakers are using NTT DoCoMo's Sigmarion. It is OEM of MobilePro 780(VR4121 168MHz, 32MB RAM). Moreover, it is very compact. The size of Sigmarion is 189x107x27mm(7.4x4.2x1.1in). The weight is 485g(1.1lb). And average street price is 40,000yen($370). We love it. http://www.sigmarion.com/ (in Japanese) > It looks like the Popope seems to have a 640x240 screen also. Popope has a landscape QVGA(320x240) and 4096 colors screen. Popope is OEM of CASIO. So it looks like Cassiopeia E-105 about the specification. -- Kazuhiro Abe abee.abe(a)nifty.ne.jp

Re: Squeak 2.7 on iPAQ

Hey, I learn a few things, so it's certainly worthwhile for me. I'd like to switch to Linux, too. But I'm still too frightened of messing up my flash rom in the process, turning my IPAQ into the proverbial $500 paperweight (plus, I haven't found out if those emulators are ported yet...). I have the 2.8 sources compile now, basically, by the way. The link fails, however, with 281 unresolved externals (from the plugins...)

[ENH] PrettyDiffs-nk

"Change Set: PrettyDiffs-nk Date: 29 October 2000 Author: Ned Konz I got tired of seeing major diffs just because someone reformatted a method or changed its spacing. This uses the source code formatting to provide pretty-printed diffs. Turn this on or off in Preferences/browser/diffsWithPrettyPrint."!

>http://homepage.iprolink.ch/~bioneel/beo/Squeak/OPML-Squeak.jpg I couldn't get this to appear, either. I'm using Netscape Navigator 4.74 on a Powerbook (Pismo) with OS 9.0.4. the image just does not load. When I go up one level and save the file to my disk, I can open it in GraphicConverter. It appears to be of type JPEG/JFIF. When I drop it on FileBuddy, it has type "JPEG", creator "GKON" Hmm, maybe I need to add that creator type to preferences somewhere. Also, PictureView does open it. 8-) -- ************************************************** Jeff Szuhay A randomly-directed www.szuhay.org chaotical wetware pattern jeff(a)szuhay.org recognizer/generator.

Re: How to implement dialog sequences ("wizards") with Squeak?

Well, in Morphic I'd implement it by pre-loading all the sub-dialogs (the parts that change) onto AlignmentMorphs. Then as the user navigated back and forth through the sequence, I'd install and de-install the AlignmentMorphs on top of my main dialog. Perhaps I'd make an object for each step of the process that knew how to do itself, and also held onto the pre-loaded AlignmentMorph. So the main dialog Morph would look something like: WindowWithButton Alignment Alignment (this gets changed step by step) Text other morphs as needed Alignment Button (prev) Button (cancel) Button (next) -- Ned Konz currently: Stanwood, WA email: ned(a)bike-nomad.com homepage: http://bike-nomad.com
