Question about mouse buttons and modifier keys
by Phil (list) 28 May '09

28 May '09

I've run across a few things related to mouse buttons and modifier keys that are giving me some grief: 1) How do I tell Squeak not to emulate a 3-button mouse via modifier keys? (i.e. so red+command doesn't become yellow+command etc.) 2) How can I get blue button presses passed to mouseDown:? 3) Is there a 'standard' way to check the state of option key modifier? (I understand that using the option modifier makes my code Mac-specific which is fine for my needs, I just want to know the best way to do it that is least likely to break in the future.) I am trying to create a morph that uses various button/modifier combinations and several of them seem to be getting swallowed somewhere upstream which is severely limiting the available button/ modifier combos available. Thanks, Phil

I have a doubt. When the bugs fixes on mantis, are integrated on the "main" image? Cheers.

How to read PDF files?
by Daniel Ingalls 27 May '09

27 May '09

Is there code available in the Squeak universe for reading .PDF files? In particular I wish to read a multi-page file produced by a text scanner -- ie probably compressed black-and-white images. Thanks in advance - Dan

Projects using Squeak on Wiki and squeak.org
by Giuseppe Luigi Punzi 27 May '09

27 May '09

Hi, I don't know if exists, I searched but not founded. I'm thinking, like others projects do, if could'nt be interesting, to have a page, where we can add projects developed with Squeak? A page with the names of the projects (dabbledb, Croquet, etc..) url, a little description, and a screenshots of applications, webs, and so on developed with Squeak. I readed thath Juan Vuletich, is asking permission to publish a screenshot of a commercial app he is developing, Germán Arduino has commercial apps too, SmallWorks, etc.. Only a little idea to promote Squeak and his projects. Cheers.

Cuis - Some trouble on the display
by Germán Arduino 27 May '09

27 May '09

Hi Juan, List: I'm having some trouble with the display of Cuis on Xubuntu 9.04, as is showed in the attached pic. I've the display depth on 32, but the transparency effect is present, and noted if I drag a window over other window. Any suggestion will be appreciated. Cheers. -- Germán S.

Dictionary use in SmartRefStream
by Stephan Eggermont 27 May '09

27 May '09

(also on the Pharo list) While taking a look at Seaside issue 262, I noticed that SmartRefStream>>catalogValues: instVarList size: varsOnDisk creates a Dictionary with the default size, while having a pretty good idea of how large it should at least be. Is this called so little that that it doesn't matter? (it is only called in SmartRefStream>>readInsanceSize:clsname:refPosn:) Stephan Eggermont

Re: [squeak-dev] website down?
by Janko Mivšek 26 May '09

26 May '09

Hi Jason, Jason Rogers pravi: > squeak.org is down, It is up again. We will restart the image later because there are some strange Socket behavour on that image which cause socket to stop receiving new web requests. Just restarting the http part of Swazoo solves that problem. For a while... This image is running now for months, that's why its restart could help here. But finding the real cause of this trouble, well, this would be just perfect! Anyone has an idea what can be a problem? > and my message to the webteam was returned as well > with the following error: > > This is an automatically generated Delivery Status Notification > > Delivery to the following recipient failed permanently: > > website(a)discuss.squeakfoundation.org The right address is webteam(a)lists.squeakfoundation.org ! Best regards Janko

Processing a file at image startup (scripting)
by Cédrick Béler 26 May '09

26 May '09

Hi, While delivering a small app (a project scheduler), people asked me if it's possible to execute it by a command line without opening an image. I have a pseudo-dsl to define a project (collection of tasks) that the app is scheduling and so, what I'd like is launching the app by passing a file as parameter. Then squeak "open headless", process the entry file, write an outputfile with results and eventually errors, and exit. I did something but this is a terrible hack :) I'd like to have other idea on that. If we consider: squeak -headless test.image file.in According to the vm man, file.in must be a script (st file with bang notation). I'm not aware of a way to pass a plain text file. So I just hacked ProjectLauncher>>startUpAfterLogin (this is where I get a dnu if passing a file as parameter) so that my file can be processed and the image closed afterwhile. Can people point me a better way of doing that ? My feeling is I need to create a ScriptClass that has a startUp method where file processing can be implemented. Thanks -- Cédrick ps: a related question would be which startUp classes are not necessary if we only need to process a File (do we need InputSensor, etc...)

WikiServer - very nice!
by David T. Lewis 26 May '09

26 May '09

I finally tried downloading some applications to an iPod Touch that I received as a birthday present last year (OK, I'm a slow learner). I tried Google Earth and John's WikiServer. Both very cool. So now I have a complete wiki and web server running on that little gadget. Fits in my pocket, no disk drives, no wires. Nicely done John. Dave

Cuis updated to #0204
by Juan Vuletich 26 May '09

26 May '09

Hi Folks, I've just updated Cuis to #0201. As usual, the files are at www.jvuletich.org/Cuis . In addition to the recent enhancements on black text over colored backgrounds, I also enhanced greatly colored text over any backgrounds. Both do proper subpixel alpha blending now. I had to come up with a few tricks for this to happen using just the old BitBlt rules :-) There are also preferences to disable subpixel AA for colored and black text. And they work reasonable well on all bit depths. Looks surprisingly nice on 8 and 4bpp, and is usable even in 2 and 1 bpp. Hope you like it. Cheers, Juan Vuletich
