Ah, OK. I didn't know about the window colour dialog. Interestingly enough, it showed my ImageMapEditor's colour as white (which is why SystemWindow "ignored" my #windowColorSpecification - here I thought I'd set a colour of a sort've minty green, when it was actually white!). While I was fiddling with the dialog, I tried out the Pastel and White sections. When I changed back to the Bright settings, my ImageMapEditor suddenly showed the correct colour! Et voila, it all Just Worked.

Two new Team leaders decided!
by goran.krampe＠bluefish.se 03 Mar '05

03 Mar '05

Hi all! Ok, now it seems we have finally wrapped up who is taking the lead of the ToolBuilder Team and the Packages Team. Brian Brown is from now on the leader of the ToolBuilder Team (not leading the actual ToolBuilder project, but making sure it gets into 3.9). Brian has been active from the start in that project and he seems like the perfect fit. Avi Bryant is from now on the Team leader of Packages which of course also is a perfect fit given Avi's stuff in this area - PackageInfo, Monticello etc. So with this posting the ball is in your hands guys. :) regards, Göran

problems running Swiki 1.4 as WinNT service
by SPINIELLI Enrico 03 Mar '05

03 Mar '05

Hi, I successfully installed and run Squeak 3.6 :: Comanche 6.2 :: Swiki 1.4 but when I try to run swiki as a windows NT service it does not work. The log file says: Thu Mar 03 10:56:44 2005 ComSwiki started with the following command line and no command line is provided. The command line I used is the following: C:\ComSwiki\Squeak.exe -memory: 5 -log: "C:\ComSwiki\swiki.log" -service: "ComSwiki" C:\ComSwiki\squeak.image When I checked the "Allow Service to Interact with Desktop" checkbox in the Service Startup configuration I got: Could not open the Squeak image file " There are several ways to open a Squeak image file. You can: 1. Double-click on the desired image file. 2. Drop the image file onto the Squeak application. Aborting... Any suggestions?

Qtopia Squeak is in the bitbake (OpenEmbedded) build environment
by Torsten Sadowski 03 Mar '05

03 Mar '05

Hi, my patched version of Yoshiki's Qtopia Squeak VM (3.4) has been put into the bitbake build environment. This means you should be able a Linux VM for QtEmbedded for an Ipaq or Simpad if (big IF) the bitbake tree is in a good mood. For instructions how to get started see http://openembedded.org/ The Simpad version is tested, the Ipaq version should work and the Zaurus (Sharp ROM) version is most probably broken. Bitbake is temperamental at best. There is only one tree which gets broken at a regurlar basis. If it doesn't work one day try again next day or the day after. If you ever thought Squeak was difficult because it is a moving target you will appreciate its rock solid stability :-) Torsten

Problem with running Squeak 3.7 as service on Win XP
by Frank 03 Mar '05

03 Mar '05

Hi, I used the method described in http://minnow.cc.gatech.edu/squeak/105 to install squeak as a service under windows XP. During the installation I get a message that the service was installed successfully. However when the service is started I notice: 1. no icon in the tray 2. no response from the webserver (seaside application), which does work when loading the image manually. 3. the log shows that the service was started with an empty command line. I enabled desktop interaction in the service control panel. After doing this I get an error during service startup. The vm complains that the image named "¡¡€¡£" (garbled string) cannot be started. Seems to me that the image file name is not put on the command line during service startup. However a check on the services section in the registry shows that the image is properly entered. Any ideas to resolve this are very welcome as I am no windows expert. Best Regards, Frank

ImageSegments
by Bruce O'Neel 03 Mar '05

03 Mar '05

Hi, I have a silly question about ImageSegments. I seem to be able to write one with: (ImageSegment new copyFromRootsForExport: (Array with: fsw with: fsw class)) writeForExport: 'myFile.extSeg'. the above took no thought on my part, it was just from the documentation of ImageSegment. In my above list fsw the instance variable I want written out. Now, how do I read it back in without using FileList? My file list (MVC only image) doesn't seem to have the load as project option:-) Thanks! cheers bruce -- edoneel(a)sdf.lonestar.org SDF Public Access UNIX System - http://sdf.lonestar.org

IRCe - new features
by Frank Caggiano 03 Mar '05

03 Mar '05

If you are using IRCe (and if you're not why not?) I just put a new version on SqueakSource, 10.5.3. http links are clickable. Tabbed completion of nicks was already in the code but now if the nick starts the line a ';' is appended. If the nick is inline no : is appended. (Thanks to Ken for suggesting this). Know problems: Right now the code assumes the link ends with a space or ends the text line. If the link ends with another char (such as . or ) ) that char gets included in the link. If mIrc colors is selected in the setup>current options window the link color will not change. The link is still clickable however. The browser opened will be whatever the default browser is in your image. As scamper isn't really of much use right now you may want to load 'ExternalWebBrowser' from SqueakMap. I've been using i for some time now and It works great for all URL's not just IRCe. If your on a Mac you may want to also load 'Applescript' from SqueakMap. I'm not much of an IRC user. My exposure to other clients is limited so I'm not sure what features others may find useful in a client. So if you have any suggestions, comments or criticisms let me know. regards ------------------------ Frank Caggiano frankcag at crystal-objects dot com http://www.crystal-objects.com The best education for the best is the best education for all.

[BUG] Morphs and lefthand-side vertical scrollbars
by Markus Fritsche 03 Mar '05

03 Mar '05

Hi! I have the preference "inboardScrollbars" on, "scrollBarsOnRight" off and "alwaysShowVScrollbar" off (Scrollbar? ScrollBar? scrollBar? Just kidding), and newly opened Workspaces do display the contained text a bit to the right (the size of the scrollbar), when I resize the window, the text is alligned properly. Regards, Markus -- http://reauktion.de/archer/

[Q] how to cache a drawn morph
by Baveco, Hans 02 Mar '05

02 Mar '05

I have a morph that takes long to draw, with several submorph with extensive #drawOn: aCanvas methods. I would like to cache the result of all this drawing of submorphs but can't figure out how to do this correctly, especially my problem is when & where to create this cache (a Form, I suppose). Adding the following naive method to my morph almost does it right, except that the created Form (the inst.var. image in the code below) will also have other morphs' content on it, when my morph is partly hidden by other morphs. The #forceToScreen: does not have any noticeable impact on the outcome, I think. drawSubmorphsOn: aCanvas "Display submorphs back to front. First attempt at caching a Form (otherwise this method should be deleted)" submorphs isEmpty ifTrue: [^self]. (image isNil or: [image extent ~= self innerBounds extent]) ifTrue: [super drawSubmorphsOn: aCanvas. aCanvas forceToScreen: self innerBounds. image := aCanvas contentsOfArea: self innerBounds] ifFalse: [aCanvas paintImage: image at: self innerBounds origin] In the hierarchy of drawing morphs, this is probably not the right place to create/update the cache? How do I obtain a Form with only the drawings of my morph's submorphs on it? Is there a standard way to achieve this caching (there is a CachingMorph somewhere, but I don't understand how it is supposed to work).. Any help much appreciated! Hans

I'll make sure my Models behave themselves. <snip> > The window opening (assuming you're opening a SystemWindow) > will look up the > window color itself. If you're getting a color for a > non-SystemWindow, you > would do it as you describe. I see that sending one of the #open* messages calls #paneColor which, under some conditions (model notNil being the most important), will ask the model for its #defaultBackgroundColor. I can't see how it gets the window colour from the #windowColourSpecification though. MethodFinder gives me three senders: Finder class>>windowColourSpecification just delegates to RefactoringBrowser class>>windowColourSpecification, TestRunner class>>initialize does The Rude Thing and calls Preferences class>>setWindowColorFor:to: and Preferences class>>windowColorTable just returns an Array containing implementors of #windowColorSpecification...
