Is there a tandard way to attach context menus
by Herbert König 04 Nov '11

04 Nov '11

Hello all, is there a standard way to attach a context menu to a morph? It's fairly easy to do by checking for yellowButtonPressed and manually firing up a MenuMorph. But it is sufficient to implement #addCustomMenuItems:hand: to get an enhanced Halo menu while #addYellowButtonMenuItemsTo:event: and #hasYellowButtonMenu don't help. So is there a predefined way without everybody doing his own? Thanks, Herbert mailto:herbertkoenig@gmx.net

One click setup for 3.9 [win]
by Xinyu Liu 25 Jan '08

25 Jan '08

Hi people, I create a one click setup for newbies. It will do the following things after run: 1. download SqueakVM from ftp.squeak.org 2. download 3.9 images, soruces ftp.squeak.org 3. extract all things 4. create shortcut in desktop and program menu. I found the download process may cost some time, because there is only one download session. The installer can work only in Windows. It can be get from: http://liuxinyu95.googlepages.com/squeak3.9_win_installer.exe I created it with NullSoft installation system scripts. I shared the script code here: http://liuxinyu95.googlepages.com/squeak3.9_win_install.nsi You can change it when 3.9 package updates. Have fun with 3.9! Best regards. Yours, Liu

Added Instance Variables and Methods are not shown in System Browser
by Warakorn Paphrawat 18 Nov '07

18 Nov '07

I developed a little Meta-Programming application, which adds methods to the MethodDictionary of a class and adds instance variables + getters/setters. However, after running this application the changes are not reflected in the System Browser. All new instance variables and new methods are not shown there. On the other side I can run a little test application, which creates a new instance of class (to which I added some methods and variables), which in turn uses some of the added methods and instance variables through getters/setters without any errors. Is there any trick to make these added methods and instance variables visible ? Again, the new methods are correctly integrated into the MethodDictionary with selectors and CompiledMethods according to "aClass inspect". Is there another way to check whether the new methods and new instance are really integrated into a new class? __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

saving image automatically
by Norbert Hartl 01 May '07

01 May '07

Hi, I'm trying to save an image under a different name. I have a image I'm working with (e.g. VNC enabled) and I like to create a derived image under a different name. I use MySetup>>deploy RFBServer doStopServer. SmalltalkImage current closeSourceFiles. SmalltalkImage current saveChangesInFileNamed: 'base-deploy.changes'. SmalltalkImage current saveImageInFileNamed: 'base-deploy.image'. SmalltalkImage current snapshot: false andQuit: true I can still use my working image but if I try to start the base-deploy.image it quits immediately. I tried different settings but the result is similar. Every time I save and quit the image from a method or a doit I get this result. But if I just use SmalltalkImage current snapshot: true andQuit: true in the workspace everything is fine. Norbert

¿Which tool use to code collaboratively?
by Offray Vladimir Luna Cárdenas 01 May '07

01 May '07

Hi all, Me and my students are working on a collective project using Bots Inc and is the time to integrate the parts. I would like to know which is the better tool for that. I have been searching and there are different options: changesets and Monticello (may be more). Monticello seems more graphical and may be more easy. I have installed it opening a Bot workspace (its similar to a classical workspace) and typing: SMSqueakMap bootStrap. after that I get the SquekMap and on it I search and install Monticello but after that I don't know how open it (Bots Inc graphical environment is different from the standard one, so World->open->Monticello Browser is not available. * ¿There is a way to open Monticello browser with a command from a workspace? *¿There are various Monticello packages listed in Squeak map (Monticello 2, MonticelloCVS, MonticelloMultiRep, etc). Which one should we use? Thanks a lot, Offray

Display artifacts in comments/desc.
by subbukk 30 Apr '07

Hi, I see some artifacts (like []) displayed in comments and descriptions in Squeak (3.7-7 vm on Linux, 3.8 image and SqueakV39.sources). I suspect the '\r' line terminator in the *.sources file could be causing it. Is this a bug? TIA .. Subbu

I know that Squeak can play midi files using its built in synthesizer, but is it possible to control external midi devices?

flood erase in Paint tool
by subbukk 25 Apr '07

25 Apr '07

Hi, I wonder if there is an easier way to paint shapes with holes in them by methods other than by erasing pixels at a time? For instance, a nut can be drawn by putting a small circle in a larger hexagon and flooding it (the circle) with "transparent" paint. Is it possible to "unfill flood" (i.e. flood an area with 100% transparency) with the Paint tool in Squeak? Thanks in advance. I really like the way you folks respond quickly and precisely to newbie queries. Subbu

Efficiently writing to a file
by Ian Oversby 25 Apr '07

25 Apr '07

Is this a reasonable way of writing to a file? It seems to run a little slower than I would expect. Thanks, Ian | myFile | myFile := StandardFileStream fileNamed: 'c:/test.txt' Transcript show: (Time millisecondsToRun: [ 1 to: 10000 do: [ :x | myFile nextPutAll: ((x asString) , String crlf) ]]) asString , ' millseconds' ; cr. myFile close.
