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!

Dead keys on Ubuntu
by Fahr Jahrel 09 Aug '07

09 Aug '07

Hello, all-- I've been trying unsuccessfully for some hours to make my Squeak image accept diacritical characters under Ubuntu 7.04. I've tried all possible combinations of the -textenc, -encoding, and LC_CTYPE options I could but none worked. The diacritical characters either don't display or display incorrectly. Ironically, if I run Squeak via Wine, the diacritical characters display correctly. Any help pointing me to the right direction would be appreciated. My system configuration today is: Distro: Ubuntu 7.04 Squeak: 3.9-8 #5 Tue Oct 10 11:56:09 PDT 2006 gcc 4.0.3 Squeak3.9alpha of 4 July 2005 [latest update: #7021] Linux ubuntu 2.6.15-27-386 #1 PREEMPT Sat Sep 16 01:51:59 UTC 2006 i686 GNU/Linux default plugin location: /usr/local/lib/squeak/3.9-8/*.so Image: Tried with the vanilla 7067 image, the lasted squeak-dev image, and even Ramon Leon's image. :-) Any help is appreaciated. Thanks, Fahr

Hi, could someone recommend a PostgreSQL client for Squeak? At this time, the current version in SqueakMap Package Loader hasn't been blessed to work with Squeak 3.9 (7076). Thanks in advance, -Conrad

Its returning the actual matched class object.

Proper fractions?
by Blake 28 Jul '07

28 Jul '07

Hey, guys: Any way to make the fraction class print itself out with its integer part separate from its fractional part. In other words, if I have 4/3 (an "improper" fraction) can I make it print out as: 1 1/3 ? I mean, I know I can write a routine that does this but it seemed odd to me that one doesn't exist. (And who came up with that whole "improper" terminology? Some guys with small numerators, I'd bet....) ===Blake===
