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!

invoking a *class* method from a workspace
by mstram 05 Jun '07

05 Jun '07

What's the trick / catch ... if there is one for invoking a class method from a workspace? I created a Class "MikeTest". - Added an instance method : "imethod" MikeTest >> imethod ^ 'I am an instance method' - Added a Class method MikeTest class>>cmethod ^ 'I am a class method' ---- Then in a workspace : t := MikeTest new. t imethod (alt-p) -->> 'I am an instance method' (As expected) t cmethod (alt-p) gives 'MessageNotUnderstood' http://mstram.freepgs.com/img/message_not_understood_when_evaluating_class_… The debug trace has 'UndefinedObject>>Doit' ... which seems strange to me ... does that mean the workspace doesn't understand how to send a class method ??? Puzzled (again).

usage PolygonMorph
by Jerome Peace 31 May '07

31 May '07

usage PolygonMorph Hi Konrad, Part of the answer depends on what you want to do with them next. If you just want hexagons one easy way is to start with a StarMorph (using a 3.9 or later squeak). Add handles. Increase the number of points by one by clicking the up arrow in the center. Then use the left arrow to increase cycle thru the skip stars until you get to the one that looks like a hexagon. The outer handle allows you to turn and scale the star. If you are not using 3.9 the changesets and demo are here: http://209.143.91.36/super/647 StarMorph-wiz With these repairs stars are freed to have any number of points and any amount of pointedness. Of course it might be fun to use Karl's method a few times too. What works best depends on what you want to use if for. Hth, Yours in curiosity and service, --Jerome Peace *** > >[Newbies] usage PolygonMorph > >Konrad.Krentz Konrad.Krentz at web.de >Wed May 30 19:44:02 UTC 2007 > >Hi @ all, > > > >I'd like to know how to create a hexagon using PolygonMorph class. > > > >Thanks! > > > >Konrad *** ____________________________________________________________________________________ It's here!

classes and subclasses and inheritance
by David H. Shanabrook 31 May '07

31 May '07

I am slowly figuring things out, but have gotten stuck. Maybe this is something basic? I am using DrGeoII. I have defined a DrGPolygoneMorph which is a subclass of DrGPolylineMorph then a subclass of PolygonMorph. I am trying to flip this object and using the method flipHAroundX:nil This works when I create a PolygonMorph, but doesn't seem to do anything to my DrGPolygoneMorph. Doesn't inheritance mean is should work identically? david

package browsers
by Nick Ager 26 May '07

26 May '07

Hi, What is the difference between the "Package Universe Browser" and "SqueakMap Package Loader"? On a related question, I'm trying to understand the difference between packages listed in SqueakMap/Universe Browser and those listed in the "Monticello Browser". I understand that Monticello is a version control system which contains the latest although not necessarly stable release code whereas the packages listed in SqueakMap/Universe Browser should link to stable releases of the code. Is this understanding correct? Is packaging part of an image release cycle or a separate process? Thanks again Nick

which code browser to use?
by Nick Ager 26 May '07

26 May '07

Hi, What are the pros and cons of the different code browsers I see in my image (it's based on Damien Cassou's squeak-web-95-2.zip). I see: * Browser (appears to be the default) * HierarchyBrowser * OBSystemBrowser * ShoutOmniBrowser * eComspletionOmniBrowser * Tric-RefactoringBrowser * WhiskerBrowser * OmniBrowser I find myself switching between different browsers and not finding one which provides a superset of browsing functionality.I feel must be missing a trick. Is there a prefered browser amoungst more experienced users? How do I register a prefered browser as the default for alt-b and tools tab->browser? Thanks Nick
