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!

MIDI support
by stan414 31 Oct '07

31 Oct '07

(cross posted to beginners and audio) Hello everybody. I'm developing a project for which I need a MIDI music keyboard as input. I started out on a Windows box, and all the components seemed to be there. I've since swapped to Ubuntu, and it seems that the MIDI support is a problem. >From here: http://www.nabble.com/Midi-Input-with-Squeak-tf3749891.html#a10596965 I see that Eric asked the same question in May, without resolution. It appears that what I need to do is to build a vm with the MIDI plug-in - http://www.nabble.com/modules,-plugins,-primitives,-and-MIDIPlugin-t3728328… However, from here: http://www.nabble.com/modules%2C-plugins%2C-primitives%2C-and-MIDIPlugin-tf… it looks like even with a vm build I may not get MIDI in. As a newbie, I'm not too keen to get into vm building just yet. So my question is/are, is there any image available with MIDI support? If not, is the build thing a big undertaking? Are there any other creative approaches (e.g. use an old version of Siren, wait for Siren port proposed at http://www.nabble.com/Siren-on-Squeak-tf3802040.html)? Is my analysis of the state of play correct? Thanks for any help- I really don't want to have to go back to Windows, or worse to Java. Stan PS I tried the Etoys/OLPC image, SimpleMIDIPort midiIsSupported returns false there too. On Windows image it returns true. -- View this message in context: http://www.nabble.com/MIDI-support-tf4714472.html#a13476201 Sent from the Squeak - Beginners mailing list archive at Nabble.com.

using collect on a ReadStream
by Norbert Hartl 30 Oct '07

30 Oct '07

Hi, I get a ReadStream from some part of a program which is created this way stream := (ReadStream on: #( #(#a #b) #(#b #c))) I like to use collect: on that stream: stream collect: [:each| 'k',each first] Is there a possibility to specify the resulting collection produced by collect. The problem here is the species call with an add: call afterwards which is not appropriate (the debugger said :) ) thanks, Norbert

Concrete classes... multiple users
by John Almberg 29 Oct '07

29 Oct '07

One of the cool things, I think, about Smalltalk is that Classes are objects... i.e. concrete factories that can be modified at runtime to produce objects in different ways, depending on the runtime situation. I just find this so much more intuitive, compared to how classes are done in other languages... But I think I may have used it in a naive way... For example, I needed an Adapter class that could produce standard Item objects by connecting to a variety of legacy database tables, converting the non-standard item records into standard Item objects. This way, the consumer of those Item objects doesn't care where the items come from. Originally, I thought I would only have to make these connections, one at a time. I.e., I'd program the Item class 'factory' with the legacy database hostname, username, password, and then just start asking for Items. The Item class would then go out to the database, fetch the proper row, create an Item object, initialize the instance variables, and return it to the Item object consumer. This is intuitive, cool, and it works. Then the requirements changed and I needed to connect to multiple database *at the same time*. But there is only one Item class object! This really muddles things up, because I basically have to update the Item class variables every time I need an Item object. No longer cool! Did I just misuse this feature? Should I have built two Adapter Objects, instead? Am I missing something obvious? Is a little knowledge a dangerous thing? :-) TIA... John

where's the halo?

Objects, sliders etc, taken from the parts flap, don't have halos. How do I get the halo on a slider to appear? -- View this message in context: http://www.nabble.com/where%27s-the-halo--tf4697230.html#a13426907 Sent from the Squeak - Beginners mailing list archive at Nabble.com.
