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

Omnibrowser help
by Rob Rothwell 14 Aug '11

14 Aug '11

Are there some tips/documentation somewhere on getting the most out of the OmniBrowser? The MulitpleSelection browser looks interesting (sort of like the tabbed browser in VisualWorks), but I don't quite understand its behaviour and what method it decides to show in which pane when you move around or save changes. On the same topic, can anyone point me toward how I could add a new item to the class context menu in the OmniBrowser? I want to add a new template selection menu item (like "new class template" and "new trait template") because I have created a method that creates TWO classes at the same time for an Aida application (A domain model class AND its associated WebApp class). Thanks, Rob Rothwell

Resources with Monticello
by Matthias Korn 15 Apr '10

15 Apr '10

Hi all, how does one work with resources (e.g. image files (GIFs, ...)) used in the application when working with Monticello and in general? Right now I have them on my hard drive and they are read live into Squeak when they are needed. Of course, others don't have the files at hand when working in a distributed fashion. What are the best practices in regard of distribution/packaging as well as performance?

Animating Windows XP, workflow and Croquet
by Douglas Krueger 28 Feb '10

28 Feb '10

Hi, I'd very much like to automate things on our corporate Windows XP desktops, our Unix servers and to experiment with Croquet for multi-user applications. I'm specifically thinking about inter-departmental work flows, integrating local and cloud applications. Any experience or help with this would be most appreciated. Thanks! _______________________________ Doug

Guidance on squeak (trunk) plugins on Ubuntu. Or: how do you get beeper to beep?
by Jerome Peace 21 Feb '10

21 Feb '10

I am using squeak on Ubuntu. Actually I find my self hearding mice. Pharo, Cuis, Etoys, squeak itself (several variants) and now Edgar's Funsqueak are running around here. Well, mostly they are sleeping. They are certainly not making much noise. I am currently trying to sort out the plugins needed for certain of the variants. What I know how do to do: I have downloaded squeak etoys from squeakland (a while back) and installed it into the shareable area. I can launch etoys with the a copy of the launcher provided. It runs and it can make noise. I have also downloaded via Add/Remove applications squeak 3.10.2 pretrunk. The plugings that come with this don't include the correct sound plugin. So out of the box it runs silently. The launcher for 3.10.2 cab be jury rigged to use the squeakdev vm but to include the etoys plugins. Sound worked but there were other problems. Back to the drawing board. I ended up copying the 3.10.2 plugins into a folder in my home directory and adding a copy of the sound plugin from etoys. That got sound working in 3.10.2 (pre-trunk) and avoided the other problems. Of course, trunk now has closures and needs a closure vm. Having learned the launcher trick. I can load squeak images into my home directory (I don't need to install them in usr space) and run them from vm's which may also be in my home space. Pharo comes with a closure vm for linux pre-assembled. I have that in my home space. I run the closure squeaks (both Pharo and trunk) by creating launchers to open clousure images with the Pharo vm. The vm directory has various subdirectories with what look like plugin sourse and binaries in them. If I launch with the command '.../pharovm' '.../mysqueak.image' the squeak image will run. Silently. Sigh. If I modify the command by adding '-plugins '.../myPluginDir' Then the image will load, flicker and just quit. *Sigh*. So at this stage of my knowledge I am forced to run *silently*. That's not really acceptable. What do I need to know about plugins to get sound working on my Ubuntu system? Details: Ubuntu 8.04 Pharo vm (and plugins) from pharo-vm-0.15.2d-linux.zip Current images Squeak trunk #9371 and Fun Squeak #9400 So I am asking for help in the form of a backgrounding in plugins. How to install them. Where to install them. How to know if they are in their right places with all the right extentions mime types etc. How can I command current squeaks to speak? Yours in curiosity and service, --Jerome Peace
