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?

User account for squeak wiki.squeak.org
by Miguel Enrique Cobá Martínez 24 Jul '09

24 Jul '09

I am trying to edit a page but I can't find the place to create a user account. When I click the edit button in some page from the wiki, Iceweasel (Debian's unbranded Firefox) ask for a username and a password. When I click the history button, I get a list of changes and in the user column I see strings like: ACCF7AF4.ipt.aol.com so this makes me think that the edition of pages it is open and your IP address is used as your username. But, the problem is, I can't pass the user/password request. The user/password dialog says: http://wiki.squeak.org solicita un usuario y contraseña. El sitio dice: "/squeak/*" Something like: http://wiki.squeak.org needs a username and password. The site says: "/squeak/*" And if I click the cancel button it responds with: Unauthorized for: /squeak/* Can you please tell me what is the process to edit a page in the wiki.squeak.org? Thanks, Miguel Cobá

MonticelloBrowser question
by Ch Lamprecht 23 May '09

23 May '09

Hello, could anybody help me to understand, how to use MonticelloBrowser? (Working with 3.9 #7067) I read SBE and it says: " The right-hand pane lists all of the source-code repositories that Monticello knows about, usually because it has loaded code from them. If you select a package in the left pane, the right pane is filtered to show only those repositories that contain versions of the selected package." However, I don't see that happen. If I select e.g. OmniBrowser in the left pane, the list in the right pane is reduced to a local path on my filesystem (the package-cache). But if I deselect all in the left pane to see all the repositories in the right pane, then select 'http://source.wiresong.ca/ob' and open the repository I get a browser containing lots of newer version of OmniBrowser (and other packages). Now these repository browsers always take some time to load and I have to check different repositories by hand to find the latest version. What is the right way to search (and update) to the latest release of a package? Thanks for your help, Christoph

Is there a VMware image of Squeak and Apache?
by Andy Burnett 06 May '09

06 May '09

Following on from my question about SSL and Squeak (thanks Lukas and Kyle for your answers - very helpful). I realised that what I really need is a version of Apache which is configured to run with Squeak (or Gemstone), and which already has all the 'bits' set so that I can concentrate on the Smalltalk without having to worry about a totally different system - that I know nothing about. Does such a thing exist? Or, would it actually be a dangerous/unhelpful idea because Apache must always be configured differently for your specific needs yada etc. etc. Ideally, I would like the simplicity of a Squeak image, expanded to include the whole web serving environment. cheers AB

Hello, Could someone point me to an example of the best way to combine 2 images using color masking. I am using an ImageMorph with an image loaded and would like to overlay other images. I am thinking of trying BitBlt, but am wondering if there is an easier way. Thanks.

Is HttpView2 still alive and working?
by Andy Burnett 30 Apr '09

30 Apr '09

Hello I want to build some simple web services for an application I am thinking about. The idea is that the client apps could be coded to run on the iPhone or in Flash, so all I need on the back end is a simple storage and retrieval system. I stumbled across HV2 and it seems to be quite a neat system. However, it hasn't been updated since 2007 (AFAICT) and it seems like things in the Squeak world have a habit of never dieing. So, is it still alive, or have things like Seaside meant that it is now redundant? Thanks Andy

purge of graphics objects
by Torsten Bergmann 28 Apr '09

28 Apr '09

If you delete a graphical morphic object using the halos it may still be references in the trashcan: >From the world menu select "objects" to open the objects browser. In the "Basic" category you will find the trash can. Drag it on your desk. You can also open it via "new morph" -> "from alphabetical list" -> "TrashCanMorph" or by evaluating "TrashCanMorph new openInWorld" By double clicking the trashcan you will see it's contents and when you click on the "E" in the top right corner you will empty its contents. After that run a garbage collection manually. There is also a class "Imports" referencing imported resources. You can inspect it via "Imports default viewImages" The scripting system also blows up the image a little bit, just evaluate "ScriptingSystem inspectFormDictionary" if I remember correctly...
