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

Float comparsion
by Camillo Bruni 27 Feb '09

27 Feb '09

Hy all, I recently tried to compare two Float which apparently should be (nearly) the same. I have to following excerpt: a := (Float halfPi / 2) tan a = 1.0 The comparison evaluates to false, although it should be 1.0. How do I compare Floats so I get useful results? I'm using Squeak 3.8.18beta3U VM and the Squeak3.10.2-7179-basic.image on Mac OS X 10.5 with an Intel Core 2 Duo. Thanks, Camillo

RFB-VNC vs RemoteFrameBuffer
by Miguel Enrique Cobá Martínez 27 Feb '09

27 Feb '09

In squeak universes there are two options for a VNC server: - RemoteFrameBuffer version 34: Category: Network Maintained by: Damien Cassou <damien.cassou(a)gmail.com> Downloads from: http://www.squeaksource.com/RFB/RFB-ikp.3.mcz where RFB-ikp.3.mcz if from Ian Piumarta from 2007-02-20 06:12:40 - RFB-VNC 1.0: Maintained by: ikp Downloads from: http://www.squeaksource.com/RFB/RFB-ikp.3.mcz Homepage: http://www.squeaksource.com/RFB this is the same monticello from RemoteFrameBuffer version 34, so I suppose this is just a repackaging with a more meaningful name. - RFB-VNC 1.2 Maintained by: ikp Downloads from: http://source.lukas-renggli.ch/unsorted/RFB-lr.10.mcz Homepage: http://www.squeaksource.com/RFB Although this version has the same homepage that the version 1.0, it specifies also Lukas' site. From Lukas squeaksource: Filename: RFB-lr.10.mcz Author: Lukas Renggli Timestamp: 21 December 2008 10:23:08 am UUID: 491315b5-d566-4240-8a15-55be3a27619a Ancestors: RFB-lr.9.mcz Message: - made it work in the latest pharo Downloads: Web: 16 Squeak: 2 So, according to this, the RFB-VNC 1.2 is the version that is and will be (at least for pharo will be) maintained. Lukas, is this correct? Should I use RFB-VNC 1.2? Thanks, Miguel Cobá
