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

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

authenticating Squeak to a proxy
by wgsilkie＠ihug.co.nz 04 Apr '08

04 Apr '08

Hello, I am new to Squeak (but not OO programming), and reading the "Squeak by Example" book, but I can't figure out how to get Squeak to use a proxy that requires authentication. When at home, this is not a problem, but at my school, I can only access the Internet through an HTTP proxy, and it requires that each student enter his or her username and password. I've found where in Squeak I need to tell it what port to use, and the server name, but there's nothing there for a username or passkey. Is there a way to tell Squeak to authenticate itself as a particular user? Thanks, Aidan

SBE and Squeak versions out-of-sync?
by David Finlayson 01 Apr '08

01 Apr '08

I'm on vacation and learning Smalltalk is how I'm spending my evenings (family is young and goes to bed early). I downloaded a copy of Squeak by Example (Version 2008-3-10) and the latest squeak for OS X: Squeak3.9-7067mac vm 3.8.18beta1U With the recommended dev-image: sq3.9.1-7075dev08.03.1 Considering the date of the most recent update to the book, I was surprised (and very confused by) a number of major differences between the Squeak image described in the book and the one on my computer. I've waisted a lot of my spare time trying to figure out what the heck is going on. The main problems are differences between the World menu (completely reorganized, apparently), expert vs novice mode (no "Do it" in novice mode but this was the default mode) and what looks like some major changes in the System Browser (for example, the need for packages before defining a class, the lack of a second window for editing class comments, etc. Right now, I can't define a new method as described in Section 2.2 the method template doesn't show up when I click on -- all -- in the protocols pane. Doubtless it is user error, but I'd like to get back on track (maybe I downloaded something I shouldn't have?). Any suggestions? I checked the on-line errata for the book and it does not mention any of these interface changes I'm seeing. Thought that I would post here rather than waist more time flailing around. Sorry so long winded. David

report / graph generator
by Danny Chan 31 Mar '08

31 Mar '08

Hi everybody! I am currently looking into using squeak for data analysis at work. At the moment, I mostly need to postprocess data files created by other programs and put graphs and overview tables into some kind of PDF report. Are there any existing solutions for such tasks? Later, I would like to move some of the code for data analysis from older C programs to Smalltalk. Is there a capable matrix/vector library, like numpy/scipy for python? Thanks, Danny --------------------------------- Lesen Sie Ihre E-Mails jetzt einfach von unterwegs mit Yahoo! Go.

Enumerate Package Versions
by Rob Rothwell 29 Mar '08

29 Mar '08

How can I enumerate the Packages I have loaded to increase my bug reporting abilities without having to type all the package versions I have? I tried PackageInfo allPackages do: [:each | Transcript show: each packageName; cr]., but that only gets me the base package name, not the one with versions which shows up in Monticello. An instance of PackageInfo doesn't seem to have a version that I can find. Thanks...I have tried figuring out how Monticello is doing it, but just can't seem to find it... Rob

Hi Nathan, and welcome to this marvelous world. Once you learn Smalltalk, there aren't other language where you will be develop better :D I don't want to speak about all the virtues of Smalltalk, I know you will discover it step by step. Only, give it time. Exists one excelent tutorial from Steve Wesses. This tutorial, aid you to develop a little game using all aspects and features of Squeak. From creating a class, to sharing this code with Monticello and so on. This tutorial is on: http://squeak.preeminent.org/tut2007/html/index.html Good luck, and fun ;) And remember, Squeak community is not so big, but is very active :)
