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

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

I'm trying to load the Rome package from Squeaksource, and I keep getting error messages about needing certain other classes. Is there an easy way to find out which packages contain those classes?

Debugging Squeak
by K Chang 01 Feb '08

01 Feb '08

Hi, I was trying to make some modifications on Squeak. After some coding work,I found my Squeak now consumes almost 95% CPU time and more than 100M mem, and it seems like it won't slow down unless i close it. I've already saved the image and the CPU consuming problem comes out right after starting Squeak with out running any code I wrote, my question is, is there any debugging tools that i could find out which process or chunk of code is slowing down my squeak ? I've tried MessageTally,didn't work. Thanks~ K.Chang

Where are the dialog boxes for input/output?
by LoneHunter01 31 Jan '08

31 Jan '08

I'm trying to do basic i/o using Squeak and I've looked through my browser, but I can't seem to find anything that allows simple (keyword: simple) dialog. All I want is to ask the user a question (What is your name?) and then respond using the string they provide (Hello, name). But I can't even figure out which morphs open popups. My friend (equal knowledge of SmallTalk) did this in under 2 minutes using Visualworks, so I know it's possible. Any help would be appreciated. -- View this message in context: http://www.nabble.com/Where-are-the-dialog-boxes-for-input-output--tp151226… Sent from the Squeak - Beginners mailing list archive at Nabble.com.

Tracking down an obsolete class from a RefactoringBrowser / ClassOrganizer
by stan414 30 Jan '08

30 Jan '08

I have been experimenting with some metaprogramming, which left a ton of obsolete classes. Have been able to cure most of them, except for this last one. Pointer Finder shows: #EventManager -> EventManager class classPool: Dictionary #ActionMaps -> WeakIdentityKeyDictionary a RefactoringBrowser -> IdentityDictionary #getCompletionController -> MessageSend receiver: ECController model: RefactoringBrowser classOrganizer: subject: AnObsoleteEvoPolygonMorph class So there appears to be a RefactoringBrowser which has classList nil, selectedEnvironment nil, etc, but which has classOrganizer with subject AnObsoleteEvoPolygonMorph. Is there a safe way to tidy this up please? ...Stan -- View this message in context: http://www.nabble.com/Tracking-down-an-obsolete-class-from-a-RefactoringBro… Sent from the Squeak - Beginners mailing list archive at Nabble.com.

Understanding "self"
by Andy Burnett 30 Jan '08

30 Jan '08

I am working through the SBE book ( which is really very good) and I have been experimenting with using self in blocks. In simple terms I am doing something like: " within the initialisation of an object" aVar := AnotherObj new aVar setBlockTo: [Transcript show: self] Then I had a method in the first object which asked the second object to show the value of its block. What I was expecting was for self to be defined in terms of the object it was assigned to ie the second object. However it actually returns tv details of the object the block was coded in Somehow I don't think I am explaining myself very well. But what I want to know is how to think about self. Will it always point to the object in which the method was actually written? Thanks AB

29 Jan '08

I know this is a really easy question(i think), but I just ran my squeak image on a very large resolution computer, and i had things in the corner of the world, and when i can back to my computer, with a smaller resolution, they are gone. How do i get them back?
