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?

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

Actually that was (of course!) just an off-the-cuff pseudocode I posted and not a copy-and-paste. My email client does not have a syntax checker, unfortunately :) #streamContents: indeed seems to be what I need. - TimJ

(drawing) doesNotUnderstand fillRectangle
by Filip Malczak 26 Nov '08

26 Nov '08

I continue working on my stave-and-tabulature program(some older, but not very older version is in one of last mails). And I still cant really draw my object. Its rectangle (subclass of RectangleMorph) with submorph StringMorph - just a easy button. Here I have its drawOn: drawOn: aCanvas |label| super drawOn: aCanvas. label:=self findA: StringMorph. label center: self center. label drawOn: self. When I try to but:=TempoButton new. but drawOn: World. in Workspace and doIt, I have debugger with: PasteUpMorph(Object)>>doesNotUnderstand: #fillRectangle:fillStyle:borderStyle So I think it goes up in superclass chain, and finds out drawOn: of Morph, but for some reason it doesnt really understands it. Why? -- Pozdrawiam: Filip GG: 2486889 mail: filet00(a)gmail.com

I want to load a package from SqueakMap. When I select open...SqueakMap Package Loader, I get the following. In the SMSqueakMap>>categories method, the instance variable "objects" is nil and it's trying to send select: to that. Any idea what's going on? --- Mark Volkmann
