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?

problems pulling data from a url..
by sergio_101 05 Apr '10

05 Apr '10

i am currently using HTTPSocket to pull data from a url... looks like this: | data | data := String fromByteArray: (HTTPSocket httpGet: anUrl). i end up with a string that has my desired data (a JSON string), but, it's preceeded by this: 'a RWBinaryOrTextStream ' '<here is the stuff i need>' ' ' i am trying to lop off the first part by doing: jsonData := dataString replaceAll: 'RWBinaryOrTextStream' with: 'test'. just to see if i can touch the string.. but no matter what i do, i can't get any parts of the string to be raplaced.. it almost looks like there are three strings in there.. the RWBinaryOrTextStream one, the one i need, and an empty one.. is there a better way to pull a url? thanks! -- ---- peace, sergio photographer, journalist, visionary http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

My goal is to teach high school students how to construct simple, focused apps using morphs. In tcl/tk I find list boxes useful building blocks and am supprised not to find any on the Objects tab. Installing from SqueakMap fails because Maui breaks FileList. Installing from Montecello fails because what I see looks nothing like what the wiki page describes, and the load generates a long list of warnings. =-=-=-=-= On Fri, 26 Mar 2010 12:47:53 -0700 (PDT) Jerome Peace <peace_the_dreamer(a)yahoo.com> wrote: >From your description it sounds like you are trying to mimic what a pdf > reader does (or > what a web page does) with a index table of contents in the left frame and > the file contents > or page in the right frame.

Best list box morph
by Gary Dunn 26 Mar '10

26 Mar '10

I am developing techniques for building useful little apps from morphic building blocks, typically with a BookMorph or StackMorph as the foundation, and with a minimum of old fashioned programing. My goal is to teach this to high school students. One basic structure I want is a browser, like our System Browser. Basically a list box on the left and one or more text fields to the right; clicking on an entry in the list box displays the corresponding data. So far I have not found a useful list box morph. The EToyHierarchicalText morph comes close, but entry editing is too minimal. The LazyListMorph nevers appears. Is there a preferred or typical way this is done? -- Gary Dunn, Honolulu osp(a)aloha.com http://openslate.net/ http://e9erust.blogspot.com/ Sent from Slate001

displaying picture from local path
by Michael Delache 24 Mar '10

24 Mar '10

Hi, I tried to display a picture (located in my computer) in a web application using a 'html image' block but it didn't worked. I tried the same code with a picture located on a web server and it worked. What is the difference between the two situations? How could I get what I want? Thanks
