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

How do I diff two images?
by Clinton Blackmore 02 Jun '10

02 Jun '10

Greetings. While I've programmed for some time, I am new to Squeak. I was wondering how I diff or compare two images that are largely similar (such as, say, Scratch vs Scratch For Second Life). In other environments, I'd run the source trees for each project/variation through a recursive diff tool -- Beyond Compare, Changes.app, Kompare, or even `diff` from the command line. How do I do something similar in Squeak? Cheers, Clinton Blackmore

It is a virtual machine suspended in time. It cannot be compared or diff-ed, AFAIK. Subbu

Thank you Bert and David for your replies. I won't look anymore for what is not there (yet). - Frans.

How can make a subclass WITH the method to initialize it through the Halo
by Frans van Dunné 25 May '10

25 May '10

Dear all, I've been searching and searching without any luck. What I want to do is the following: 1. Create a morph using the tools available in the flaps. Set the size, colour etc. 2. Then create a MyNewSubclass of that morph (I can do this using the red button of the halo) 3. Then pass on the MyMethod to initialize MyNewSubclass to look exaclty as what I have edited using the tools on screen. That last step I cannot find. I have tried inspecting and copying the list of variables, but that takes a lot of editing before it is usable. And I am sure this is possible, otherwise, why offer the tools? Thanks for you time, Frans.

Removing Squeak completely
by Stephen Ng 25 May '10

25 May '10

Hi! I tried out Squeak and now want to remove all traces of it from from OS-X Snow Leopard system. I deleted all the apps and the directories they were in. Now I still see that the icons for all my ".bundle" files still show the squeak "Lego" icon. How can I remove all traces of Squeak from my system completely? Thanks. Stephen Ng

[Newbies] Pre-Getting started info: Unicode, utf8, large memory need
by Charles Hixson 22 May '10

22 May '10

Squeak looks interesting, but before getting started I need 3 pieces of info: 1) How does one read&write utf8 files? 2) Can strings by indexed by chars, even if they are unicode rather than ascii? 3) What happens if you have more data than will fit into RAM? (For 3 "use a database" is an acceptable answer, but I'm hoping for something involving automatic paging.) (For 2 "use 4 bytes/char" is acceptable, but only if there's a good answer to 3.) I thought I could just look this up in the documentation, but it doesn't seem to address these points...at least not until you start being able to read the code in the browser fluently. These questions also don't seem to have been addressed in the mailing list before. (At least a search didn't find them.) An additional, but much less urgent, question is "How does one use Squeak on multiple cores of a multi-core processor?"

Box2D port to squeak...?
by Lawson English 18 May '10

18 May '10

I rummaged around the varioius lists but didn't find any mention. Has any tried or at least considered porting the Box2D physics engine to squeak? A Box2DMorph and B0x2DPasteUpMorph would be rather interesting, I think. Lawson

Accepting in workspace
by Garret Raziel 16 May '10

16 May '10

What happen if I write something in Workspace and them I hit "accept it"? Is it some kind of saving the content of workspace? And if so, where can I access it later? Garret Raziel
