Is your code available somewhere on SqueakSource ? Laurent. On Fri, Jun 17, 2011 at 5:26 AM, Tony Giaccone <tony@giaccone.org> wrote:
Every time I look at smalltalk, I'm blown away with how cool it is to work with and each time I try to get started, my efforts are stymied pretty quickly.
I understand message passing, and I understand the basics of the syntax, but I'm having a very hard time understanding how to use the class libraries.
I am trying to build a very small app. A simple data editor and browser. I've been able to follow an example in the code (simple grid example).
I can now display my objects in a window, with four of the attributes listed in the editor.
Now I can select an time and change it in place in the list editor but that change doesn't make it into the "database" (my ordered collection).
It is not clear to me at all how to select a line in a MorphTreeMorph. Nor how to save the change when the user tabs out or hits return.
Any help would be appreciated.
