I have what is quite acceptable as a grid using the SimpleGridExample.
I also have figured out that the way to find the selection is by asking the model, not the tree. I have spent the last two days working on building a model in small talk of the problem domain. WHen I'm writing brand new code, I feel like I'm reasonably productive. It's when I have to try and start figuring out how to interact with the class libraries that my productivity plummets. The problem is to understand the libraries you have to be able to read the code, because there is no documentation. But reading the code in Smalltalk mean you have to know the language, the idioms in the language and how to successfully use the tools. That's a lot of learning curve. I have a reasonable first pass of the model working well now. Not complete, but good enough to be able to start looking at how to implement the UI. The problem for me is finding the code examples to look at. I spent a fair amount of time searching through squeaksource. I've been spending hours looking over the few examples in Morphic-MorphTreeWidget-Examples I'm more than wiling to try and expand the pool of examples as I start to flesh out what I'm doing. The pharopod casts have been extremely helpful. Tony On Jun 18, 2011, at 2:49 AM, Stéphane Ducasse wrote: > I understand your frustration. > It is mine too.
