Hello all,
I've been interested to read about some of the activities of the Documentation team, as I've recently been trying to work out how to build a GUI application in Squeak.
To that end, I've built a sample image viewer application, heavily annotated, to keep a record of my understanding of the following areas:
- Morphic layout
- Use of Models and Pluggable Morphs
- Interacting with the filesystem
- Launching and managing background processes
Cool. That heavily commented SampleImageViewerMorph>>initialize is especially useful
The code is attached, and can also be found at http://www.squeaksource.com/SampleImageViewer.html
I'd appreciate it if anyone could spare some time to have a look at this sample and see if I'm making any obvious mistakes (especially my termination of processes, which I suspect isn't very robust), or if the 'squeakiness' of the code could be improved.
I am not sure, but every time I hit enter in the dir box, or click the main panel, I get a debug window. What Squeak version is this made for? I am using 3.8. A quick question: is the correct way to run this program: SampleImageViewerMorph new openInWorld
If anyone from the Documentation team is building a repository of sample code for beginners, I'd be happy to incorporate this application into such a repository.
We have not considered a code repository, but this morph is quite simple, and may be useful in a tutorial. I might incorporate it into my beginner's tutorial: http://minnow.cc.gatech.edu/squeak/5869
