Rust program showing how to use gkt4/ColumnView type to display mutiple columns in a gtk window.
I couldn't find a good example showing how to do this so I wrote one.
- Written in Rust.
- Tested on Linux and Windows 10
- Shows 2 columns
- Shows 100000 rows
- ListModelExt implemented by StringList containing StringObject(s) - both included in GTK4
Please let me know if I got anything wrong or left anything out.
