One of the things that would be really nice to have in the virtualised ListView and TreeView JavaFX controls, not to mention future controls like TableView, is multiple selection. Certain kinds of apps just can not exist without multiple selection in fact.
So, unsurprisingly, today I got an email from a user of JavaFX, who claims to be a fan of FX Experience (hi Keith!), who was needing multiple selection for his work. I didn’t actually think it could be done very easily (and one of my main jobs is working on these controls, so I should know), but I spent a bit of time looking into it, and it turns out that it’s actually quite possible, with a number of warnings and rough edges, and also the use of a little bit of unpublished API. As long as you’re promising to not tell anyone, I thought I’d share this code….but just with you, so shhh
