At the moment I have this (using the rust bindings):
```rust
main_window.handle(move |_, event| match event {
fltk::enums::Event::KeyUp => {
match fltk::app::event_key() {
// TODO | F1
fltk::enums::Key::Help => sender.send(WindowAction::Help),
_ => {}
}
false
}
_ => false,
});
```
But I can't figure out what I need to do to detect F1.
I can't speak for the Rust bindings, but in C++ you would use 'FL_F+n'
for Fn where 'n' is a numeric value, hence F1 would be FL_F+1.
Key values are defined in FL/Enumerations.H, specifically here:
