pub fn set_font(&mut self, font: &'static dyn FontMetrics)

Assign the font used to render entry names (FONT-00 §5); resolves to FONT_6X10 when unset.

pub fn on_file_selected(self, cb: impl FnMut(&str) + 'static) -> Self

Set the callback invoked when a .wav file is double-tapped. The argument is the full path to the selected file.
