fn add_choice(&self, id: &str, label: &str, options: &[(&str, &str)])

Adds a ‘choice’ to the file chooser.

This is typically implemented as a combobox or, for boolean choices, as a checkbutton. You can select a value using FileChooserExt::set_choice() before the dialog is shown, and you can obtain the user-selected value in the signal::Dialog::response signal handler using FileChooserExt::choice().
