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().

id for the added choice
label

options
ids for the options of the choice, or None for a boolean choice
