Required Methods§

source

fn add_choice( &self, id: impl IntoGStr, label: impl IntoGStr, 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 response signal handler using FileChooserExt::choice().
