FileChooser.addChoice

void addChoice(string id, string label, string[] options = null, string[] optionLabels = null)

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 gtk.file_chooser.FileChooser.setChoice before the dialog is shown, and you can obtain the user-selected value in the gtk.dialog.Dialog.response signal handler using gtk.file_chooser.FileChooser.getChoice.

`id`	id for the added choice
`label`	user-visible label for the added choice
`options`	ids for the options of the choice, or null for a boolean choice
`optionLabels`	user-visible labels for the options, must be the same length as options
