choose
open fun choose(parent: Window? = null, cancellable: <Error class: unknown class>? = null, callback: <Error class: unknown class>?)(source)
This function shows the alert to the user.
The @callback will be called when the alert is dismissed. It should call method@Gtk.AlertDialog.choose_finish to obtain the result.
It is ok to pass NULL for the callback if the alert does not have more than one button. A simpler API for this case is method@Gtk.AlertDialog.show.
