gtk:file-chooser-select-multiple (object)

object -- a gtk:file-chooser widget
setting -- true if multiple files can be selected

The accessor for the select-multiple slot gets or sets whether multiple files can be selected in the file selector. This is only relevant if the action of the file chooser is set to be in :open or :select-folder mode. The gtk:file-chooser implementation is deprecated since 4.10. Use the gtk:file-dialog object instead.
