gtk:file-chooser-create-folders (object)

object -- a gtk:file-chooser widget
setting -- true if the New Folder button should be displayed

The accessor for the create-folders slot gets or sets whether the file chooser will offer to create new folders. This is only relevant if the action of the file chooser is not set to be in :open mode. The gtk:file-chooser implementation is deprecated since 4.10. Use the gtk:file-dialog object instead.
