gtk:column-view-column-id (object)

object -- a gtk:column-view-column object
id -- a string for the ID to use for this column

The accessor for the id slot of the gtk:column-view-column class gets or sets the ID for the column. GTK makes no use of this, but applications can use it when storing column view configuration. It is up to callers to ensure uniqueness of IDs.
