Nautilus.ColumnProvider: nautilus-python Reference Manual

Nautilus.ColumnProvider

Nautilus.ColumnProvider — Nautilus.ColumnProvider Reference

Synopsis

 Nautilus.ColumnProvider {
  get_columns();
}

Description

If subclassed, Nautilus will request a list of Nautilus.Column objects, which are then displayed when the user is in List mode.

An extension sub-classing Nautilus.ColumnProvider will almost always want to sub-class Nautilus.InfoProvider as well, since that is how an extension provides information for each item in a directory listing.
