Nemo.ColumnProvider: nemo-python Reference Manual

Nemo.ColumnProvider

Nemo.ColumnProvider — Nemo.ColumnProvider Reference

Synopsis

 Nemo.ColumnProvider {
  get_columns();
}

Description

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

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

Example 2. Nemo.ColumnProvider Example

import os
import urllib

from gi.repository import Nemo, GObject

class ColumnExtension(GObject.GObject, Nemo.ColumnProvider, Nemo.InfoProvider):
    def __init__(self):
        pass
    
    def get_columns(self):
        return Nemo.Column(name="NemoPython::block_size_column",
                               attribute="block_size",
                               label="Block size",
                               description="Get the block size"),

    def update_file_info(self, file):
        if file.get_uri_scheme() != 'file':
            return
        
        filename = urllib.unquote(file.get_uri()[7:])
        
        file.add_string_attribute('block_size', str(os.stat(filename).st_blksize))
