### Nemo.PropertyPageProvider Example

    import hashlib
    import urllib

    from gi.repository import Nemo, GObject, Gtk

    class ColumnExtension(GObject.GObject, Nemo.PropertyPageProvider):
        def __init__(self):
            pass

        def get_property_pages(self, files):
            if len(files) != 1:
                return

            file = files[0]
            if file.get_uri_scheme() != 'file':
                return

            if file.is_directory():
                return

            filename = urllib.unquote(file.get_uri()[7:])

            self.property_label = Gtk.Label('MD5Sum')
            self.property_label.show()

            self.hbox = Gtk.HBox(homogeneous=False, spacing=0)
            self.hbox.show()

            label = Gtk.Label('MD5Sum:')
            label.show()
            self.hbox.pack_start(label, False, False, 0)

            self.value_label = Gtk.Label()
            self.hbox.pack_start(self.value_label, False, False, 0)

            md5sum = hashlib.md5()
            with open(filename,'rb') as f:
                for chunk in iter(lambda: f.read(8192), ''):
                    md5sum.update(chunk)
            f.close()

            self.value_label.set_text(md5sum.hexdigest())
            self.value_label.show()

            return Nemo.PropertyPage(name="NemoPython::md5_sum",
                                         label=self.property_label,
                                         page=self.hbox),

## Passive Methods

### Nemo.PropertyPageProvider.get_pages

                get_pages

`files` :

- a list of `Nemo.FileInfo` objects.

Returns :

- a list of `Nemo.PropertyPage` objects

This function is called by Nemo when it wants property page items from the extension. It is called in the main thread before a property page is shown, so it should return quickly.
