ColumnViewColumn.this

Creates a new gtk.column_view_column.ColumnViewColumn that uses the given factory for mapping items to widgets.

You most likely want to call gtk.column_view.ColumnView.appendColumn next.

The function takes ownership of the argument, so you can write code like:

column = gtk_column_view_column_new (_("Name"),
  gtk_builder_list_item_factory_new_from_resource ("/name.ui"));
