PointerInterface
public class ColumnViewSorter extends Sorter
Sorts [class@Gtk.ColumnView] columns.

The sorter returned by [method@Gtk.ColumnView.get_sorter] is
a `GtkColumnViewSorter`.

In column views, sorting can be configured by associating
sorters with columns, and users can invert sort order by clicking
on column headers. The API of `GtkColumnViewSorter` is designed
to allow saving and restoring this configuration.

If you are only interested in the primary sort column (i.e. the
column where a sort indicator is shown in the header), then
you can just look at [property@Gtk.ColumnViewSorter:primary-sort-column]
and [property@Gtk.ColumnViewSorter:primary-sort-order].

If you want to store the full sort configuration, including
secondary sort columns that are used for tie breaking, then
you can use [method@Gtk.ColumnViewSorter.get_nth_sort_column].
To get notified about changes, use [signal@Gtk.Sorter::changed].

To restore a saved sort configuration on a `GtkColumnView`,
use code like:

```
sorter = gtk_column_view_get_sorter (view);
for (i = gtk_column_view_sorter_get_n_sort_columns (sorter) - 1; i >= 0; i--)
{
column = gtk_column_view_sorter_get_nth_sort_column (sorter, i, &order);
gtk_column_view_sort_by_column (view, column, order);
}
```

  • Methodendetails

    • getClassHandler

      public static ClassHandler getClassHandler()

    • getNSortColumns

      public int getNSortColumns()
      Returns the number of columns by which the sorter sorts.

      If the sorter of the primary sort column does not determine
      a total order, then the secondary sorters are consulted to
      break the ties.

      Use the [signal@Gtk.Sorter::changed] signal to get notified
      when the number of sort columns changes.
      Gibt zurück:
      the number of sort columns

    • getNthSortColumn

      public ColumnViewColumn getNthSortColumn(int position, @Nonnull Int sort_order)
      Gets the @position'th sort column and its associated sort order.

      Use the [signal@Gtk.Sorter::changed] signal to get notified
      when sort columns change.
      Parameter:
      position - the position of the sort column to retrieve (0 for the primary sort column)
      sort_order - return location for the sort order
      Gibt zurück:
      the @positions sort column

    • getPrimarySortColumn

      public ColumnViewColumn getPrimarySortColumn()
      Returns the primary sort column.

      The primary sort column is the one that displays the triangle
      in a column view header.
      Gibt zurück:
      the primary sort column

    • getPrimarySortOrder

      public int getPrimarySortOrder()
      Returns the primary sort order.

      The primary sort order determines whether the triangle displayed
      in the column view header of the primary sort column points upwards
      or downwards.

      If there is no primary sort column, then this function returns
      `GTK_SORT_ASCENDING`.
      Gibt zurück:
      the primary sort order
