Interface

GtkTreeSortable

deprecated: 4.10 

Description [src] 

interface Gtk.TreeSortable : Gtk.TreeModel

The interface for sortable models used by GtkTreeView

GtkTreeSortable is an interface to be implemented by tree models which support sorting. The GtkTreeView uses the methods provided by this interface to sort the model.

Deprecated since: 4.10

There is no replacement for this interface. You should use GtkSortListModel to wrap your list model instead.

Prerequisite

In order to implement TreeSortable, your type must inherit fromGtkTreeModel.

Implementations

Instance methods

gtk_tree_sortable_get_sort_column_id

Fills in sort_column_id and order with the current sort column and the order. It returns TRUE unless the sort_column_id is GTK_TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID or GTK_TREE_SORTABLE_UNSORTED_SORT_COLUMN_ID.

deprecated: 4.10 

gtk_tree_sortable_has_default_sort_func

Returns TRUE if the model has a default sort function. This is used primarily by GtkTreeViewColumns in order to determine if a model can go back to the default state, or not.

deprecated: 4.10 

gtk_tree_sortable_set_default_sort_func

Sets the default comparison function used when sorting to be sort_func. If the current sort column id of sortable is GTK_TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID, then the model will sort using this function.

deprecated: 4.10 

gtk_tree_sortable_set_sort_column_id

Sets the current sort column to be sort_column_id. The sortable will resort itself to reflect this change, after emitting a GtkTreeSortable::sort-column-changed signal. sort_column_id may either be a regular column id, or one of the following special values:.

deprecated: 4.10 

gtk_tree_sortable_set_sort_func

Sets the comparison function used when sorting to be sort_func. If the current sort column id of sortable is the same as sort_column_id, then the model will sort using this function.

deprecated: 4.10 

gtk_tree_sortable_sort_column_changed

Emits a GtkTreeSortable::sort-column-changed signal on sortable.

deprecated: 4.10 

Signals

Gtk.TreeSortable::sort-column-changed

The ::sort-column-changed signal is emitted when the sort column or sort order of sortable is changed. The signal is emitted before the contents of sortable are resorted.

Virtual methods

Gtk.TreeSortable.get_sort_column_id
