Expand description

There is no replacement for this interface. You should use SortListModel to wrap your list model instead The interface for sortable models used by GtkTreeView

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

§Signals

§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.

TreeModel

§row-changed

This signal is emitted when a row in the model has changed.

§row-deleted

This signal is emitted when a row has been deleted.

Note that no iterator is passed to the signal handler, since the row is already deleted.

This should be called by models after a row has been removed. The location pointed to by @path should be the location that the row previously was at. It may not be a valid location anymore.

§row-has-child-toggled

This signal is emitted when a row has gotten the first child row or lost its last child row.

§row-inserted

This signal is emitted when a new row has been inserted in the model.

Note that the row may still be empty at this point, since it is a common pattern to first insert an empty row, and then fill it with the desired values.

§rows-reordered

This signal is emitted when the children of a node in the TreeModel have been reordered.

Note that this signal is not emitted when rows are reordered by DND, since this is implemented by removing and then reinserting the row.

👎Deprecated: Since 4.10
This signal is emitted when a row in the model has changed. Read more

fn connect_row_deleted<F: Fn(&Self, &TreePath) + 'static>( &self, f: F ) -> SignalHandlerId

👎Deprecated: Since 4.10
This signal is emitted when a row has been deleted. Read more

fn connect_row_has_child_toggled<F: Fn(&Self, &TreePath, &TreeIter) + 'static>( &self, f: F ) -> SignalHandlerId

👎Deprecated: Since 4.10
This signal is emitted when a row has gotten the first child row or lost its last child row. Read more

fn connect_row_inserted<F: Fn(&Self, &TreePath, &TreeIter) + 'static>( &self, f: F ) -> SignalHandlerId

👎Deprecated: Since 4.10

fn get<V: for<'b> FromValue<'b> + 'static>( &self, iter: &TreeIter, column: i32 ) -> V

👎Deprecated: Since 4.10
Similar to Self::get_value but panics if the value is of a different type. Gets the value of one or more cells in the row referenced by @iter. Read more

fn has_default_sort_func(&self) -> bool

👎Deprecated: Since 4.10
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. Read more

fn sort_column_changed(&self)

👎Deprecated: Since 4.10
Emits a GtkTreeSortable::sort-column-changed signal on @self. Read more

fn connect_sort_column_changed<F: Fn(&Self) + 'static>( &self, f: F ) -> SignalHandlerId

👎Deprecated: Since 4.10
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.

fn set_default_sort_func<F>(&self, sort_func: F)
where F: Fn(&Self, &TreeIter, &TreeIter) -> Ordering + 'static,

👎Deprecated: Since 4.10
Sets the default comparison function used when sorting to be @sort_func. If the current sort column id of @self is GTK_TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID, then the model will sort using this function. Read more

fn set_sort_func<F>(&self, sort_column_id: SortColumn, sort_func: F)
where F: Fn(&Self, &TreeIter, &TreeIter) -> Ordering + 'static,

👎Deprecated: Since 4.10
Sets the comparison function used when sorting to be @sort_func. If the current sort column id of @self is the same as @sort_column_id, then the model will sort using this function. Read more
source§

fn sort_column_id(&self) -> Option<(SortColumn, SortType)>

👎Deprecated: Since 4.10
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. Read more
source§

fn set_sort_column_id(&self, sort_column_id: SortColumn, order: SortType)

👎Deprecated: Since 4.10
Sets the current sort column to be @sort_column_id. The @self 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: Read more
