TreeSortableT

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

Functions

addOnSortColumnChanged
gulong addOnSortColumnChanged(void delegate(TreeSortableIF) dlg, ConnectFlags connectFlags)

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.

getSortColumnId
bool getSortColumnId(int sortColumnId, GtkSortType order)

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.

getTreeSortableStruct
GtkTreeSortable* getTreeSortableStruct(bool transferOwnership)

Get the main Gtk struct

hasDefaultSortFunc
bool hasDefaultSortFunc()

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.

setDefaultSortFunc
void setDefaultSortFunc(GtkTreeIterCompareFunc sortFunc, void* userData, GDestroyNotify destroy)

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.

setSortColumnId
void setSortColumnId(int sortColumnId, GtkSortType order)

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

setSortFunc
void setSortFunc(int sortColumnId, GtkTreeIterCompareFunc sortFunc, void* userData, GDestroyNotify destroy)

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.

sortColumnChanged
void sortColumnChanged()

Emits a sort-column-changed signal on sortable.
