TreeSortableIF

#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.

interface TreeSortableIF {

GtkTreeSortable* getTreeSortableStruct();

void* getStruct();

bool getSortColumnId(int sortColumnId, GtkSortType order);

bool hasDefaultSortFunc();

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

void setSortColumnId(int sortColumnId, GtkSortType order);

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

void sortColumnChanged();

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

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.
getStruct void* getStruct(): the main Gtk struct as a void*
getTreeSortableStruct GtkTreeSortable* getTreeSortableStruct(): 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 #GtkTreeSortable::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 #GtkTreeSortable::sort-column-changed signal on @sortable.
