TreeSortableT

#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.

template TreeSortableT () {

bool getSortColumnId(int sortColumnId, gtk.types.SortType order);

bool hasDefaultSortFunc();

void setDefaultSortFunc(gtk.types.TreeIterCompareFunc sortFunc);

void setSortColumnId(int sortColumnId, gtk.types.SortType order);

Functions

connectSortColumnChanged gulong connectSortColumnChanged(T callback, Flag!"After" after): Connect to SortColumnChanged signal.
getSortColumnId bool getSortColumnId(int sortColumnId, gtk.types.SortType 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.types.TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID or gtk.types.TREE_SORTABLE_UNSORTED_SORT_COLUMN_ID.
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(gtk.types.TreeIterCompareFunc sortFunc): Sets the default comparison function used when sorting to be sort_func. If the current sort column id of sortable is gtk.types.TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID, then the model will sort using this function.
setSortColumnId void setSortColumnId(int sortColumnId, gtk.types.SortType 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, gtk.types.TreeIterCompareFunc sortFunc): 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.
