Virtual Method

GtkTreeSortableset_default_sort_func

Declaration [src]

void
set_default_sort_func (
  GtkTreeSortable* sortable,
  GtkTreeIterCompareFunc sort_func,
  gpointer user_data,
  GDestroyNotify destroy
)

Description [src]

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.

If sort_func is NULL, then there will be no default comparison function. This means that once the model has been sorted, it can’t go back to the default state. In this case, when the current sort column id of sortable is GTK_TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID, the model will be unsorted.

Type: GtkTreeIterCompareFunc

user_data

Type: gpointer

User data to pass to sort_func, or NULL.

The argument can be NULL.

The data is owned by the caller of the method.

Type: GDestroyNotify

Destroy notifier of user_data, or NULL.
