Method GTK2.TreeSortable()->set_default_sort_func()

Method set_default_sort_func

GTK2.TreeSortable set_default_sort_func(function(:void) f, mixed user_data)

Description

Sets the default comparison function used when sorting to be f. If the current sort column id of this sortable is GTK2.TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID, then the model will sort using this function.

if f is 0, then there will be no default comparison function. This means 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 this sortable is GTK2.TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID, the model will be unsorted.
