set_default_sort_func


Description:

public abstract void set_default_sort_func (owned TreeIterCompareFunc sort_func)

Sets the default comparison function used when sorting to be sort_func.

If the current sort column id of this 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 this is gtk_tree_sortable_default_sort_column_id, the model will be unsorted.

Parameters:

this

A TreeSortable

sort_func

The comparison function

destroy

Destroy notifier of user_data, or null

user_data

User data to pass to sort_func, or null
