void gtk_entry_completion_set_minimum_key_length ( GtkEntryCompletion* completion, int length )
Requires the length of the search key for
completion to be at least
This is useful for long lists, where completing using a small key takes a lot of time and will come up with meaningless results anyway (ie, a too large dataset).
Deprecated since: 4.10
GtkEntryCompletion will be removed in GTK 5.
