GtkFilterChange

enum Gtk.FilterChange

Describes changes in a filter in more detail and allows objects using the filter to optimize refiltering items.

If you are writing an implementation and are not sure which value to pass, GTK_FILTER_CHANGE_DIFFERENT is always a correct choice.

Name	Description
`GTK_FILTER_CHANGE_DIFFERENT`	The filter change cannot be described with any of the other enumeration values.
`GTK_FILTER_CHANGE_LESS_STRICT`	The filter is less strict than it was before: All items that it used to return `TRUE` for still return `TRUE`, others now may, too.
`GTK_FILTER_CHANGE_MORE_STRICT`	The filter is more strict than it was before: All items that it used to return `FALSE` for still return `FALSE`, others now may, too.
