gtk:filter-strictness (filter)

filter -- a gtk:filter object

The gtk:filter-match value with the strictness of filter.

Gets the known strictness of the filter. If the strictness is not known, the :match-some value is returned. The value may change after emission of the "changed" signal. This function is meant purely for optimization purposes, filters can choose to omit implementing it, but the gtk:filter-list-model class uses it.
