CustomFilterProtocol

public protocol CustomFilterProtocol : FilterProtocol

GtkCustomFilter determines whether to include items with a callback.

The CustomFilterProtocol protocol exposes the methods and properties of an underlying GtkCustomFilter instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see CustomFilter. Alternatively, use CustomFilterRef as a lighweight, unowned reference if you already have an instance you just want to use.

CustomFilter Class: CustomFilterProtocol extension (methods and fields)

  • Sets the function used for filtering items.

    If match_func is nil, the filter matches all items.

    If the filter func changes its filtering behavior, gtk_filter_changed() needs to be called.

    If a previous function was set, its user_destroy will be called now.

    Declaration

    Swift

    @inlinable
func setFilterFunc(matchFunc: GtkCustomFilterFunc? = nil, userData: gpointer! = nil, userDestroy: GDestroyNotify?)
