ContentSerializer

class ContentSerializer(**properties: Any)

Superclasses: Object

Implemented Interfaces: AsyncResult

A GdkContentSerializer is used to serialize content for inter-application data transfers.

The GdkContentSerializer transforms an object that is identified by a GType into a serialized form (i.e. a byte stream) that is identified by a mime type.

GTK provides serializers and deserializers for common data types such as text, colors, images or file lists. To register your own serialization functions, use content_register_serializer.

Also see ContentDeserializer.
