Description

Many native APIs will have a concept of object properties or attributes. These can be exposed via the EggDBusProperties interface. The available properties and whether they are writable can be determined by using the EggDBusIntrospectable interface.

Sets the value of the property with name property_name on the interface with name interface_name to value.

This function asynchronously invokes the Set() method on the org.freedesktop.DBus.Properties interface on the object represented by instance. When the reply is ready, callback will be called (on the main thread). You can then call egg_dbus_properties_set_finish() to get the result. See egg_dbus_properties_set_sync() for the synchronous version of this function.
