GDBusInterfaceVTable

Virtual table for handling properties and method calls for a D-Bus interface.

Since 2.38, if you want to handle getting/setting D-Bus properties asynchronously, give %NULL as your get_property() or set_property() function. The D-Bus call will be directed to your @method_call function, with the provided @interface_name set to "org.freedesktop.DBus.Properties".

The usual checks on the validity of the calls is performed. For Get calls, an error is automatically returned if the property does not exist or the permissions do not allow access. The same checks are performed for Set calls, and the provided value is also checked for being the correct type.

For both Get and Set calls, the #GDBusMethodInvocation passed to the @method_call handler can be queried with g_dbus_method_invocation_get_property_info() to get a pointer to the #GDBusPropertyInfo of the property.

If you have readable properties specified in your interface info, you must ensure that you either provide a non-%NULL @get_property() function or provide implementations of both the Get and GetAll methods on org.freedesktop.DBus.Properties interface in your @method_call function. Note that the required return type of the Get call is (v), not the type of the property. GetAll expects a return value of type a{sv}.

If you have writable properties specified in your interface info, you must ensure that you either provide a non-%NULL @set_property() function or provide an implementation of the Set call. If implementing the call, you must return the value of type %G_VARIANT_TYPE_UNIT.
