Description Daniel Elstner 2007-02-17 19:48:05 UTC 
It is not possible to use GValue with types that are registered dynamically via the GTypePlugin interface.  g_value_init() fails with the following messages:

(test-value-plugin:30681): GLib-GObject-WARNING **: can't peek value table for type `CustomBoxed' which is not currently referenced

(test-value-plugin:30681): GLib-GObject-WARNING **: gvalue.c:96: cannot initialize GValue with type `CustomBoxed', this type has no GTypeValueTable implementation

The documentation mentions that a dynamic type can be referenced with either g_type_class_ref() or g_type_create_instance().  Unfortunately, neither of these functions can be used with boxed types.

Test case

The attached test case dynamically registers a custom boxed type in order to demonstrate the bug.
Comment 2 Matthias Clasen 2008-11-29 03:16:08 UTC 
I think you are right. GType never calls complete_type_info for unclassed dynamic types. At least I don't see how and when. Tim, any advice on how to fix this ?

Any ideas?
