GIDL is not the same as GIR (which is the XML format used by GObject
Introspection). You could use GIR metadata to achieve what you're
after:
MyObject.object_list type="weak GLib.SList<AnotherObject>"
If you really did mean GIDL you could do something like this:
MyObject.object_list type_arguments="AnotherObject"
But if you're really using G-I it would be best to add the proper
annotations to your C code so other G-I consumers can take advantage. I
believe something like this should work:
/**
* MyObject:
* @object_list: (element-type AnotherObject): list of objects
*
* Description of MyObject.
*/
typedef struct _MyObject {
GSList* object_list;
} MyObject;
