Because it's an object, not a type. :-)

+typedef struct QType {
+    qtype_code code;
+    void (*destroy)(struct QObject *);
+} QType;

...

+/* Get the QObject part of a type */
+#define QOBJECT(obj) (&obj->base)
+
+/* High-level interface for qobject_incref() */
+#define QINCREF(qtype)      \
+    assert(qtype != NULL);  \
+    qobject_incref(QOBJECT(qtype))
