+ * of one. Refcount will not be further increased when
+ * it is passed to wxVariant. This simulates old common

+ * If you create wxVariantData for other reasons than passing

* TODO: in order to replace wxPropertyValue, we would need
* to consider adding constructors that take pointers to C++ variables,
* or removing that functionality from the wxProperty library.
