Exported subordinate children:

Unless the resources are already defined in PtNumeric, the PtNumeric class uses the resources of its exported subordinate child, PtUpDown.

The PtNumeric class "inherits" all the resources of its exported subordinate child. Where PtNumeric and its exported subordinate child both define resources having the same name, the resource defined in PtNumeric takes precedence.

Inherited resources:

If the widget modifies an inherited resource, the "Default override" column indicates the new value. This modification affects any subclasses of the widget.
