UI widget content includes reference information by which its own UI widget refers to a child UI widget, and a description of an initial-focus designation for designating which of its own UI widget and child UI widget will have initial focus. A self-UI widget is generated, a child UI widget associated with the self-UI widget is generated based upon the reference information, and a UI widget hierarchy is thus built. A path is followed from a root of the UI widget hierarchy to a child UI widget designated by the corresponding initial-focus designation information. When a UI widget for which a child UI widget has not been designated in the corresponding reference information is retrieved, it is determined that this UI widget is the UI widget having the initial focus.
