+\constfunc{bool}{IsFullySpecified}{\void}
+
+Returns \true if neither of the size object components is equal to $-1$, which
+is used as default for the size values in wxWidgets (hence the predefined
+\texttt{wxDefaultSize} has both of its components equal to $-1$).
+
+This method is typically used before calling
+\helpref{SetDefaults}{wxsizesetdefaults}.
