+        and columns by default, or rows only if GetFlexibleDirection() is @c
+        wxVERTICAL or columns only if it is @c wxHORIZONTAL) is always governed

-            - wxFLEX_GROWMODE_SPECIFIED: Sizer honors growable columns/rows set with

-              to minimum sizes of columns or rows (this is the default value).
