27 * @short_description: A single-child container widget that precedes the
28 * contained widget with a field label and an optional icon
30 * #HildonCaption is a single-child container widget that precedes the
31 * contained widget with a field label and an optional icon. It allows
32 * grouping of several controls together. When a captioned widget has focus,
33 * both widget and caption label are displayed with active focus.
