-// A specialized container derived from GtkHBox, which can shrink or hide its
-// children one by one to fit into its width.
-//
-// Limitations of this container:
-// - All children should have the same pack type, otherwise they may be
-//   overlapped with each other.
-// - All children must be packed with expand == false and fill == false,
-//   otherwise they may be overlapped with each other.
-// - The visibility of a child is adjusted automatically according to the
-//   container's width. The child may not show or hide itself.
