+// A specialized container, which is a cross between a GtkBin and a
+// GtkFixed. This container dervies from GtkBin and the implementation of
+// gtk_container_add() is the same: only one GtkWidget can be added through
+// that interface. The GtkBin portion contains normal content and is given the
+// same allocation that this container has.
+//
+// In addition, any number of widgets can be added through the
+// gtk_floating_container_add_floating() method, which provides functionality
+// similar to a GtkFixed. Unlike a GtkFixed, coordinates are not set when you
+// gtk_fixed_put(). The location of the floating widgets is determined while
+// running the "set-floating-position" signal, which is emitted during this
+// container's "size-allocate" handler.
+//
+// The "set-floating-position" signal is (semi-)mandatory if you want widgets
+// placed anywhere other than the origin and should have the following
+// signature:
+//
+//   void (*set_floating_position)(GtkFloatingContainer* container,
+//                                 GtkAllocation* allocation,
+//                                 gpointer userdata);
+//
+// Your handler should, for each floating widget, set the "x" and "y" child
+// properties.
