+// A specialized container derived from GtkFixed, which expands the size of its
+// children to fill the container, in one or both directions. The usage of this
+// container is similar to GtkFixed.
+//
+// The "child-size-request" signal is optional, if you want to expand child
+// widgets to customized size other than the container's size. It should have
+// the following signature:
+//
+//   void (*child_size_request)(GtkExpandedContainer* container,
+//                              GtkWidget* child,
+//                              GtkRequisition* requisition);
+//
+// This signal is emitted for each child with the requisition set to the size of
+// the container. Your handler may adjust the value of the requisition. If the
+// width or height is set to -1, then that direction will not be expanded, and
+// the original size request of the child will be used.
