gtk-container-forall (container func)

container -- a gtk-container widget
func -- a gtk-callback callback function which is passed as a callback

Invokes a function on each child of the container, including children that are considered "internal", implementation details of the container. "Internal" children generally were not added by the user of the container, but were added by the container implementation itself. Most applications should use the gtk-container-foreach function, rather than the gtk-container-forall function.
