Invokes @callback on each non-internal child of @container.
See gtk_container_forall() for details on what constitutes
an “internal” child. For all practical purposes, this function
should iterate over precisely those child widgets that were
added to the container by the application with explicit add()
calls.
It is permissible to remove the child from the @callback handler.
Most applications should use gtk_container_foreach(),
rather than gtk_container_forall().
