GtkFlowBoxset_sort_func

void
gtk_flow_box_set_sort_func (
  GtkFlowBox* box,
  GtkFlowBoxSortFunc sort_func,
  gpointer user_data,
  GDestroyNotify destroy
)

By setting a sort function on the box, one can dynamically reorder the children of the box, based on the contents of the children.

The sort_func will be called for each child after the call, and will continue to be called each time a child changes (via gtk_flow_box_child_changed()) and when gtk_flow_box_invalidate_sort() is called.

Note that using a sort function is incompatible with using a model (see gtk_flow_box_bind_model()).
