GtkFlowBoxset_filter_func

void
gtk_flow_box_set_filter_func (
  GtkFlowBox* box,
  GtkFlowBoxFilterFunc filter_func,
  gpointer user_data,
  GDestroyNotify destroy
)

By setting a filter function on the box one can decide dynamically which of the children to show.

For instance, to implement a search function that only shows the children matching the search terms.

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

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