/**
* gtk_tool_button_set_label:
* @button: a #GtkToolButton
* @label: (allow-none): a string that will be used as label, or %NULL.
*
* Sets @label as the label used for the tool button. The "label" property
* only has an effect if not overridden by a non-%NULL "label_widget" property.
* If both the "label_widget" and "label" properties are %NULL, the label
* is determined by the "stock_id" property. If the "stock_id" property is also
* %NULL, @button will not have a label.
*
* Since: 2.4
