Description GtkToolButtons are GtkToolItems containing buttons. Use gtk_tool_button_new() to create a new GtkToolButton. Use gtk_tool_button_new_with_stock() to create a GtkToolButton containing a stock item. The label of a GtkToolButton is determined by the properties "label-widget", "label", and "stock-id". If "label-widget" is non-NULL, then that widget is used as the label. Otherwise, if "label" is non-NULL, that string is used as the label. Otherwise, if "stock-id" is non-NULL, the label is determined by the stock item. Otherwise, the button does not have a label. The icon of a GtkToolButton is determined by the properties "icon-widget" and "stock-id". If "icon-widget" is non-NULL, then that widget is used as the icon. Otherwise, if "stock-id" is non-NULL, the icon is determined by the stock item. Otherwise, the button does not have a icon.
