Method set_rules_hint

  `GTK2.TreeView set_rules_hint(int setting)`

Description

  This function tells GTK2+ that the user interface for your application requires users to read across tree rows and associate cells with one another. By default, GTK2+ will then render the tree with alternating row colors. Do not use it just because you prefer the appearance of the ruled tree; that's a question for the theme. Some themes will draw tree rows in alternating colors even when rules are turned off, and users who prefer that appearance all the time can choose those themes. You should call this function only as a semantic hint to the theme engine that your tree makes alternating colors usefull from a functional standpoint (since it has lots of columns, generally).
