public string tooltip_text { owned get; set; }

Sets the text of tooltip to be the given string.

Also see set_text.

This is a convenience property which will take care of getting the tooltip shown if the given string is not null : has_tooltip will automatically be set to true and there will be taken care of query_tooltip in the default signal handler.

Note that if both tooltip_text and tooltip_markup are set, the last one wins.
