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 the default handler for the query_tooltip signal will take care of displaying the tooltip.
Note that some platforms have limitations on the length of tooltips that they allow on status icons, e.g. Windows only shows the first 64 characters.
