  27  * @short_description: A special toolbar to be used with HildonAppView
  28  * @see_also: #HildonAppView
  29  *
  30  * HildonFindToolbar is a predefined toolbar for text searching purpose.
  31  * It contains a GtkListStore which has the text items that the user has
  32  * searched. But once the application is terminated, or HildonFindToolbar
  33  * is trashed. Programmer is responsible for getting the GtkListStore through
  34  * property "list", if he/she wants to use the information in the future.
  35  * And through the same property, programmer is able to set the GtkListStore.
  36  * Note, once the search button is pressed, string in the GtkComboxEntry is
  37  * automatically added to the existing model, unless it is empty.
