*
* >>> GtkStringList <<<
*
* GtkStringList is a list model that wraps an array of strings.
* The objects in the model are of type GtkStringObject
* and have a “string” property that can be used inside expressions.
* Use it where/when you would typically use a char*[], but need a list model.
*
* Every item in a model has a position (= unsigned integer)
* "factories" takes care of mapping the items of the model
* to widgets that can be shown in the view
* by creating a listitem for each item that is currently in use.
* List items are always GtkListItem instances. Widgets can be recycled.
*
* GtkStringList can only handle strings.
* It is backed by a dynamically allocated array.
* GListStore is backed by a balanced tree.
*
* GTK provides functionality to make lists look and behave like trees
* by using the GtkTreeListModel and the GtkTreeExpander widget.
*
* Widgets are styleable using GTK CSS. Use the .rich-list style class.
*
* GListModel is an interface that represents a mutable list of GObjects.
