* >>> 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.
