|

* >>> 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.
