|
* 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.
|
|
|
|
|
|
*
|
|
|
|
|
|
* implements GtkBuildable interface
|
|
|
|
|
|
* <item> are GObject instances; support “translatable”, “context” and “comments”
|
|
|
|
|
|
*
|
|
|
|
|
|
* <object class="GtkStringList">
|

* <items>

|
* <item translatable="yes">Factory</item>
|

|
|
|
|
|
|
* </object>
|
|
|
|
|
|
*
|
|
|
|
|
|
* 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.
