ListItemRef

public struct ListItemRef : ListItemProtocol, GWeakCapturing

GtkListItem is used by list widgets to represent items in a GListModel.

The GtkListItems are managed by the list widget (with its factory) and cannot be created by applications, but they need to be populated by application code. This is done by calling [methodGtk.ListItem.set_child].

GtkListItems exist in 2 stages:

  1. The unbound stage where the listitem is not currently connected to an item in the list. In that case, the [propertyGtk.ListItem:item] property is set to nil.

  2. The bound stage where the listitem references an item from the list. The [propertyGtk.ListItem:item] property is not nil.

The ListItemRef type acts as a lightweight Swift reference to an underlying GtkListItem instance. It exposes methods that can operate on this data type through ListItemProtocol conformance. Use ListItemRef only as an unowned reference to an existing GtkListItem instance.

  • ptr 
    Untyped pointer to the underlying `GtkListItem` instance.

    For type-safe access, use the generated, typed pointer list_item_ptr property instead.
