ListItemRef
public struct ListItemRef : ListItemProtocol, GWeakCapturing
GtkListItem
is used by list widgets to represent items in a GListModel
.
The GtkListItem
s 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
].
GtkListItem
s exist in 2 stages:
The unbound stage where the listitem is not currently connected to an item in the list. In that case, the [property
Gtk.ListItem:item
] property is set tonil
.The bound stage where the listitem references an item from the list. The [property
Gtk.ListItem:item
] property is notnil
.
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.

Untyped pointer to the underlying `GtkListItem` instance.
For type-safe access, use the generated, typed pointer
list_item_ptr
property instead.Declaration
