SnapshotRef

public struct SnapshotRef : SnapshotProtocol, GWeakCapturing

GtkSnapshot assists in creating GskRenderNodes for widgets.

It functions in a similar way to a cairo context, and maintains a stack of render nodes and their associated transformations.

The node at the top of the stack is the the one that gtk_snapshot_append_… functions operate on. Use the gtk_snapshot_push_… functions and gtk_snapshot_pop() to change the current node.

The typical way to obtain a GtkSnapshot object is as an argument to the [vfuncGtk.Widget.snapshot] vfunc. If you need to create your own GtkSnapshot, use [ctorGtk.Snapshot.new].

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

    Untyped pointer to the underlying `GtkSnapshot` instance.

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