LayoutChildRef

public struct LayoutChildRef : LayoutChildProtocol, GWeakCapturing

GtkLayoutChild is the base class for objects that are meant to hold layout properties.

If a GtkLayoutManager has per-child properties, like their packing type, or the horizontal and vertical span, or the icon name, then the layout manager should use a GtkLayoutChild implementation to store those properties.

A GtkLayoutChild instance is only ever valid while a widget is part of a layout.

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

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

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