CustomLayoutRef

public struct CustomLayoutRef : CustomLayoutProtocol, GWeakCapturing

GtkCustomLayout uses closures for size negotiation.

A GtkCustomLayoutuses closures matching to the old GtkWidget virtual functions for size negotiation, as a convenience API to ease the porting towards the corresponding `GtkLayoutManager virtual functions.

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

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

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