DrawingAreaClassRef

public struct DrawingAreaClassRef : DrawingAreaClassProtocol

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

ptr

Untyped pointer to the underlying `GtkDrawingAreaClass` instance.

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