AspectFrameRef

public struct AspectFrameRef : AspectFrameProtocol, GWeakCapturing

GtkAspectFrame preserves the aspect ratio of its child.

The frame can respect the aspect ratio of the child widget, or use its own aspect ratio.

CSS nodes

GtkAspectFrame uses a CSS node with name frame.

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

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

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