AspectFrameRef

public struct AspectFrameRef : AspectFrameProtocol, GWeakCapturing

The GtkAspectFrame is useful when you want pack a widget so that it can resize but always retains the same aspect ratio. For instance, one might be drawing a small preview of a larger image. GtkAspectFrame derives from GtkFrame, so it can draw a label and a frame around the child. The frame will be “shrink-wrapped” to the size of the child.

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.
