The gtk:aspect-frame widget 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. The gtk:aspect-frame class derives from the gtk:frame class, so it can draw a label and a frame around the child. The frame will be "shrink-wrapped" to the size of the child. The gtk:aspect-frame implementation uses a CSS node with name frame.
