SpinnerProtocol

public protocol SpinnerProtocol : WidgetProtocol

A GtkSpinner widget displays an icon-size spinning animation. It is often used as an alternative to a GtkProgressBar for displaying indefinite activity, instead of actual progress.

To start the animation, use gtk_spinner_start(), to stop it use gtk_spinner_stop().

CSS nodes

GtkSpinner has a single CSS node with the name spinner. When the animation is active, the :checked pseudoclass is added to this node.

The SpinnerProtocol protocol exposes the methods and properties of an underlying GtkSpinner instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see Spinner. Alternatively, use SpinnerRef as a lighweight, unowned reference if you already have an instance you just want to use.
