+ * @class KBusyIndicatorWidget kbusyindicatorwidget.h KBusyIndicatorWidget
+ *
+ * @brief Rotating spinning icon to indicate busyness
+ *
+ * When you need to communicate to the user that your application is busy with
+ * something you'll want to use a KBusyIndicatorWidget to display an infinitely
+ * spinnning indicator icon.
+ *
+ * A way of using this widget is to combine it with a QLabel to construct a
+ * status line:
+ *
+ * ```
+ * auto layout = new QHBoxLayout;
+ * layout->addWidget(new KBusyIndicatorWidget);
+ * layout->addWidget(new QLabel(QStringLiteral("Watering the flowers...")));
+ * ```
+ *
+ * @image html kbusyindicatorwidget.png "KBusyIndicatorWidget with label"
+ *
+ * KBusyIndicatorWidget is set apart from KPixmapSequenceWidget in that it
+ * does not render a pixmap sequence but rather animates a scaled Icon.
+ * It can support multiple semi-arbitrary sizes and quality is only limited
+ * by the resolution of available icons. It is also easier to use as its use
+ * is more specific.
+ *
+ * @since 5.61.0
