+/**
+ * @class KToolTipWidget ktooltipwidget.h KToolTipWidget
+ *
+ * @brief A tooltip that contains a QWidget.
+ *
+ * This widget allows to show a tooltip that contains another widget.
+ * If you only need to show text inside the tooltip, just use QWidget::setToolTip();
+ *
+ * To show the tooltip, you need to choose a position on the screen and also pass a
+ * transient parent window (recommended on X11 and required on Wayland).
+ * Use showAt() if you want to show the tooltip from a specific point.
+ * Use showUnder() if you want to show it under a given rectangle.
+ *
+ * You can use a single instance of this class to show as many tooltips as you want.
+ *
+ * The tooltip does not take ownership of the content widget if the latter already
+ * has a parent. While the tooltip is set as parent of the widget (by the layout),
+ * the old parent is restored when the widget is replaced by another widget
+ * and also when the tooltip is deleted.
+ *
+ * @since 5.30
+ * @author Elvis Angelaccio <elvis.angelaccio@kde.org>
