    /// [`WidgetExt::set_tooltip_markup()`][crate::prelude::WidgetExt::set_tooltip_markup()] without
    /// any explicit tooltip object.
    ///
    /// When you need a tooltip with a little more fancy contents,
    /// like adding an image, or you want the tooltip to have different
    /// contents per [`TreeView`][crate::TreeView] row or cell, you will have to do a
    /// little more work:
    ///
    /// - Set the [`has-tooltip`][struct@crate::Widget#has-tooltip] property to [`true`].
    ///   This will make GTK monitor the widget for motion and related events
    ///   which are needed to determine when and where to show a tooltip.
    ///
    /// - Connect to the [`query-tooltip`][struct@crate::Widget#query-tooltip] signal.
    ///   This signal will be emitted when a tooltip is supposed to be shown.
    ///   One of the arguments passed to the signal handler is a [`Tooltip`][crate::Tooltip]
    ///   object. This is the object that we are about to display as a tooltip,
    ///   and can be manipulated in your callback using functions like
    ///   [`set_icon()`][Self::set_icon()]. There are functions for setting
    ///   the tooltip’s markup, setting an image from a named icon, or even
    ///   putting in a custom widget.
    ///
    /// - Return [`true`] from your ::query-tooltip handler. This causes the tooltip
    ///   to be show. If you return [`false`], it will not be shown.
