    ///
    /// 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 `property::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 `signal::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 GtkTooltip 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.
    ///
    /// In the probably rare case where you want to have even more control over the
    /// tooltip that is about to be shown, you can set your own [`Window`][crate::Window] which
    /// will be used as tooltip window. This works as follows:
    ///
    /// - Set `property::Widget::has-tooltip` and connect to `signal::Widget::query-tooltip` as before.
    ///  Use [`WidgetExt::set_tooltip_window()`][crate::prelude::WidgetExt::set_tooltip_window()] to set a [`Window`][crate::Window] created by you as
    ///  tooltip window.
    ///
    /// - In the `signal::Widget::query-tooltip` callback you can access your window using
    ///  [`WidgetExt::tooltip_window()`][crate::prelude::WidgetExt::tooltip_window()] and manipulate as you wish. The semantics of
    ///  the return value are exactly as before, return [`true`] to show the window,
    ///  [`false`] to not show it.
