Tooltip

Object Hierarchy:

Description:

public class Tooltip : Object

Represents a widget tooltip.

Basic tooltips can be realized simply by using [method@Gtk.Widget.set_tooltip_text] or [method@Gtk.Widget.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 `GtkTreeView` row or cell, you will have to do a little more work:

Set the [property@Gtk.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@Gtk.Widget:GtkTooltip: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 [method@Gtk.Tooltip.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 GtkTooltip::query-tooltip handler. This causes the tooltip to be show. If you return false, it will not be shown.
