classTooltip : gobject.object.ObjectWrap

[gtk.tooltip.Tooltip] is an object representing a widget tooltip.

Basic tooltips can be realized simply by using [gtk.widget.Widget.setTooltipText] or [gtk.widget.Widget.setTooltipMarkup] 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 [gtk.tree_view.TreeView] 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::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 [gtk.tooltip.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 [gtk.tooltip.Tooltip.setIcon]. 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.
