+ * SECTION:gtktooltip
+ * @Short_description: Add tips to your widgets
+ * @Title: GtkTooltip
+ *
+ * Basic tooltips can be realized simply by using gtk_widget_set_tooltip_text()
+ * or 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:
+ * <itemizedlist>
+ * <listitem>
+ * <para>
+ * Set the #GtkWidget: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.
+ * </para>
+ * </listitem>
+ * <listitem>
+ * <para>
+ * Connect to the #GtkWidget::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 gtk_tooltip_set_icon(). There are functions for setting
+ * the tooltip's markup, setting an image from a stock icon, or even putting in
+ * a custom widget.
+ * </para>
+ * </listitem>
+ * <listitem>
+ * <para>
+ * Return %TRUE from your query-tooltip handler. This causes the tooltip to be
+ * show. If you return %FALSE, it will not be shown.
+ * </para>
+ * </listitem>
+ * </itemizedlist>
+ *
+ * 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 #GtkWindow which
+ * will be used as tooltip window. This works as follows:
+ * <itemizedlist>
+ * <listitem>
+ * <para>
+ * Set #GtkWidget:has-tooltip and connect to #GtkWidget::query-tooltip as
+ * before.
+ * </para>
+ * </listitem>
+ * <listitem>
+ * <para>
+ * Use gtk_widget_set_tooltip_window() to set a #GtkWindow created by you as
+ * tooltip window.
+ * </para>
+ * </listitem>
+ * <listitem>
+ * <para>
+ * In the #GtkWidget::query-tooltip callback you can access your window using
+ * gtk_widget_get_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.
+ * </para>
+ * </listitem>
+ * </itemizedlist>
