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:



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.




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.




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 GtkWindow which
will be used as tooltip window. This works as follows:



Set GtkWidget:has-tooltip and connect to GtkWidget::query-tooltip as
before.




Use gtk_widget_set_tooltip_window() to set a GtkWindow created by you as
tooltip window.




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.
