39 * @Short_description: Add tips to your widgets
42 * Basic tooltips can be realized simply by using gtk_widget_set_tooltip_text()
43 * or gtk_widget_set_tooltip_markup() without any explicit tooltip object.
45 * When you need a tooltip with a little more fancy contents, like adding an
46 * image, or you want the tooltip to have different contents per #GtkTreeView
47 * row or cell, you will have to do a little more work:
51 * Set the #GtkWidget:has-tooltip property to %TRUE, this will make GTK+
52 * monitor the widget for motion and related events which are needed to
53 * determine when and where to show a tooltip.
58 * Connect to the #GtkWidget::query-tooltip signal. This signal will be
59 * emitted when a tooltip is supposed to be shown. One of the arguments passed
60 * to the signal handler is a GtkTooltip object. This is the object that we
61 * are about to display as a tooltip, and can be manipulated in your callback
62 * using functions like gtk_tooltip_set_icon(). There are functions for setting
63 * the tooltip's markup, setting an image from a stock icon, or even putting in
69 * Return %TRUE from your query-tooltip handler. This causes the tooltip to be
70 * show. If you return %FALSE, it will not be shown.
75 * In the probably rare case where you want to have even more control over the
76 * tooltip that is about to be shown, you can set your own #GtkWindow which
77 * will be used as tooltip window. This works as follows:
81 * Set #GtkWidget:has-tooltip and connect to #GtkWidget::query-tooltip as
87 * Use gtk_widget_set_tooltip_window() to set a #GtkWindow created by you as
93 * In the #GtkWidget::query-tooltip callback you can access your window using
94 * gtk_widget_get_tooltip_window() and manipulate as you wish. The semantics of
95 * the return value are exactly as before, return %TRUE to show the window,
96 * %FALSE to not show it.
