47/**
48 * SECTION:ctktooltip
49 * @Short_description: Add tips to your widgets
50 * @Title: CtkTooltip
51 *
52 * Basic tooltips can be realized simply by using ctk_widget_set_tooltip_text()
53 * or ctk_widget_set_tooltip_markup() without any explicit tooltip object.
54 *
55 * When you need a tooltip with a little more fancy contents, like adding an
56 * image, or you want the tooltip to have different contents per #CtkTreeView
57 * row or cell, you will have to do a little more work:
58 *
59 * - Set the #CtkWidget:has-tooltip property to %TRUE, this will make CTK+
60 * monitor the widget for motion and related events which are needed to
61 * determine when and where to show a tooltip.
62 *
63 * - Connect to the #CtkWidget::query-tooltip signal. This signal will be
64 * emitted when a tooltip is supposed to be shown. One of the arguments passed
65 * to the signal handler is a CtkTooltip object. This is the object that we
66 * are about to display as a tooltip, and can be manipulated in your callback
67 * using functions like ctk_tooltip_set_icon(). There are functions for setting
68 * the tooltip’s markup, setting an image from a named icon, or even putting in
69 * a custom widget.
70 *
71 * Return %TRUE from your query-tooltip handler. This causes the tooltip to be
72 * show. If you return %FALSE, it will not be shown.
73 *
74 * In the probably rare case where you want to have even more control over the
75 * tooltip that is about to be shown, you can set your own #CtkWindow which
76 * will be used as tooltip window. This works as follows:
77 *
78 * - Set #CtkWidget:has-tooltip and connect to #CtkWidget::query-tooltip as before.
79 * Use ctk_widget_set_tooltip_window() to set a #CtkWindow created by you as
80 * tooltip window.
81 *
82 * - In the #CtkWidget::query-tooltip callback you can access your window using
83 * ctk_widget_get_tooltip_window() and manipulate as you wish. The semantics of
84 * the return value are exactly as before, return %TRUE to show the window,
85 * %FALSE to not show it.
