39  * `GtkInfoBar` can be show messages to the user without a dialog.
40  * 
41  * ![An example GtkInfoBar](info-bar.png)
42  * 
43  * It is often temporarily shown at the top or bottom of a document.
44  * In contrast to [class@Gtk.Dialog], which has an action area at the
45  * bottom, `GtkInfoBar` has an action area at the side.
46  * 
47  * The API of `GtkInfoBar` is very similar to `GtkDialog`, allowing you
48  * to add buttons to the action area with [method@Gtk.InfoBar.add_button]
49  * or [ctor@Gtk.InfoBar.new_with_buttons]. The sensitivity of action widgets
50  * can be controlled with [method@Gtk.InfoBar.set_response_sensitive].
51  * 
52  * To add widgets to the main content area of a `GtkInfoBar`, use
53  * [method@Gtk.InfoBar.add_child].
54  * 
55  * Similar to [class@Gtk.MessageDialog], the contents of a `GtkInfoBar`
56  * can by classified as error message, warning, informational message, etc,
57  * by using [method@Gtk.InfoBar.set_message_type]. GTK may use the message
58  * type to determine how the message is displayed.
59  * 
60  * A simple example for using a `GtkInfoBar`:
61  * ```c
62  * GtkWidget *message_label;
63  * GtkWidget *widget;
64  * GtkWidget *grid;
65  * GtkInfoBar *bar;
66  * 
67  * // set up info bar
68  * widget = gtk_info_bar_new ();
69  * bar = GTK_INFO_BAR (widget);
70  * grid = gtk_grid_new ();
71  * 
72  * message_label = gtk_label_new ("");
73  * gtk_info_bar_add_child (bar, message_label);
74  * gtk_info_bar_add_button (bar,
75  * _("_OK"),
76  * GTK_RESPONSE_OK);
77  * g_signal_connect (bar,
78  * "response",
79  * G_CALLBACK (gtk_widget_hide),
80  * NULL);
81  * gtk_grid_attach (GTK_GRID (grid),
82  * widget,
83  * 0, 2, 1, 1);
84  * 
85  * // ...
86  * 
87  * // show an error message
88  * gtk_label_set_text (GTK_LABEL (message_label), "An error occurred!");
89  * gtk_info_bar_set_message_type (bar, GTK_MESSAGE_ERROR);
90  * gtk_widget_show (bar);
91  * ```
92  * 
93  * # GtkInfoBar as GtkBuildable
94  * 
95  * The `GtkInfoBar` implementation of the `GtkBuildable` interface exposes
96  * the content area and action area as internal children with the names
97  * “content_area” and “action_area”.
98  * 
99  * `GtkInfoBar` supports a custom <action-widgets> element, which can contain
100  * multiple <action-widget> elements. The “response” attribute specifies a
101  * numeric response, and the content of the element is the id of widget
102  * (which should be a child of the dialogs @action_area).
103  * 
104  * # CSS nodes
105  * 
106  * `GtkInfoBar` has a single CSS node with name infobar. The node may get
107  * one of the style classes .info, .warning, .error or .question, depending
108  * on the message type.
109  * If the info bar shows a close button, that button will have the .close
110  * style class applied.
