There is no replacement in GTK for an "info bar" widget; you can use Revealer with a Box containing a Label and an optional Button, according to your application's design.
GtkInfoBar can be used to show messages to the user without a dialog.

An example GtkInfoBar

It is often temporarily shown at the top or bottom of a document. In contrast to Dialog, which has an action area at the bottom, GtkInfoBar has an action area at the side.

The API of GtkInfoBar is very similar to GtkDialog, allowing you to add buttons to the action area with addButton(java.lang.String, int) or withButtons(java.lang.String, java.lang.Object...). The sensitivity of action widgets can be controlled with setResponseSensitive(int, boolean).

To add widgets to the main content area of a GtkInfoBar, use addChild(org.gnome.gtk.Widget).

Similar to MessageDialog, the contents of a GtkInfoBar can by classified as error message, warning, informational message, etc, by using setMessageType(org.gnome.gtk.MessageType). GTK may use the message type to determine how the message is displayed.

A simple example for using a GtkInfoBar: 

GtkWidget *message_label;
 GtkWidget *widget;
 GtkWidget *grid;
 GtkInfoBar *bar;

 // set up info bar
 widget = gtk_info_bar_new ();
 bar = GTK_INFO_BAR (widget);
 grid = gtk_grid_new ();

 message_label = gtk_label_new ("");
 gtk_info_bar_add_child (bar, message_label);
 gtk_info_bar_add_button (bar,
                          _("_OK"),
                          GTK_RESPONSE_OK);
 g_signal_connect (bar,
                   "response",
                   G_CALLBACK (gtk_widget_hide),
                   NULL);
 gtk_grid_attach (GTK_GRID (grid),
                  widget,
                  0, 2, 1, 1);

 // ...

 // show an error message
 gtk_label_set_text (GTK_LABEL (message_label), "An error occurred!");
 gtk_info_bar_set_message_type (bar, GTK_MESSAGE_ERROR);
 gtk_widget_show (bar);

GtkInfoBar as GtkBuildable
GtkInfoBar supports a custom <action-widgets> element, which can contain multiple <action-widget> elements. The “response” attribute specifies a numeric response, and the content of the element is the id of widget (which should be a child of the dialogs actionArea).

GtkInfoBar supports adding action widgets by specifying “action” as the “type” attribute of a <child> element. The widget will be added either to the action area. The response id has to be associated with the action widget using the <action-widgets> element.

CSS nodes
GtkInfoBar has a single CSS node with name infobar. The node may get one of the style classes .info, .warning, .error or .question, depending on the message type. If the info bar shows a close button, that button will have the .close style class applied.
