InfoBar

GtkInfoBar can be 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 [class@Gtk.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 [method@Gtk.InfoBar.add_button] or [ctor@Gtk.InfoBar.new_with_buttons]. The sensitivity of action widgets can be controlled with [method@Gtk.InfoBar.set_response_sensitive].

To add widgets to the main content area of a GtkInfoBar, use [method@Gtk.InfoBar.add_child].

Similar to [class@Gtk.MessageDialog], the contents of a GtkInfoBar can by classified as error message, warning, informational message, etc, by using [method@Gtk.InfoBar.set_message_type]. 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

The GtkInfoBar implementation of the GtkBuildable interface exposes the content area and action area as internal children with the names “content_area” and “action_area”.

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 @action_area).

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.
