+/**
+ * SECTION:gtkmessagedialog
+ * @Short_description: A convenient message window
+ * @Title: GtkMessageDialog
+ * @See_also:#GtkDialog
+ *
+ * #GtkMessageDialog presents a dialog with an image representing the type of
+ * message (Error, Question, etc.) alongside some message text. It's simply a
+ * convenience widget; you could construct the equivalent of #GtkMessageDialog
+ * from #GtkDialog without too much effort, but #GtkMessageDialog saves typing.
+ *
+ * One difference from #GtkDialog is that #GtkMessageDialog sets the
+ * #GtkWindow:skip-taskbar-hint property to %TRUE, so that the dialog is hidden
+ * from the taskbar by default.
+ *
+ * The easiest way to do a modal message dialog is to use gtk_dialog_run(), though
+ * you can also pass in the %GTK_DIALOG_MODAL flag, gtk_dialog_run() automatically
+ * makes the dialog modal and waits for the user to respond to it. gtk_dialog_run()
+ * returns when any dialog button is clicked.
+ * <example>
+ * <title>A modal dialog.</title>
+ * <programlisting>
+ * dialog = gtk_message_dialog_new (main_application_window,
+ * GTK_DIALOG_DESTROY_WITH_PARENT,
+ * GTK_MESSAGE_ERROR,
+ * GTK_BUTTONS_CLOSE,
+ * "Error loading file '%s': %s",
+ * filename, g_strerror (errno));
+ * gtk_dialog_run (GTK_DIALOG (dialog));
+ * gtk_widget_destroy (dialog);
+ * </programlisting>
+ * </example>
+ * You might do a non-modal #GtkMessageDialog as follows:
+ * <example>
+ * <title>A non-modal dialog.</title>
+ * <programlisting>
+ * dialog = gtk_message_dialog_new (main_application_window,
+ * GTK_DIALOG_DESTROY_WITH_PARENT,
+ * GTK_MESSAGE_ERROR,
+ * GTK_BUTTONS_CLOSE,
+ * "Error loading file '%s': %s",
+ * filename, g_strerror (errno));
+ *
+ * /* Destroy the dialog when the user responds to it (e.g. clicks a button) */
+ * g_signal_connect_swapped (dialog, "response",
+ * G_CALLBACK (gtk_widget_destroy),
+ * dialog);
+ * </programlisting>
+ * </example>
+ *
+ * <refsect2 id="GtkMessageDialog-BUILDER-UI">
+ * <title>GtkMessageDialog as GtkBuildable</title>
+ * <para>
+ * The GtkMessageDialog implementation of the GtkBuildable interface exposes
+ * the message area as an internal child with the name "message_area".
+ * </para>
