47 * @Short_description: A convenient message window
48 * @Title: GtkMessageDialog
49 * @See_also:#GtkDialog
51 * #GtkMessageDialog presents a dialog with an image representing the type of
52 * message (Error, Question, etc.) alongside some message text. It's simply a
53 * convenience widget; you could construct the equivalent of #GtkMessageDialog
54 * from #GtkDialog without too much effort, but #GtkMessageDialog saves typing.
56 * The easiest way to do a modal message dialog is to use gtk_dialog_run(), though
57 * you can also pass in the %GTK_DIALOG_MODAL flag, gtk_dialog_run() automatically
58 * makes the dialog modal and waits for the user to respond to it. gtk_dialog_run()
59 * returns when any dialog button is clicked.
61 * <title>A modal dialog.</title>
63 * dialog = gtk_message_dialog_new (main_application_window,
64 * GTK_DIALOG_DESTROY_WITH_PARENT,
67 * "Error loading file '%s': %s",
68 * filename, g_strerror (errno));
69 * gtk_dialog_run (GTK_DIALOG (dialog));
70 * gtk_widget_destroy (dialog);
73 * You might do a non-modal #GtkMessageDialog as follows:
75 * <title>A non-modal dialog.</title>
77 * dialog = gtk_message_dialog_new (main_application_window,
78 * GTK_DIALOG_DESTROY_WITH_PARENT,
81 * "Error loading file '%s': %s",
82 * filename, g_strerror (errno));
