Spinners¶

Spinner 是一个占位符，用于后台执行的长时间运行的操作。

界面指南

static gboolean
stop_spinner (gpointer data)
{
  GtkSpinner *spinner = data;

  gtk_spinner_stop (spinner);

  return G_SOURCE_REMOVE;
}

GtkWidget *spinner = gtk_spinner_new ();

gtk_spinner_start (GTK_SPINNER (spinner));

// Stop spinner after 5 seconds
g_timeout_add_seconds (5, stop_spinner, spinner);

spinner = Gtk.Spinner()
spinner.start()

def stop_spinner(spinner):
    spinner.stop()
    return GLib.SOURCE_REMOVE

GLib.timeout_add_seconds(5, stop_spinner, spinner)

var spinner = new Gtk.Spinner ();
spinner.start ();

// Stop spinner after 5 seconds
Timeout.add_seconds (5, () => {
    spinner.stop ();
    return Source.REMOVE;
});

const spinner = new Gtk.Spinner();
spinner.start();

// Stop spinner after 5 seconds
GLib.timeout_add_seconds(GLib.PRIORITY_DEFAULT, 5, () => {
  spinner.stop();
  return GLib.SOURCE_REMOVE;
});
