    if err != nil {
        log.Panicln(err)
    }
    defer g.Close()

    g.SetManagerFunc(layout)

    if err := g.SetKeybinding("", gocui.KeyCtrlC, gocui.ModNone, quit); err != nil {
        log.Panicln(err)

    if err := g.MainLoop(); err != nil && err != gocui.ErrQuit {
        log.Panicln(err)
    }
}

func layout(g *gocui.Gui) error {
    maxX, maxY := g.Size()
    if v, err := g.SetView("hello", maxX/2-7, maxY/2, maxX/2+7, maxY/2+2); err != nil {
        if err != gocui.ErrUnknownView {
            return err
        }
