Can not println when I run the systray on windows

func onReady() {
    systray.SetIcon(icon.Data)
    systray.SetTitle("端口转发服务")
    systray.SetTooltip("服务已最小化右下角, 右键点击打开菜单！")
    mShow := systray.AddMenuItem("显示", "显示窗口")
    mHide := systray.AddMenuItem("隐藏", "隐藏窗口")
    systray.AddSeparator()
    mQuit := systray.AddMenuItem("退出", "退出程序")

    consoleHandle, r2, err := getConsoleWindows.Call()
    if consoleHandle == 0 {

    }
    // hide
    mHide.Disable()
    mShow.Enable()

    if r1 != 1 {

    }

    go func() {
        for {
            select {
            case <-mShow.ClickedCh:
                mShow.Disable()
                mHide.Enable()
                r1, r2, err := showWindowAsync.Call(consoleHandle, 5)

            case <-mQuit.ClickedCh:
                systray.Quit()
                os.Exit(0)
            }
        }
    }()

}

When I run systray.Run(onReady, onExit) , the app can't println in the console. Can anybody tell me which options I set?
