1.需求

公司有一套系统，其中license数量(加密存储)有几项值是客户购买才能获得的，正常流程为客户购买，运维部准备一个UKEY，由系统灌注license相关数据送到客户现场，客户将UKEY插入服务器进行授权。

现需要开发一个小工具，供测试使用，测试输入liciense几项数据，生成对应密文数据。以下为另一个产品小工具截图

2.实现

上述图片为python开发，由于本人不会python，也不想做成黑色命令框那种。于是找了下go的gui库，发现fyne.io/fyne/v2使用率较高，简单看了下介绍感觉不错，便决定使用该库。

2.1解决中文乱码问题

func init() {
    //设置中文字体:解决中文乱码问题
    _ = sm4.SetIV(ivCbc)

    fontPaths := findfont.List()
    for _, path := range fontPaths {
       if strings.Contains(path, "msyh.ttf") || strings.Contains(path, "simhei.ttf") || strings.Contains(path, "simsun.ttc") || strings.Contains(path, "simkai.ttf") {
          os.Setenv("FYNE_FONT", path)
          break
       }
    }
}

2.2 数字和文本框一行显示

重点为layout.NewFormLayout()

pcEntry := widget.NewEntry()
pcEntry.SetPlaceHolder("输入pc端license数量")
pcLabel := widget.NewLabel("    PC端数量:")
pcContainer := fyne.NewContainerWithLayout(layout.NewFormLayout(), pcLabel, pcEntry)

2.3 按钮居中

fyne.NewContainerWithLayout(layout.NewCenterLayout(), myButton)

2.4设置布局大小

fyne.NewContainerWithLayout(layout.NewGridWrapLayout(fyne.NewSize(500, 110)), resEntry)
