【问题描述】：
我有一个关于代码结构的可能非常简单的问题
我编写了一个连接到 Web 套接字以检索数据然后进行大量计算的应用程序
基本上，websocket 在一个线程中打开，主循环中的繁重计算随后是控制台显示。需要注意的是，我可能不得不使用多处理将代码拆分到多个内核上。
我现在正在尝试在 wxpython 中显示。我制作了一个带有 GUI 的单独项目，它本身可以正常工作。主循环是：
def main():
app = wx.App()
ex = MainWindows(rows)
app.MainLoop()
if __name__ == '__main__':
main()
MainWindows 函数就是这样开始的：
class MainWindows(wx.Frame):
def __init__(self, *args, **kwargs):
super(MainWindows, self).__init__(data=rows, *args, **kwargs)
self.InitUI(rows)
def InitUI(self, rows):
# Set Frame options
self.SetSize((800, 600))
self.SetTitle('Title')
self.Centre()
...
现在想知道如何完成后台繁重的计算以及如何将参数传递给我的 MainWindows 类。 我试过调查 *args 和 **kwargs 但没有成功。总是编译错误说我的班级不参加更多参数。
所以我的问题是：
-
集成后台计算、websocket 处理等的最佳方式是什么（我认为放入线程是最好的）
-
如何与我的 GUI 共享数据（参数传递）
-
如何定期（例如每秒）刷新小部件以使用在单独线程中处理的 websocket 中的日期进行更新（实际上我正在尝试在 ListCtrl 小部件中显示我的 websocked 处理的内容并希望在实时
我想在其中显示我的数据的完整测试 GUI 代码（请参阅订单选项卡）。变量 rows 是来自 websocket 数据的后台计算的数据示例：
Version_Major = 3
Version_Minor = 0
Version_patch = 0
