python - Selenium 的应用程序没有响应 - 不显示进度条，并且在任务完成之前不在控制台中发出文本

转载作者：行者123 更新时间：2023-12-01 01:06:23

使用 PyQt5 和 selenium 时，窗口标题显示为“无响应”。脚本执行完成后将显示进度条和控制台发出流。需要帮助来解决这个问题。

我的实际结果应该是当我点击应用程序上的提交按钮时，程序应该开始执行脚本，并且代码中给出的 self.textEdit.insertPlainText 应该在文本编辑中流动，进度条移动。

最佳答案

首先，您有以下不良编程习惯:

您用 GUI 搞乱了业务逻辑。
变量的名称并不描述变量的用途。
一个文件中有很多代码。

另一方面，转到 Qt 时，您会遇到以下错误:

您不应该从另一个线程修改 GUI，因为 GUI 不是线程安全的，您必须使用信号、事件等。
您必须使用 GUI 布局，以便在更改大小时进行调整。

另一方面，我没有测试您的代码，但我发现您的错误之一是

t = threading.Thread(target=self.generate())

由于您是调用函数而不是将其传递给函数，因此它必须是

t = threading.Thread(target=self.generate)

考虑到上述情况，我实现了以下内容:
