带有 Selenium 的应用程序不响应 - 不显示进度条，也不在控制台中发出文本，直到任务完成 [英] App with Selenium Not Responding - Not showing the progress bar and Not Emitting the text in Console until the task is completed

问题描述

使用 PyQt5 和 selenium 时，窗口标题显示为 Not Responding.脚本执行完成后会显示进度条和控制台发射流.需要帮助来解决这个问题.

Window title is showing as Not Responding when using PyQt5 and selenium. The progress bar and the console emit stream displays after the completion of execution of script. Need help in getting this fixed.

   Fuse = QtWidgets.QDialog()
   ui = Ui_Fuse()
   ui.setupUi(Fuse)
   Fuse.show()
   sys.exit(app.exec_())

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 应该随着进度条的移动在文本编辑中流式传输.

My actual result should be when i hit the submit button on the app, the program should start executing the script and the self.textEdit.insertPlainText given in the code should stream in the text edit with progress bar moving.

推荐答案

首先你有以下不良编程习惯:

Before all you have the following bad programming practices:

• 您正在用 GUI 搞乱业务逻辑.
• 变量名称并未描述变量的用途.
• 一个文件中有很多代码.

另一方面，转到 Qt 你有以下错误:

On the other hand going to Qt you have the following errors:

• 您不应从另一个线程修改 GUI，因为 GUI 不是安全的，您必须使用信号、事件等.
• 当您更改大小时，您必须使用 GUI 布局来适应.

另一方面，我没有测试你的代码，但我发现你的一个错误是

On the other hand I have not tested your code but I see that one of your errors is

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

因为你是在调用函数而不是把它传递给函数，所以它必须是

since you are invoking the function instead of passing it to the function, it must be

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

考虑到上述情况，我实现了以下内容:

Considering the above, I have implemented the following:
