本文介紹了帶有 Selenium 的應(yīng)用程序不響應(yīng) - 不顯示進度條，也不在控制臺中發(fā)出文本，直到任務(wù)完成的處理方法，對大家解決問題具有一定的參考價值，需要的朋友們下面隨著小編來一起學(xué)習(xí)吧！

問題描述

使用 PyQt5 和 selenium 時，窗口標題顯示為 Not Responding.腳本執(zhí)行完成后會顯示進度條和控制臺發(fā)射流.需要幫助來解決這個問題.

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.

   sys.exit(app.exec_())

我的實際結(jié)果應(yīng)該是當(dāng)我點擊應(yīng)用程序上的提交按鈕時，程序應(yīng)該開始執(zhí)行腳本，并且代碼中給出的 self.textEdit.insertPlainText 應(yīng)該隨著進度條的移動在文本編輯中流式傳輸.

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.

推薦答案

首先你有以下不良編程習(xí)慣:

Before all you have the following bad programming practices:

您正在用 GUI 搞亂業(yè)務(wù)邏輯.
變量名稱并未描述變量的用途.
一個文件中有很多代碼.

另一方面，轉(zhuǎn)到 Qt 你有以下錯誤:

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

您不應(yīng)從另一個線程修改 GUI，因為 GUI 不是安全的，您必須使用信號、事件等.
當(dāng)您更改大小時，您必須使用 GUI 布局來適應(yīng).

另一方面，我沒有測試你的代碼，但我發(fā)現(xiàn)你的一個錯誤是

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())

因為你是在調(diào)用函數(shù)而不是把它傳遞給函數(shù)，所以它必須是

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

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

考慮到上述情況，我實現(xiàn)了以下內(nèi)容:

Considering the above, I have implemented the following:
