男 | 程序猿一只，喜欢编程写python代码。

我已经构建了一个运行几千行代码的应用程序。在

我试图通过将python代码编译成c代码，然后再编译到一个目标文件来隐藏代码。在

这个应用程序在pyside中运行良好。我将这个python文件py转换为.c文件，并编译了c-to和目标文件.o。此文件的名称为test2.py，我将其转换为.o文件的步骤：

 cython --embed -o test2.c test2.py

根据上面的内容，我现在将test2.c编译为test2.o，如下所示

^{pr2}$

我的问题是，在webkit框架中设计的minimize and close按钮在编译后不起作用（但是从python文件执行时效果很好），其他addtojavascripwindowbject也不工作

我用Pyside开发了一个简单的框架窗口模型，里面什么也没有

test2.py文件代码如下：我的密码在下面

from __future__ import print_function
import sys
import json
import threading
from time import sleep
from PySide.QtCore import *
from PySide.QtGui import *
from PySide.QtWebKit import QWebView, QWebSettings
from PySide.QtNetwork import QNetworkRequest

注意：我如何实现标题栏

我在名为^{的类中创建了一个webview框架

self.html_title_bar_webview=web_view_with_move(self)

我执行了一个init_signal（）类，它添加了javascript窗口对象

self.html_title_bar_webview.init_signals()

在
