Python 3 PyQT（使用设计器），开始出现问题
[英]Python 3 PyQT (Using Designer), having issues starting
问题描述
I am trying to branch out into developing a program with a GUI, and since I like KDE a lot I figured I would give PyQT a shot. 
我正在尝试扩展到使用GUI开发程序，并且由于我非常喜欢KDE，所以我认为我可以尝试一下PyQT。 Here's an example of what I have so far (no logic just yet, I wanted to see if I could get the UI to display). 这是到目前为止我所拥有的示例（目前还没有逻辑，我想看看是否可以显示UI）。
Here is the UI file named at.ui 这是名为at.ui的UI文件

The Python script to start it is: 启动它的Python脚本是：
#!/usr/bin/python3
from PyQt4 import QtGui, QtCore
import at_auto, os
class at(at_auto):
def __init__(self):
at_auto.__init__(self)
if __name__ == '__main__':
import sys
a = QtGui.QApplication(sys.argv)
QtCore.QObject.connect(a, QtCore.SIGNAL('lastWindowClosed()'), a, QtCore.SLOT('quit()'))
w = at(at_auto.__init__(self))
a.setMainWindow(w)
w.show()
a.exec_loop()
When attempting to run the program, I get the following error: 尝试运行程序时，出现以下错误：
Traceback (most recent call last):
File "./at.py", line 6, in <module>
class at(at_auto):
TypeError: module.__init__() takes at most 2 arguments (3 given)
I modified the code in at.py from the following tutorial: 我从以下教程中修改了at.py中的代码：

Thank you so much! 非常感谢！

Firstly: that tutorial you linked to is very out of date (it relates to PyQt3 rather than PyQt4), so I would suggest you have a look here for something more recent. 首先：您链接到的教程已经过时了（它与PyQt3而不是PyQt4有关），所以我建议您在这里查找最新的内容。
But to deal with the issue at hand - it will simplify things somewhat if you start by recompiling the ui using this command: 但是要解决当前的问题-如果使用以下命令重新编译ui，它将使事情有所简化：
pyuic4 -w at.ui > at_auto.py
The -w option will generate an additional GUI class that is much more intuitive to use than the one created by default. -w选项将生成一个附加的GUI类，它比默认创建的GUI类使用起来更加直观。 The name of this class will have the same name as the top-level object created in Qt Designer - in your case, this will be MainWindow . 此类的名称与Qt Designer中创建的顶级对象的名称相同-在您的情况下，该名称为MainWindow 。
To use it, just import it into your main script, create a subclass, and then show an instance of it, like this: 要使用它，只需将其导入您的main脚本，创建一个子类，然后show它的实例，如下所示：
from PyQt4 import QtGui, QtCore
from at_auto import MainWindow
class Window(MainWindow):
def __init__(self):
MainWindow.__init__(self)
# do other initialization stuff here...
if __name__ == '__main__':
import sys
app = QtGui.QApplication(sys.argv)
window = Window()
window.show()
sys.exit(app.exec_())
