/ 10 февраля 2012

Я пытаюсь перейти к разработке программы с графическим интерфейсом, и, поскольку мне очень нравится KDE, я решил, что я бы попробовал PyQT. Вот пример того, что у меня есть (пока нет логики, я хотел посмотреть, смогу ли я отобразить интерфейс).

Вот файл пользовательского интерфейса с именем at.ui

Скрипт Python для запуска: 

#!/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()

При попытке запустить программу я получаю следующую ошибку: 

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)

Я изменил код в at.py из следующего урока:

http://wiki.python.org/moin/JonathanGardnerPyQtTutorial#Using_pyuic

Спасибо большое!

Во-первых: этот учебник, на который вы ссылаетесь, очень устарел (он относится к PyQt3, а не к PyQt4), поэтому я бы посоветовал вам посмотреть здесь на что-то более новое.

Но для решения данной проблемы - это несколько упростит ситуацию, если вы начнете с перекомпиляции пользовательского интерфейса с помощью этой команды: 

pyuic4 -w at.ui > at_auto.py

Опция -w создаст дополнительный класс графического интерфейса, который гораздо болееИнтуитивно понятен в использовании, чем тот, который создан по умолчанию.Имя этого класса будет иметь то же имя, что и объект верхнего уровня, созданный в Qt Designer - в вашем случае это будет MainWindow.

Чтобы использовать его, просто импортируйте его в mainсценарий, создайте подкласс, а затем show его экземпляр, например: 

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_())
...
