我正在使用PyQt编写Qt5应用程序.我想了解如何更改整个应用程序的样式.

旧的Qt4称之为

app = QApplication(sys.argv)
app.setStyle(QStyleFactory.create('Cleanlooks'))

这里建议什么都不做.

他们被弃用了吗？ https://blog.qt.io/blog/2012/10/30/cleaning-up-styles-in-qt5-and-adding-fusion/

谢谢!

最近，我在系统上安装了PyQt4，并开始执行一些基本任务（课程工作），效果很好。

然后，几天后，我尝试与一起工作matplotlib。

当我尝试时import matplotlib.pyplot as plt，出现以下错误：

Traceback (most recent call last):

    import matplotlib.pyplot as plt

我正在运行Ubuntu 13.10(python-3.3.2 +).我从官方网站的源代码安装了Qt5.2.1(linux安装程序),SIP 4.15.5和PyQt5.
