（一）说在前面
Python自带了GUI模块Tkinter，只是界面风格有些老旧。另外就是各种GUI框架了。
之前安装过WxPython，并做了简单的界面。遂最近又重新搜索了一下网上关于Python GUI框架的问题，发现还是Qt呀。
Python的Qt有PyQt和PySide吧。PyQt 是商业及 GPL 的版权， 而 PySide 是 LGPL。大意也就是PyQt开发商业软件是要购买授权的，而PySide则不需要。二者代码基本一致，修改下import 基本剩余的代码皆可通用。所以毫不犹豫的选择了PySide。
（二）PySide的安装
（1）比较快捷省事的安装
dizzy@dizzy-pc:~$ sudo add-apt-repository ppa:pyside
You are about to add the following PPA to your system: Official Ubuntu packages for PySide Qt Bindings.
dizzy@dizzy-pc:~$ sudo apt-get update
# ... ... dizzy@dizzy-pc:~$ sudo apt-get install python-pyside Reading package lists... Done Building dependency tree Reading state information... Done The following extra packages will be installed: libphonon4 libpyside1.1 libqt4-help libqt4-scripttools libqt4-test libqtwebkit4 libshiboken1.1 phonon phonon-backend-gstreamer python-pyside.phonon python-pyside.qtcore python-pyside.qtdeclarative python-pyside.qtgui python-pyside.qthelp python-pyside.qtnetwork python-pyside.qtopengl python-pyside.qtscript python-pyside.qtsql python-pyside.qtsvg python-pyside.qttest python-pyside.qtuitools python-pyside.qtwebkit python-pyside.qtxml
（2）测试是否安装成功
dizzy@dizzy-pc:~$ python
Python 2.7.3 (default, Feb 27 2014, 20:00:17) [GCC 4.6.3] on linux2 Type "help", "copyright", "credits" or "license" for more information.
>>> import PySide >>> dir(PySide)
['__all__', '__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__', '__version__', '__version_info__']
>>> PySide.__version__
'1.1.2'
>>> PySide.QtCore.__version__
'4.8.1'
（三）PySide初试
# -*- coding: utf-8 -*-
# Import PySide classes
import sys
from PySide.QtCore import *
from PySide.QtGui import *
# Create a Qt application
app = QApplication(sys.argv)
# Create a Label and show it
label = QLabel("Hello World")
label.show()
# Enter Qt application main loop
app.exec_()
sys.exit()
这样运行就可以看到一个最简单的窗口了。Hello World .
（四）Hello，PySide
第一个使用PySide的示例，新建一个Hello.py文件，输入以下内容：
# Import PySide classes
import sys
from PySide.QtCore import *
from PySide.QtGui import *
# Create a Qt application
app = QApplication(sys.argv)
# Create a Label and show it
label = QLabel("Hello World")
label.show()
# Enter Qt application main loop
app.exec_()
sys.exit()
双击该文件，运行结果：
