Python的GUI框架PySide的安装配置教程

(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

 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)

代码如下:

['__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:
