QtDesigner PyQt4 Python

本文讲述用QtDesigner创建GUI，通过PyQt4转化为可执行的Python文件

1. QtDesigner创建一个GUI后会生成一个 .ui文件（eg： TestUI.ui）

2. 通过命令 Python pyuic.py -o TestUI.py TestUI.ui 生成我们需要的py文件（TestUI.py）

3. 创建一个 Test.py 文件，编辑以下代码：

 1 import sys
 2 from PyQt4.QtGui import *  
 3 from PyQt4.QtCore import *
 4 import TestUI
 5       
 6 class uitest( QMainWindow,TestUI.Ui_MainWindow):     
 7     def __init__(self, parent=None):  
 8         super(uitest, self).__init__(parent)   
 9         self.setupUi(self)  
10       
11 app = QApplication(sys.argv)  
12 w = uitest()  
13 w.show()
14 app.exec_()

4. Python Test.py 即可得到步骤1中设计的GUI

注：pyuic参数说明：

NAME
pyuic4 - compile Qt4 user interfaces to Python code
SYNOPSIS
pyuic4 [OPTION]... FILE
DESCRIPTION
pyuic4 takes a Qt4 user interface description file and compiles it to
Python code. It can also show a preview of the user interface.
OPTIONS
-h, --help
Show a summary of the options.
--version
Display the version number of pyuic4 of the version of Qt which
PyQt4 was generated for.
-p, --preview
Show a preview of the UI instead of generating Python code.
-o, --output=FILE
Write the generated Python code to FILE instead of stdout.
-d, --debug
Show detailed debugging information about the UI generation
process.
-x, --execute
Generate extra code to test and display the class when executed
as a script.
-i, --indent=NUM
Set the indentation width to NUM spaces. A TAB character will be
used if NUM is 0 (default: 4).
