Python code generation with pyside-uic
提问by ArtDijk
How can I generate python code from a QtDesigner file ? I found pyside-uic but I can't find an example for the syntax. I run win7 and pythonxy with spyder.
如何从 QtDesigner 文件生成 python 代码？我找到了 pyside-uic，但找不到语法示例。我用 spyder 运行 win7 和 pythonxy。

Read the documentation. In this particular case, http://www.riverbankcomputing.co.uk/static/Docs/PyQt4/pyqt4ref.html#pyuic4:
阅读文档。在这种特殊情况下，http: //www.riverbankcomputing.co.uk/static/Docs/PyQt4/pyqt4ref.html#pyuic4：
The pyuic4 utility is a command line interface to the uic module. The command has the following syntax:
pyuic4 [options] .ui-file
The full set of command line options is:
-h, --help A help message is written to stdout.
--version The version number is written to stdout.
-i N, --indent=N
The Python code is generated using an indentation of N spaces. If N is 0 then a tab is used. The default is 4.
-o FILE, --output=FILE
The Python code generated is written to the file FILE.
-p, --preview The GUI is created dynamically and displayed. No Python code is generated.
-w, --pyqt3-wrapper
The generated Python code includes a small wrapper that allows the GUI to be used in the same way as it is used in PyQt v3.
-x, --execute The generated Python code includes a small amount of additional code that creates and displays the GUI when it is executes as a standalone application.
--from-imports Resource modules are imported using from . import rather than a simple import.

QUiLoader class will do the job without making an intermediate file.
QUiLoader 类将在不制作中间文件的情况下完成这项工作。

pyside-uic is more or less identical to pyuic4, as such the man page specifies:
pyside-uic 或多或少与 pyuic4 相同，因此手册页指定：
Usage:
pyside-uic [options] <ui-file>
Options:
--version
show program's version number and exit
-h,--help
show this help message and exit
-oFILE,--output=FILE
write generated code to FILE instead of stdout
-x,--execute
generate extra code to test and display the class
-d,--debug
show debug output
-iN,--ident=N
set indent width to N spaces, tab if N is 0 (default: 4)
I usually use it like this:
我通常这样使用它：
pyside-uic -o output.py input.ui

pyside-uic.exe MyWindow.ui -o MyWindow.py
is what I've been doing and it's working fine (as far as I know)
是我一直在做的，并且运行良好（据我所知）

Just tried Pyside's QUILoader, works fine:
刚试过 Pyside 的 QUILoader，效果很好：
from PySide import QtGui
from PySide import QtCore
from PySide import QtUiTools
class MyWidget(QtGui.QMainWindow):
def __init__(self, *args):
apply(QtGui.QMainWindow.__init__, (self,) + args)
loader = QtUiTools.QUiLoader()
file = QtCore.QFile("pyside_ui_qtdesigner_form_test.ui")
file.open(QtCore.QFile.ReadOnly)
self.myWidget = loader.load(file, self)
file.close()
self.setCentralWidget(self.myWidget)
if __name__ == '__main__':
import sys
import os
print("Running in " + os.getcwd() + " .\n")
app = QtGui.QApplication(sys.argv)
win = MyWidget()
win.show()
app.connect(app, QtCore.SIGNAL("lastWindowClosed()"),
app, QtCore.SLOT("quit()"))
app.exec_()
I used Eclipse and QTDesigner to create the .ui file (right-click on module, "New -> Other..", choose "Qt Designer -> Qt Designer Form"). No explicit uic call is needed.
我使用 Eclipse 和 QTDesigner 创建 .ui 文件（右键单击模块，“新建 -> 其他..”，选择“Qt 设计器 -> Qt 设计器表单”）。不需要显式的 uic 调用。

Using QtUiTools (as suggested in another answer) is currently discouraged by the PySide team.
PySide 团队目前不鼓励使用 QtUiTools（如另一个答案中所建议的）。

import pysideuic
import xml.etree.ElementTree as xml
from cStringIO import StringIO
def loadUiType(uiFile):
"""
Pyside "loadUiType" command like PyQt4 has one, so we have to convert the
ui file to py code in-memory first and then execute it in a special frame
to retrieve the form_class.
"""
parsed = xml.parse(uiFile)
widget_class = parsed.find('widget').get('class')
form_class = parsed.find('class').text
with open(uiFile, 'r') as f:
o = StringIO()
frame = {}
pysideuic.compileUi(f, o, indent=0)
pyc = compile(o.getvalue(), '<string>', 'exec')
exec pyc in frame
# Fetch the base_class and form class based on their type
# in the xml from designer
form_class = frame['Ui_%s'%form_class]
base_class = eval('QtGui.%s'%widget_class)
return form_class, base_class
You can use this way to load the UI and can also get form_class as well as the base class as return type... but if you do not want to convert, otherwise Yes the following is the correct way.
您可以使用这种方式加载 UI，也可以获取 form_class 以及基类作为返回类型...但如果您不想转换，否则是的，以下是正确的方法。
pyside-uic.exe MyWindow.ui -o MyWindow.py

Look at C:\Python27\Lib\site-packages\PySide\scripts\uic.py (or wherever you have python installed). If you look at that script you can see the options labelled and described as in the man page (Which I don't know how to view properly on windows. Tips appreciated.) here http://manpages.ubuntu.com/manpages/precise/man1/pyside-uic.1.html
查看 C:\Python27\Lib\site-packages\PySide\scripts\uic.py（或任何安装了 python 的地方）。如果您查看该脚本，您可以看到手册页中标记和描述的选项（我不知道如何在 Windows 上正确查看。感谢提示。）在这里http://manpages.ubuntu.com/manpages/精确/man1/pyside-uic.1.html
I got confused for a while trying to look at C:\Python27\Lib\site-packages\pysideuic\pyside-uic.1 as I thought that must be the file that is being called. Even trying to view that as a manual page is impossible for me because of all the extra characters. You can't learn syntax by trying to guess at which characters are extra and which ones aren't!
我在尝试查看 C:\Python27\Lib\site-packages\pysideuic\pyside-uic.1 时感到困惑，因为我认为这必须是正在调用的文件。由于所有额外的字符，即使尝试将其视为手册页对我来说也是不可能的。你不能通过猜测哪些字符是多余的，哪些不是的来学习语法！
On windows you can automate this with a batch file of course by saving a text file with the above mentioned line(below for reference) with .bat extension like uic_generator.bat.
在 Windows 上，您当然可以使用批处理文件自动执行此操作，方法是使用 uic_generator.bat 等 .bat 扩展名保存带有上述行（以下供参考）的文本文件。
pyside-uic MyWindow.ui -o MyWindow.py
pyside-uic MyWindow.ui -o MyWindow.py
