如何从 QtDesigner 文件生成 python 代码？我找到了 pyside-uic 但我找不到语法示例。我用 spyder 运行 win7 和 pythonxy。

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)

我通常这样使用它：

pyside-uic -o output.py input.ui

刚刚尝试了 Pyside 的 QUILoader，工作正常：

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_()

我使用 Eclipse 和 QTDesigner 创建了 .ui 文件（右键单击模块，“New -> Other..”，选择“Qt Designer -> Qt Designer Form”）。不需要显式的 uic 调用。

pyside-uic.exe MyWindow.ui -o MyWindow.py

是我一直在做的，它工作正常（据我所知）

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

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...但是如果您不想转换，否则是的，以下是正确的方法。

pyside-uic.exe MyWindow.ui -o MyWindow.py

QUiLoader 类将在不制作中间文件的情况下完成这项工作。

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.

PySide 团队目前不鼓励使用 QtUiTools（如另一个答案中所建议的）。

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

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!

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.

pyside-uic MyWindow.ui -o MyWindow.py
