Question

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

Answer 1

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)

我通常会这样使用它：

pyside-uic -o output.py input.ui

刚试过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.ui文件（右键单击模块，“New - ＆gt; Other ..”，选择“Qt Designer - ＆gt; Qt Designer Form”）。不需要明确的uic调用。

Answer 3

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，也可以将form_class和基类作为返回类型...但如果您不想转换，否则以下是正确的方法。

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

Answer 4

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

是我一直在做的事情，并且工作正常（据我所知）

Answer 5

QUiLoader类可以在不制作中间文件的情况下完成工作。

Answer 6

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（如另一个答案所示）。

查看C：\ Python27 \ Lib \ site-packages \ PySide \ scripts \ uic.py（或安装了python的地方）。如果您查看该脚本，您可以在手册页中看到标记和描述的选项（我不知道如何在Windows上正确查看。提示赞赏。）http://manpages.ubuntu.com/manpages/precise/man1/pyside-uic.1.html

我有点困惑，试图查看C：\ Python27 \ Lib \ site-packages \ pysideuic \ pyside-uic.1因为我认为必须是被调用的文件。由于所有额外的角色，我甚至试图将其视为手册页是不可能的。你不能通过猜测哪些字符是额外的而哪些不是哪些来学习语法！

在Windows上，您可以使用批处理文件自动执行此操作，方法是保存带有上述行的文本文件（如下所示），扩展名为.bat扩展名，如uic_generator.bat。

pyside-uic MyWindow.ui -o MyWindow.py

使用pyside-uic生成Python代码
