Python code generation with pyside-uic

Question

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.

Answer 1

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(), '', '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.

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