这篇文章主要为大家详细介绍了PySide和PyQt加载ui文件的两种方法，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

本文实例为大家分享了PySide和PyQt加载ui文件的具体实现代码，供大家参考，具体内容如下

在用PySide或PyQt的时候，经常用到要将画好的ui文件导入到代码里使用，下面是两种调入的方法：

				?

									import PyQt4.uic

									from PyQt4 import QtCore, QtGui

									MainWindowForm, MainWindowBase = PyQt4.uic.loadUiType('ui/mainwindow.ui')

									class MainWindow(MainWindowBase, MainWindowForm):

									 def __init__(self, parent = None):

									  super(MainWindow, self).__init__(parent)

									  # setup the ui

									  self.setupUi(self)

									if ( __name__ == '__main__' ):

									 app = None

									 if ( not app ):

									  app = QtGui.QApplication([])

									 window = MainWindow()

									 window.show()

									 if ( app ):

									  app.exec_()

第二种：

				?

									import PyQt4.uic

									from PyQt4 import QtCore, QtGui

									class MainWindow(QtGui.QMainWindow):

									 def __init__(self, parent = None):

									  super(MainWindow, self).__init__(parent)

									  # load the ui

									  PyQt4.uic.loadUi('ui/mainwindow.ui', self)

									if ( __name__ == '__main__' ):

									 app = None

									 if ( not app ):

									  app = QtGui.QApplication([])

									 window = MainWindow()

									 window.show()

									 if ( app ):

									  app.exec_()

当然如果是用PySide的话，我们可以写个专门读取ui文件的方法，将baseclass和formclass返回出去，供后面UI的类继承。

				?

									# -*- coding: utf-8 -*-

									from PySide import QtGui

									import xml.etree.ElementTree as xml

									from cStringIO import StringIO

									def load_ui_file(ui_file, type='PySide'):

									 if type == 'PySide':

									  import pysideuic

									  print pysideuic

									  parsed = xml.parse(ui_file)

									  widget_class = parsed.find('widget').get('class')

									  form_class = parsed.find('class').text

									  with open(ui_file, 'r') as f:

									   o = StringIO()

									   frame = {}

									   pysideuic.compileUi(f, o, indent=0)

									   pyc = compile(o.getvalue(), '<string>', 'exec')

									   exec pyc in frame

									   form_class = frame['Ui_%s' % form_class]

									   base_class = getattr(QtGui, widget_class)

									  return form_class, base_class

									 elif type == 'PyQt4':

									  import PyQt4.uic

									  return PyQt4.uic.loadUiType(ui_file)

									if __name__ == "__main__":

									 ui_file = 'test.ui'

									 load_ui_file(ui_file)
