QtiPlot和Python:未定义全局名称“QLocale”

Question

我正在开发一个将在名为QtiPlot的应用程序中运行的Python。我为Python搜索了Qtiplot的文档，它使用了PyQt 4。

#! /usr/bin/env python

# A python script to be used in QtiPlot to convert .dat files into .jpg graphs and these ones into .avi movie

import os
import re
import glob
from PyQt4 import uic
from PyQt4 import *

def chooseInputFolder():
    input_folder = QtGui.QFileDialog.getExistingDirectory(qti.app, "Choose Working Folder")
    ui.inputFolderLine.setText(input_folder)
    return input_folder

def chooseOutputFile():
    output_file = QtGui.QFileDialog.getSaveFileName(qti.app, "Choose Output File")
    ui.outputFileLine.setText(output_file)
    return output_file

def createVideoFromJPG():
    input_folder_name = ui.inputFolderLine.text()
    output_file_name = ui.outputFileLine.text()
    dirList = os.listdir(input_folder_name)
    for fname in dirList:
        t = newTable()
        t.importASCII(input_folder_name+fname,sep="\t",ignoreLines=0,renameCols=False,stripSpaces=True,simplifySpace=False,importComments=False,comment="#",readOnly=False,importAs=Table.Overwrite,locale=QLocale(),endLine=0,maxRows=-1)
#       g = plot(t, 2, 0)
#       cmd = 'mencoder "mf://*.jpg" -mf fps=25 -o %s -ovc lavc -lavcopts vcodec=mpeg4' % output_file
#       os.system(cmd)

ui = uic.loadUi("/home/kurumin/Scripts/python/dat2vid.ui")
ui.connect(ui.inputFolderButton, QtCore.SIGNAL("clicked()"),chooseInputFolder)
ui.connect(ui.outputFileButton, QtCore.SIGNAL("clicked()"),chooseOutputFile)
ui.connect(ui.createVideo, QtCore.SIGNAL("clicked()"),createVideoFromJPG)
ui.show()

这是输出：

Traceback (most recent call last):

File "<>", line 27, in createVideoFromJPG

NameError
: 
global name 'QLocale' is not defined

我试图定义QLocale，但在文档中找不到真正有用的东西。

Answer 1

在文件的locale=QLocale()第27行()中替换locale=QtGui.QLocale()的，因为from PyQt4 import *必须提供模块名。
