I am trying to build a GUI for navigating through a large XML
database on a Mac running OS 10.7, Python 3.3, PyQt 4. I want to get
a list of the text in all of the nodes calledOrth and put them into
a QListWidget called hLexNav. To do this, I wrote the following bit
of code (this isn't the whole thing, just the parts that are supposed
to add items to the listbox):
import sys
from PyQt4 import QtCore, QtGui
from xml.dom import minidom
import xml.etree.ElementTree as etree
from fieldbookGui import Ui_Fieldbook
import images
import btnCmds
class MyForm(QtGui.QMainWindow):
def __init__(self, parent=None):
QtGui.QWidget.__init__(self, parent)
self.ui = Ui_Fieldbook()
self.ui.setupUi(self)
xmltree = etree.parse('BabyDb.xml')
root = xmltree.getroot()
for child in root:
self.ui.hLexNav.addItem(child.findtext('Orth'))
The first 25 items that are returned by child.findtext('Orth') are:
['a:', 'a:ch?j', 'a:chul?:', a:h?:xtu', 'a:ho:t?n', 'a:k?s',
a:li:ma'ht?n, 'a:li:st?:n', 'a:m?', a:ma'ha:'pi'tz?'n,
'a:mixtzay?n', 'a:nan?:', 'a:t?:n', 'a:tz?:', a:tzem?'j, 'a:x?:lh',
'a:xt?m', 'a:x?:x', a:'h?la', a:'j, a:'jm?, a:'jnan?:,
a:'jtz?:, a:'jtzanan?:, a:'kn?:]
In the QListWidget created by this code, I see only items
corresponding to those elements that do not contain accented vowels
(here, those that don't contain ?, ?, etc.); items that
correpsond to strings with accented vowels are left empty. Further
experimentation with addItem( ), addItems(), and insertItem( ) show
that any string that contains an non-ASCII character results in an
empty Item being inserted into the QListWidget.
Any ideas about what is going on would be appreciated.
Are you 100 % sure that unicode is handled properly while reading the
xml? I never had problems with unicode and PyQt but I strictly using
unicode strings only in my apps.
This for example works for me (Python 2.7):
# -*- coding: utf-8 -*-
if __name__ == __main__:
import sys
from PyQt4.QtGui import *
app = QApplication(sys.argv)
list_widget = QListWidget()
list_widget.addItem(u??^? l? l?)
list_widget.show()
app.exec_()
Yes, it seems to be independent of the XML. For instance, I get the same
thing when I run the little app below (the GUI is generated by pyuic4):
import sys
from PyQt4 import QtCore, QtGui
try:
_fromUtf8 = QtCore.QString.fromUtf8
except AttributeError:
_fromUtf8 = lambda s: s
class Ui_UTFWidget(object):
def setupUi(self, UTFWidget):
UTFWidget.setObjectName(_fromUtf8(UTFWidget))
UTFWidget.resize(400, 300)
self.centralWidget = QtGui.QWidget(UTFWidget)
self.centralWidget.setObjectName(_fromUtf8(centralWidget))
self.listWidget = QtGui.QListWidget(self.centralWidget)
self.listWidget.setGeometry(QtCore.QRect(17, 9, 362, 241))
self.listWidget.setObjectName(_fromUtf8(listWidget))
UTFWidget.setCentralWidget(self.centralWidget)
self.menuBar = QtGui.QMenuBar(UTFWidget)
self.menuBar.setGeometry(QtCore.QRect(0, 0, 400, 22))
self.menuBar.setObjectName(_fromUtf8(menuBar))
self.menuUTF_test = QtGui.QMenu(self.menuBar)
self.menuUTF_test.setObjectName(_fromUtf8(menuUTF_test))
UTFWidget.setMenuBar(self.menuBar)
self.mainToolBar = QtGui.QToolBar(UTFWidget)
self.mainToolBar.setObjectName(_fromUtf8(mainToolBar))
UTFWidget.addToolBar(QtCore.Qt.TopToolBarArea, self.mainToolBar)
self.statusBar = QtGui.QStatusBar(UTFWidget)
self.statusBar.setObjectName(_fromUtf8(statusBar))
UTFWidget.setStatusBar(self.statusBar)
self.menuBar.addAction(self.menuUTF_test.menuAction())
self.retranslateUi(UTFWidget)
QtCore.QMetaObject.connectSlotsByName(UTFWidget)
def retranslateUi(self, UTFWidget):
UTFWidget.setWindowTitle(QtGui.QApplication.translate(UTFWidget,
UTFWidget, None, QtGui.QApplication.UnicodeUTF8))
self.menuUTF_test.setTitle(QtGui.QApplication.translate(UTFWidget,
UTF test, None, QtGui.QApplication.UnicodeUTF8))
class MyForm(QtGui.QMainWindow):
def __init__(self, parent=None):
QtGui.QWidget.__init__(self, parent)
self.ui = Ui_UTFWidget()
self.ui.setupUi(self)
self.ui.listWidget.addItem(abcde)
