Hi, I'm writing a simple text editor in PyQT4. It works for ASCII
characters but I use UTF-8 encoded files with non-ASCI characters like
Polish letters (łóżźć etc.) I've used the "simple" way:
###########################
import sys
from PyQt4 import QtCore, QtGui
from edytor import Ui_notatnik
class StartQT4(QtGui.QMainWindow):
def __init__(self, parent=None):
QtGui.QWidget.__init__(self, parent)
self.ui = Ui_notatnik()
self.ui.setupUi(self)
QtCore.QObject.connect(self.ui.button_open,QtCore.SIGNAL("clicked()"),
self.file_dialog)
QtCore.QObject.connect(self.ui.button_save,QtCore.SIGNAL("clicked()"),
self.file_save)
def file_dialog(self):
fd = QtGui.QFileDialog(self)
self.filename = fd.getOpenFileName()
from os.path import isfile
if isfile(self.filename):
text = open(self.filename).read()
self.ui.editor_window.setText(text)
def file_save(self):
from os.path import isfile
if isfile(self.filename):
file = open(self.filename, 'w')
file.write(self.ui.editor_window.toPlainText())
file.close()
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
myapp = StartQT4()
myapp.show()
sys.exit(app.exec_())
##############################
It works ok for ASCI characters but when I open a file with Polish
letters they aren't displayed properly (textEdit) - also saving a file
with such letters won't save them correctly.
Similar with QFile:
##############################
# -*- coding: utf-8 -*-
import sys
from PyQt4 import QtCore, QtGui
from edytor import Ui_notatnik
class StartQT4(QtGui.QMainWindow):
def __init__(self, parent=None):
QtGui.QWidget.__init__(self, parent)
self.ui = Ui_notatnik()
self.ui.setupUi(self)
QtCore.QObject.connect(self.ui.button_open,QtCore.SIGNAL("clicked()"),
self.file_dialog)
QtCore.QObject.connect(self.ui.button_save,QtCore.SIGNAL("clicked()"),
self.file_save)
def file_dialog(self):
fd = QtGui.QFileDialog(self)
self.filename = fd.getOpenFileName()
from os.path import isfile
if isfile(self.filename):
s = QtCore.QFile(str(self.filename))
s.open(QtCore.QIODevice.ReadOnly)
self.ui.editor_window.setPlainText(str(s.readAll()))
s.close()
def file_save(self):
from os.path import isfile
if isfile(self.filename):
s = QtCore.QFile(str(self.filename))
s.open(QtCore.QIODevice.WriteOnly)
s.writeData(str(self.ui.editor_window.toPlainText()))
s.close()
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
myapp = StartQT4()
myapp.show()
sys.exit(app.exec_())
#######################################
but when I try to save the file with Polish letters I get:
UnicodeEncodeError: 'ascii' codec can't encode characters in position
20-23: ordinal not in range(128)
