Hi,
I am havin an encoding problem. If you have read my earlier post, I was
doing a simple chat application. Here is how it goes.
===
Client Class
===
def on_lineEdit_returnPressed(self):
text= self.ui.lineEdit.text()
self.ui.lineEdit.selectAll()
self.ui.lineEdit.cut()
self.ui.textEdit.paste()
self.netconnector.sendMessage(text)
===
netconnector
===
def sendMessage(self,msg):
if self.isConnected:
self.socket.send(msg.toUtf8().trimmed())
===
Server Side:
===
===
Server Class
===
self.connect(self.netconnector,QtCore.SIGNAL("dataRecieved(QString)"),self.messageRecieved)
===
server side netconnector:
===
def messageRecieved(self,data):
self.ui.textEdit.append(data)
What happens is that, when I type non-ascii characters into client side line
edit, it becomes distorted at server side, like
şğü -- > ÅÄü
Any idea how to fix this?
You can find whole code as attachment.
