What happens when you assign it to its own string. Do you get error while
assigning it to string or when using that string with file dialog?
2011/7/23 Martin Airs camberw...@gmail.com
Good day all,
In this test case script I have added at the bottom, It bombs with this
error...
[martin@desktop python]$ python testcase.py
Traceback (most recent call last):
File testcase.py, line 17, in pressed
filename = QtGui.QFileDialog.getOpenFileName(self, 'Open file',
os.path.split(self.lineedit.text())[0], logs)
File /usr/lib64/python2.7/posixpath.py, line 83, in split
i = p.rfind('/') + 1
AttributeError: 'QString' object has no attribute 'rfind'
I cant quite work out why, if I take the
*os.path.split(self.lineedit.text())* out and put it on a seperate line
assigning it to its own
string it still doesn't work
I wonder if anyone could show me how to get round this, please
Thanks in advance
Martin Airs

[PyQt] translation of ui

You don't need to mark strings in UI files. Just use pylupdate4 on UI files as you would use it on python files, and translations will be extracted from UI files, too. If you load or compile UI files, PyQt generates the necessary code to translate the user interface.

[PyQt] safely closing QThread when application exits.
hi, I am pyqt beginner and followed tutorials on the internet to learn it until recently. Then I have wanted to develop my own application. I am developing a simple chat application. I want to have 2 windows running independently (in other words two separate applications), one for server and one for client. When server starts to run, it is going to wait for client to run, and they will chat. So far, I could only start doing server side. I am using QThread, which is a subject rather unclear to me. I am getting this error when I close my application from X button: QThread: Destroyed while thread is still running I am guessing that this occurs because I am not closing the thread safely before application exists. I was wondering how I can make my thread respond to application exist so that it can close itself.

If you have read my earlier post, I was doing a simple chat application. Here is how it goes. You're not converting your data correctly. On the sending side you do it properly, decoding to utf-8 and then sending the bytes through the network. On the receiving side you're using Python's socket API, which gives you a byte-stream and then create a QString from it implicitly. That uses whatever your systems default-encoding is to decode the bytes into a string. The error is in NetConnectorWorker.run, but its not that easy to fix since you currently do not send the amount of bytes you cannot know on the receiving side wether all data has been received or not and hence you cannot do a correct decoding. I suggest to switch to use Qt's network stack, that'll make these things a bit easier since you can use QDataStream on the network socket which handles sending QString's just fine. If thats not possible, you'll have to add the length of the message into the byte-stream or always read up to the first \n and decode the content then and make sure the sender always sends at least 1 \n.
