I'm not sure what exactly your problem is - I had no problem running a
slightly modified version of your script. I don't have a version of Qt
with a QPlainTextEdit, so I used a plain QTextEdit instead ('scuse the
play on words). I also modified the thread run method slightly, like
so...
def run(self):
s = self.currentThreadId()
for i in range(10):
self.log.info("Thread %s (%d)", s, i)
self.sleep(1)
With these changes (and replacing the appendPlainText with just plain
append, the script worked fine. I was able to get messages from
multiple running threads and the main window/log window into the
single QTextEdit.
My testing was conducted on Kubuntu Hardy with SIP 4.7.9 and PyQt
4.4.4. The modified script is at
