Strange problem just cropped up, not sure what is going on. I have a
QTextEdit box where I'm funneling python logging messages.
self.__textEdit = QtGui.QTextEdit(self)
self.__textEdit.setReadOnly(True)
self.__textEdit.document().setMaximumBlockCount(100)
self.__textEdit.setLineWrapMode(QtGui.QTextEdit.NoWrap)
class QtStreamHandler(logging.Handler):
def __init__(self,parent):
logging.Handler.__init__(self)
self.__textWidget = parent
self.__formater = logging.Formatter("%(levelname)-10s
%(message)s")
def createLock(self):
self.__mutex = QtCore.QMutex()
def acquire(self):
self.__mutex.lock()
def release(self):
self.__mutex.unlock()
def emit(self,record):
self.__textWidget.append(self.__formater.format(record))
self.__textWidget.ensureCursorVisible()
This line is causing the error.
self.__textWidget.append(self.__formater.format(record))
It doesn't matter what I put in, I tried a string literal, got same error.
self.__textWidget.append("bob")
Error:
QObject::connect: Cannot queue arguments of type 'QTextCursor'
(Make sure 'QTextCursor' is registed using qRegisterMetaType().)
It only happens once. From what I can see its not dropping any messages
either.. Google turns up nothing, just some speculation on a threading
problem.
