Hi all,
this may be a pure python question or QT related, I'm not sure:
I am having trouble with a decorated function not reporting back to the
main thread to drive progress bars etc.
When I remove the decorator and use the respective code directly in the
function in question it all works fine.
My code looks sort of like this (heavily simplified):
class ThreadManager(object):
def __init__(self, parent):
self.worker = Worker()
self.workerThread = QtCore.QThread(parent)
self.worker.moveToThread(self.workerThread)
def start(self):
self.workerThread.start()
class Worker(QtCore.QObject):
def myMethod(self):
someClassInstance.doHeavyLifting()
In my main code I connect signals from *someClassInstance* that indicate
progress during the heavy lifting, so that they drive progress bars in
the UI.
So far so good.
Now I am wanting to use a decorator on *myMethod(self)*, i.e.:
class Worker(QtCore.QObject):
@testDec
def myMethod(self):
someClassInstance.doHeavyLifting()
where testDec looks like this:
def testDec(fn):
def addTest(self):
print 'inside decorator', self
fn(self)
return addTest
The moment I do that, the threaded process does not report back to the
main thread, so the progress bars sit at 0% until the process returns,
then jump to 100%
What am I missing?
Cheers,
frank
