PySide: Easier way of updating GUI from another thread

I started coding with PySide recently and I needed a equivalent of PyGObject's GLib.idle_add behaviour. I based the code off of your answer ( https://stackoverflow.com/a/11005204/1524507 ) but this one uses events instead of using a queue ourselves.

from PySide import QtCoreclass InvokeEvent(QtCore.QEvent):    EVENT_TYPE = QtCore.QEvent.Type(QtCore.QEvent.registerEventType())    def __init__(self, fn, *args, **kwargs):        QtCore.QEvent.__init__(self, InvokeEvent.EVENT_TYPE)        self.fn = fn        self.args = args        self.kwargs = kwargsclass Invoker(QtCore.QObject):    def event(self, event):        event.fn(*event.args, **event.kwargs)        return True_invoker = Invoker()def invoke_in_main_thread(fn, *args, **kwargs):    QtCore.QCoreApplication.postEvent(_invoker,        InvokeEvent(fn, *args, **kwargs))

Which is used the same way in the above answer link.

This is what I have so far. I wrote the following code somewhere in a helper module:

from Queue import Queueclass Invoker(QObject):    def __init__(self):        super(Invoker, self).__init__()        self.queue = Queue()    def invoke(self, func, *args):        f = lambda: func(*args)        self.queue.put(f)        QMetaObject.invokeMethod(self, "handler", QtCore.Qt.QueuedConnection)    @Slot()    def handler(self):        f = self.queue.get()        f()invoker = Invoker()def invoke_in_main_thread(func, *args):    invoker.invoke(func,*args)

Then my threads can very easily run code to update the GUI in the main thread. There is no need to create and connect signals for every operation.

class MyThread(threading.Thread):    def __init__(self):        super(IconThread, self).__init__()        # ...    def run(self) :        # ...        # Need to update the GUI        invoke_in_main_thread(self.item.setIcon, icon)

I think something like this is quite nice.
