python - 在 threading.Thread 对象中使用 PySide.QtCore.Signal

Question

我正在使用这样的东西：

import threading
from PySide import QtCore

class Smt(threading.Thread):
    foo_signal = QtCore.Signal(object)

    def __init__(self):
        threading.Thread.__init__(self)

    def run(self);
        while True:
            pass # and so..

然后我开始它：

a = Smt()
a.foo_signal.connect(function)
a.start()

输出是：

AttributeError: 'PySide.QtCore.Signal' object has no attribute 'connect'

如果我使用QtCore.QThread而不是threading.Thread- 它效果很好。但我不想使用QThread.

甚至可能吗？

Answer 1

Signals require that the class which is using them be inherited from a QObject (Or any class which also inherits QObject). So you can either switch to using a QThread or also inherit from QObject and call QtCore.QObject.__init__(self) in your __init__
