示例1: test_methodinvoke
# 需要导入模块: from AnyQt.QtCore import QCoreApplication [as 别名]
# 或者: from AnyQt.QtCore.QCoreApplication import processEvents [as 别名]
def test_methodinvoke(self):
executor = ThreadExecutor()
state = [None, None]

def func(callback):
callback(QThread.currentThread())
obj = StateSetter()
f1 = executor.submit(func, methodinvoke(obj, "set_state", (object,)))
f1.result()
# So invoked method can be called
QCoreApplication.processEvents()
self.assertIs(state[1], QThread.currentThread(),
"set_state was called from the wrong thread")
self.assertIsNot(state[0], QThread.currentThread(),
"set_state was invoked in the main thread")
executor.shutdown(wait=True)示例2: TestTask
