这是代码:
class MyWindowClass(QtGui.QMainWindow, form_class):
def __init__(self, parent=None):
GPIO.setmode(GPIO.BOARD)
GPIO.setup(26,GPIO.IN)
QtGui.QMainWindow.__init__(self, parent)
self.setupUi(self)
self.alarm_detect()
def alarm_detect(self):
getattr(self, "AlarmePerifericos").setVisible(False)
def alarme_perifericos(channel):
if not (GPIO.input(channel)):
getattr(self, "AlarmePerifericos").setVisible(True)
else:
getattr(self, "AlarmePerifericos").setVisible(False)
GPIO.add_event_detect(26, GPIO.BOTH, callback=alarme_perifericos)
app = QtGui.QApplication(sys.argv)
app.setStyle("GTK+") #Changing the style
myWindow = MyWindowClass(None)
myWindow.showFullScreen()
app.exec_()
我在Raspberry Pi中运行这个PyQt脚本。当程序检测到引脚26时,QObject" AlarmePerifericos"设置为可见,但我收到错误QCoreApplication::sendPostedEvents: Cannot send posted events for objects in another thread
。事情是,正如你所看到的,我不在另一个线程中。是什么造成的?你能救我吗?
谢谢。
