我是 Qt 的新手,我试图在 python 子进程中执行一个程序:
class MiThread(threading.Thread):
def __init__(self):
threading.Thread.__init__(self)
def run(self):
try:
from Queue import Queue, Empty
except ImportError:
#from queue import Queue, Empty # python 3.x
print "error"
ON_POSIX = 'posix' in sys.builtin_module_names
def enqueue_output(out, queue):
for line in iter(out.readline, b''):
queue.put(line)
out.close()
p= Popen(["java -Xmx256m -jar bin/HelloWorld.jar"],cwd=r'/home/karen/sphinx4-1.0beta5-src/sphinx4-1.0beta5/',stdout=PIPE, shell=True, bufsize= 4024)
q = Queue()
t = Thread(target=enqueue_output, args=(p.stdout, q))
print "estoy en el hilo"
t.daemon = True # thread dies with the program
t.start()
但是当我执行它失败并出现以下错误:
QObject::connect: Cannot queue arguments of type 'QTextCursor'
(Make sure 'QTextCursor' is registered using qRegisterMetaType().)
我该如何解决?
