Stahl jsem si jednoduchy priklad pro praci s QThread. Priklad funguje bez
problemu, tak jsem ho zacal upravovat. Bohuzel jsem zjistil, ze to v PyDev
nejde ladit. Nevite nekdo jak na to? Kdyz to nejde s PyDev, jde to necim jinym?
Priklad:
#import pydevd
#pydevd.connected = True
#pydevd.settrace()
from PySide import QtCore
import time, sys
class MyWorkerThread(QtCore.QThread):
message = QtCore.Signal(str)
def __init__(self, id, parent=None):
super(MyWorkerThread, self).__init__(parent)
self.id = id
def run(self):
for i in range(10):
self.message.emit("%d: %d" % (self.id, i))
time.sleep(0.2)
class MainProgram():
def __init__(self, parent=None):
self.threads = []
self.addWorker(MyWorkerThread(1))
self.addWorker(MyWorkerThread(2))
def addWorker(self, worker):
worker.message.connect(self.printMessage, QtCore.Qt.QueuedConnection)
# connect the finished signal to method so that we are notified
worker.finished.connect(self.workersFinished)
self.threads.append(worker)
def startWorkers(self):
for worker in self.threads:
print worker.id
worker.start()
# no wait, no finished. you start the threads and leave.
def workersFinished(self):
if all(worker.isFinished() for worker in self.threads):
# wait until all the threads finished
QtCore.QCoreApplication.instance().quit()
@QtCore.Slot(str)
def printMessage(self, text):
sys.stdout.write(text+'\n')
sys.stdout.flush()
if __name__ == '__main__':
app = QtCore.QCoreApplication(sys.argv)
m = MainProgram()
m.startWorkers()
sys.exit(app.exec_())
