I am trying to understand how to run a second event loop using a qthread. The
Qt docs indicate this is possible, but I haven't found any examples. I have a
simple example that I think should work, but doesn't. When I run my thread's
exec_(), it blocks. The actual application I am writing calls the qApp's
exec_ before the thread's exec_, but even then the thread's exec_ blocks
further execution. Does anyone know how to do this?
Thanks,
Darren
from PyQt4 import QtGui, QtCore
import time
class Dispatcher(QtCore.QThread):
def __init__(self, parent=None):
QtCore.QThread.__init__(self, parent)
self.timer = QtCore.QTimer(self)
self.connect(self.timer,
QtCore.SIGNAL("timeout()"),
self.update)
self.timer.start(20)
def update(self):
self.emit(QtCore.SIGNAL('update(string)'), str(time.time()))
app = QtGui.QApplication(['test'])
text = QtGui.QLabel('Hi')
a = Dispatcher()
text.connect(a,
QtCore.SIGNAL('update(str)'),
text,
QtCore.SLOT('setText(string)'))
a.exec_()
text.show()
app.exec_()
