Hi,
I've been migrating some of my PyQt tools to the new Qt
setup with 6.3. For the most part its been straight forward but
Im having
problems with tools that utilizes worker threads. Specifically
when
I'm emitting signals from a worker QThread and connecting that
to my
Dialog thread.
If Im not connecting to the emitting signals in
the Dialog everything works fine. Any ideas what I'm doing
wrong? I added
an example that works fine in Nuke 6.2 with the old Qt setup but
instantly
crashes when it gets a signal in 6.3.
Cheers

Here is an example at pastebin,

Below is same example attached.
--------------------------------------------------------------------------
from PyQt4 import QtCore, QtGui
import time
class WorkerThread(QtCore.QThread):
progressEvent = QtCore.pyqtSignal(QtCore.QString)
def __init__(self,
parent=None):
super(WorkerThread, self).__init__(parent)
def
run(self):
self.progressEvent.emit('Starting processing..')
time.sleep(2)
self.progressEvent.emit('Finished
processing..')
class UserInterfaceDialog(QtGui.QDialog):
def __init__(self,
parent=None):
super(UserInterfaceDialog, self).__init__(parent)
self.workerThread =
WorkerThread()
self.workerThread.progressEvent.connect(self.setStatus)
self.statusBox =
QtGui.QTextEdit('Idle..')
self.startButton = QtGui.QPushButton('Start worker thread')
self.startButton.clicked.connect(self.startButtonClicked)
hBox =
QtGui.QVBoxLayout()
hBox.addWidget(self.statusBox)
hBox.addWidget(self.startButton)
self.setLayout(hBox)
def setStatus(self, statusMessage):
self.statusBox.setText(statusMessage)
def startButtonClicked(self):
self.workerThread.start()
dialog = None
def testNuke62():
from nukescripts import
pyQtAppUtils
def initPyQtDialog(pyQtApp):
app =
pyQtApp.getApplication(['UserInterfaceDialog'])
dialog =
UserInterfaceDialog()
dialog.show()
app.exec_()
pyQtApp = pyQtAppUtils.pyQtAppHelper(start =
True)
pyQtApp.run(initPyQtDialog, (pyQtApp,))
def testNuke63():
global dialog
dialog =
UserInterfaceDialog()
dialog.show()
testNuke63()
