[Qt-interest] multiple QThread simultaneously

[NARCISO, Rui]

:p I know you can't _guess_ what's wrong ... before posting any code I wanted to make sure that it was possible "in theory" !!

Here's the code:

class DamasToTecplotThread(QThread):
    def __init__(self, dirList = [] ,rnaFile="", parent=None):
        QThread.__init__(self, parent)
        self.parent = parent
        self.dirList = dirList
        self.rnaFile = rnaFile
        
    def run(self):

        for dir, item in self.dirList:
            os.chdir(os.path.dirname(os.path.abspath(dir)))
            sys.argv = [sys.argv[0]] + ["-dir", dir, "-rna", self.rnaFile]
            damas2tecplot.run()
            self.emit(SIGNAL('tecplotConversionLaunched'), "Tecplot Conversion", \
                      os.path.join(os.path.dirname(os.path.abspath(dir)), 'POST_ALL',os.path.basename(os.path.abspath(dir))),  "", item, 10)

which is called like this:
                newThread = DamasToTecplotThread(dir, rnaFile, self)
                self.connect(newThread, SIGNAL('tecplotConversionLaunched'), self.addPostToCalculation, Qt.QueuedConnection)
                newThread.start()

and the error I get is:
Traceback (most recent call last):
  File "/home/cfdqdv2/to96665/TOOLS/EGADYT/integration/Version_1.0.5/CampaignManager/LibThread.py", line 96, in run
    self.emit(SIGNAL('tecplotConversionLaunched'), "Tecplot Conversion", \
TypeError: 'NoneType' object is not callable

any ideas ?

Yes, that should be possible, but if you want anyone to analyze "what's wrong" 
you should post a small working peace of your code at least, and the text of 
the error you get... if you think it's the signal you emit in the thread, try 
not to emit it and see if that really changes anything.

Remeber, we can't simply _guess_ what may be wrong without knowing your 
code :).
