Hello, I have a pyqt4 code in which i'm trying the signal/slot mechanism. The (stripped) code is as follows:
class D(QtCore.QThread): def __init__(self): QtCore.QThread.__init__(self) tpl = ("Primary", "priSec") print "tpl:", tpl self.emit(QtCore.SIGNAL("setLabel"), tpl) class Gui(QtGui.QDialog): def __init__(self, parent = None): QtGui.QDialog.__init__(self, parent) def setLabel(self, tpl): print "####tpl:", tpl print "**********tpl:", str(tpl) return if __name__ == "__main__": app = QtGui.QApplication(sys.argv) dialog = Gui() d = D() QtCore.QObject.connect(d, QtCore.SIGNAL("setLabel"), dialog.setLabel, QtCore.Qt.QueuedConnection) sys.exit(dialog.exec_()) The output i'm getting is as follows: tpl: ('Primary', 'priSec') ####tpl: (<refcnt 0 at 0xb7caac8c>,) **********tpl: ((((((((<NULL>,),),),),),),),) Can anyone kindly tell me what's happening here? Why is the tuple ("Primary", "priSec") getting converted to this <NULL> thingy? And what is this thingy anyways (It looks to be a deeply nested tuple, but am not sure). Thanks a lot! -- warm regards, Pradnyesh Sawant -- Be yourself, everyone else is taken. --Anon -- http://mail.python.org/mailman/listinfo/python-list
