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!
