[PyQt] Get class 's children on init

[panoss]

class DataForm(QtGui.QGroupBox):
   def __init__(self, parent, task=None):
       QtGui.QWidget.__init__(self, parent)   

       self.labelHello = QtGui.QLabel(self)
       self.labelHello.setText("This is My Widget")


       children = self.children()

I 'm trying to get the children in the init of the class.
It' a GroupBox with two text boxes in it.
But it gets no children, returns empty.
