The toggled signal is defined as: void QAbstractButton::toggled ( bool 
checked )
Use  QtCore.SIGNAL("toggled(bool)") instead of 
QtCore.SIGNAL("toggled()") and it will work as expected.
Because a QCheckBox can be a tri-state checkbox , it's better to use 
stateChanged(int) instead of toggled(bool).
