[PyKDE] Non disappearing label

[Derek Fountain]

If I have a frame, inside which I put a label arranged via a vertical layout 
box, then call this code:

contentsFrameLayout = self.contentsFrame.layout()
contentsFrameLayout.remove( self.labelWidget )
del self.labelWidget

wouldn't I expect the label to disappear off screen? Because it doesn't, and 
that puzzles me... :o}

The remove() simply removes the widget from the set managed by the layout 
manager. You need to remove the labelWidget from its parent. See the FAQ 
entry on deleting the children of QObjects.

I don't have any ideas about the reasoning behind this..
