[PyKDE] GroupBox attributes- raised vs flat

[Tony Cappellini]

Is it normal for the Top edge of a Group Box to be visible, when the
Flat attribute is set to True?

See these screenshots

I need to use a container for that Button, that is not visible.
Is there a container I can use which will not be visible, but the
widgets within it are visible?
