flat : bool
This property holds whether the group box is painted flat or has a frame.
A group box usually consists of a surrounding frame with a title at the top. If this property is enabled, only the top part of the frame is drawn in most styles; otherwise the whole frame is drawn.
By default, this property is disabled; i.e. group boxes are not flat unless explicitly specified.
Note: In some styles, flat and non-flat group boxes have similar representations and may not be as distinguishable as they are in other styles.
Access functions:
bool isFlat () const
void setFlat ( bool flat )
