Why such a longwinded api for something so simple.

QRect getFlowedRect( int index, const QSize & itemSize, int layoutWidth, int 
h_spacing, int v_spacing )
	int itemsPerRow = layoutWidth / (itemSize.width() + h_spacing);
	return QRect( QPoint( (index % itemsPerRow) * (itemSize.width() + h_spacing), 
(index / itemsPerRow) * (itemSize.height() + v_spacing) ), itemSize );

Seems to me that it's so simple it'd be better off put in a wiki and copy and 
pasted for people to use inline who need it.
