[Qt-interest] How to make rectangles dynamically in the empty spaceof a frame "like in FSView" ?

[Usman Ajmal]

Rather more appropriate will be to ask as to which class(es) of Qt does
FSView use to draw rectangles. It does seem to be using QGraphicsScene as
this class was i think not avalaible before Qt 4.

Thanks a lot.
