Hi
if you take a look for
http://doc.qt.io/qt-5/qtwidgets-graphicsview-diagramscene-example.html

It draw lines between object. You can use same code to do what you want.
You just need a line for each corner.
If I understand right what "trailing eges" means.

I think my requirement is different

not the requirement
the trailing lines should show dottled lines from start point to end
when mouseMovement

like the rectangle is moving

You can easy change the look of the line.
QPen QGraphicsLineItem::pen() const
