Qt : I have Subclass the Qgraphicsview and handling mouse events and Set the Dragmode as RubberBandDrag
setDragMode(QGraphicsView::RubberBandDrag);
I am getting the rubberband selection but I am not able to customize the rubberband selection color. Please suggest .....
I guess that will take the system color.
The cleanest way to do it is by subclassing QRubberBand or, better, create your own rubber band as a QWidget containing a QRubberBand (allows you to customize even more the rubber band).
Take look at this question, it made my day sometime ago.
If you are going to write cross-platform code, keep in mind that on recent osX versions cocoa does not draw the size grips, so you have to draw them in your paint event (under #ifdef Q_OS_MAC).
