synchronize scrollbar in Qt

I have 2 graphicsview each with a separate scrollbar, as seen in the image. I wonder how I can synchronize, so that the move one the other moves too.

thanks

That is quite simple, just connect each view's scroll bar's valueChanged(int) signal (or sliderMoved(int)) signal to the other view's scroll bar's setValue(int) slot, like so:

connect(view1->horizontalScrollBar(), SIGNAL(valueChanged(int)), view2->horizontalScrollBar(), SLOT(setValue(int)));
connect(view2->horizontalScrollBar(), SIGNAL(valueChanged(int)), view1->horizontalScrollBar(), SLOT(setValue(int)));
