Qgraphicsscene/view connection line avoiding collision with other grapicsitems

[salcin]

Hi,

I want to connect two graphicsitems with a line in a graphicsscene. Right now, all I have is a straight line between the items. But I want to make the line go around other items in the view. It is OK for the line to cross another line.

Is there a standard way to do this in QT?

I have been thinking to use QGraphicsPathItem instead of the QGraphicsLineItem that I'm currently using for the line. But how do I choose the best way to route the line?


Thanks!

You need to implement an algorithm that calculates the route. This has nothing to do with Qt.

That was my suspicion. Thanks for the confirmation.
