Graph (nodes, edges) Drawing in Qt
I need to visualize a schematic transit map of a rail network in real time using C++ (Qt/Linux). To do that first I need to read the real coordinates of track elements (tracks, crossing, signals, stations etc) from main memory and then dynamically generate the corresponding graph elements over a Cartesian plane (like the parallel lines in the example picture below). So far I was unable to implement this graph in Qt (As far as I know there is no Qt library for graph drawing!!) :crying:
Is Qt is good for this kind of problem?
How can I read memory objects within Qt framework?
It would be highly appreciated if someone could refer me few example links/repos of similar (graph, network, circuit, mesh) problems done with Qt.

What exactly do you consider a "memory object"?

Such graph as in your attachment should easily be created with Graphics View. If you need help with the graph itself, any C++ graphing library should work. Then it's just a matter of visualizing the graph in Qt.
