Need help in creating an adjacency graph

  • Hi everyone,
    I need to create an adjacency graph and find the shortest path using Boost library (BGL) ! I'm a complete amateur and it's a huge challenge for me !
    Let's take this adjacency graph as an exemple
    alt text

    Let's start with these questions
    1-How can I create each node and name it ? ( A , B ,C ...)
    2-How to connect nodes with arrows or lines ?
    3-How can I give values to each line/arrow ?
    I couldn't find any tutorials related to this I wish someone helps me

  • @Codeseeker sorry but how is this related to Qt? in addition to using BGL library to solve the graph algorithms, are you planning to draw the graph?

    What about this tutorial?

  • Why Boost library?- This is a Qt forum, and of course, you can create a graph in Qt, even in plain C++ with Winapi.

    Once I created a similar project and I recommend you to think about your architecture:

    • You create a Vertex class with x,y, and ID properties; also a GraphManager class to store all the vector that you can create.

    • You create a Edge class , and also create a container to this Edges (every Edge has a first and second id to connect vertex).

    • This is answered with point number 2.

    Recommendation: Create a graph view, and create a graph manager to store all the containers that you'll need.

    This is a whole process, I think is quite big to answer it in one forum post.
