Implementing flowgraph inside a flowgraph application
I am about to start my 3rd major Qt project and this time the idea is to develop a tool where each node in a flowgraph will have a flowgraph in itself. I plan to create a main QGraphicsScene with QGraphicsScene per flowgraph node individually. Each node could be a QGraphicsWidget thus solving the issue of dependency between nodes.
As an analogy the use case is : A course comprises of assignments(one node in the main flowgraph) where each assignment comprises of some sub-assignments (another flowgraph). The sub-assignments are chained while the assignments can have some dependency among themselves.
Is my idea of implementation correct or could you'll suggest me a better approach.
Thanks in advance.
