Documentation/sample about linking nodes programmatically #21

Closed Paolo-Oliverio closed 4 weeks ago

Paolo-Oliverio commented 2 months ago

Some things seems to be missing from the actual documentation like the possibility to add links programmatically to nodes. I need to serialize and deserialize nodegraphs so I need to recreate connections programmatically.

It would be great to have a more complex example that show off the entire api some kind of imgui demo but for imNodeFlow.

It is possible to create links, this was also visible in the old demo video. It's indeed not very well documented and I'll fix that.

auto n = INF.placeNode<DemoNode7>();
auto m = INF.placeNode<DemoNode3>();
n->inPin("Val")->createLink(m->inPin("X"));

this is a little snapshot from my testing code, I hope this helps.

One day I'll take the time and build a complete example with a bit of everything. Also as part of the to-do list of this project, there is the goal of creating helpers to export everything as some sort of JSON and the respective import helper. But I don't have the time to work on it now. So if you have to create such methods for your code consider opening a PR if you are interested.

Did the code snippet work for you? Also, how is it going with the nodes serialization and deserialization?

Paolo-Oliverio commented 2 months ago

Code worked great , serialization is on backlog I don't think it will be an issue. I'm pretty busy at the moment with business logic so frontend is on pause. A major pain point is the issue about rendering many nodes , it shouldn't be hard to fix but I touched imgui rendering too long ago to find a quick solution.

Will be added in future example folder
