Node editor demo expanded #561

Open hwps opened 1 year ago

hwps commented 1 year ago

This PR expands on the node editor demo to make it a functional example of a node-based UI.

Features:

multiple node types
multiple connector types
linking between connectors of the same type
detaching and reattaching links
getting value from linked node if slot is connected

node_editor

Some notes:

only tested with the glfw_opengl3 backend
uses system malloc, not sure if nk_malloc should be preferred.
uses the standard panel close button , then checks for NK_WINDOW_HIDDEN whether to delete a node or display it. Not sure if there's some pitfall here.

Nice stuff

I like where this is going. I'm not sure what's wrong with the demo though? This is the sdl_renderer.... Screenshot at 2023-09-12 03-25-01

@RobLoach Can you click the connectors to draw a link or right click to add nodes?

Maybe there should be some more nodes or at least links in the initial state. I realize now that for someone not used to a node-based UI it might be non-obvious what to do.

Ok, finally did this slight update to the init state. Screenshot attached.

Nice work! I ran it on glfw_opengl3 and x11_xft demos (screenshot for the later below)
