Usage

How to create the UI with tknodesystem?

The workflow is very simple:

• place the NodeCanvas widget in your application,
• add the NodeMenu,
• store the node types in the menu (using .add_node),
• write commands/functions and values for the node types,
• run the script, spawn the nodes through the node menu and play.

You can also place nodes in the canvas by default.

Basic Example

from tknodesystem import *
import tkinter

root = tkinter.Tk()

# Add Node Canvas
canvas = NodeCanvas(root)
canvas.pack(fill="both", expand=True)

# Place some default nodes in the canvas
NodeValue(canvas, x=0, y=10) # x and y are not necessary arguments
NodeOperation(canvas, x=150, y=1)
NodeCompile(canvas, x=300, y=10)

# Add the NodeMenu and spawn new nodes.
menu = NodeMenu(canvas) # right click or press <space> to spawn the node menu
menu.add_node(label="NodeValue", command=lambda: NodeValue(canvas))
menu.add_node(label="NodeOperation", command=lambda: NodeOperation(canvas))
menu.add_node(label="NodeCompile", command=lambda: NodeCompile(canvas))

root.mainloop()
