Animation showing a node scene with nodes being created and edited

Interacting with a sample node scene#


To install QNodeEditor, use the following command to install the package from PyPi:

pip install QNodeEditor

Alternatively, you can clone and install the source code from the Github repository:

git clone https://github.com/JasperJeuken/QNodeEditor.git

pip install -e .



The QNodeEditor package aims to provide flexible tools for making any sort of node editor you can imagine. The package provides a structure for interacting with and evaluating a node scene. This scene will contain nodes that you can easily define yourself.

All nodes consist of various entries, which can have an input or output socket (or neither). The package comes with a few pre-defined entries, such as one with simple label, or a value selector (int or float). However, it is trivial to create your own entries with any widget(s) you need.

The evaluation of node scenes happens asynchronously. For longer computations this avoids the interface from freezing. Any errors that are throws during evaluation are caught and forwarded, such that they can be handled by you.
