NodeEditor is conceived as a general-purpose Qt-based library aimed at graph-controlled data processing. Nodes represent algorithms with certain inputs and outputs. Connections transfer data from the output (source) of the first node to the input (sink) of the second one.

NodeEditor framework is a Visual Dataflow Programming tool. A library client defines models and registers them in the data model registry. Further work is driven by events taking place in DataModels and Nodes. The model computing is triggered upon arriving of any new input data. The computed result is propagated to the output connections. Each new connection fetches available data and propagates is further.

Each change in the source node is immediately propagated through all the connections updating the whole graph.

• OSX (Apple Clang - LLVM 3.6), Linux (x64, gcc-5.0, clang-3.8):
• Windows (Win32, x64, msvc2015, MinGW 5.3):

• Qt >5.2
• CMake 3.2

• Model-based nodes
• Automatic data propagation
• Datatype-aware connections
• Embedded Qt widgets
• One-output to many-input connections
• JSON-based interface styles
• Saving scenes to JSON files

1. Extend set of examples
2. GUI: fix scrolling for scene view window scrolling
3. Implement grouping nodes
4. Split graph and GUI parts
5. Build data propagation on top of the graph code

Chigraph is a programming language for beginners that is unique in that it is an intuitive flow graph:

It features easy bindings to C/C++, package management, and a cool interface.
