JUCE Framework Graph editing and visualisation

JUCE Graph Component

This is a JUCE Framework set of components that allows drawing a graph by connecting nodes and edges. The component is inspired by the plugin host demo application that comes with JUCE, but this one is a different implementation.

Features

• Each node can be scaled individually, zoom-in cmd + '+', zoom-out cmd + '-', or zoom to original scale cmd + '0'
• Multi-select using keyboard or mouse is supported
• Special type of node that can host any component
• Backed by a simple graph that supports communication between nodes
• Sample application to preview the component and how to use it
• Very simple theming for changing the overall components look and feel

Demo Application

• Right-click on the demo window to add example nodes, and drag pins to create edges
• Click and drag on the window to select multiple nodes and edges
• To scale a node, select it and hit cmd + '+', cmd + '-' or cmd + '0'
• Delete a node or edge by selecting it and hit delete or backspace
• Duplicate a node using cmd + 'd', duplicating host nodes is not supported yet

Building

The following steps are tested only on macOS:

• You will need a C++14 compiler
• Use the provided graph-viewer.jucer to generate a project for your platform or use the provided XCode project
• If you are generating a project from the jucer file, make sure you setup the correct JUCE modules paths correctly
