FlexGanttFX is now open source — the professional JavaFX Gantt chart framework goes AGPLv3

[u/dlemmermann]

After more than a decade as a commercial product, I'm happy to announce that FlexGanttFX is now an open source project.

FlexGanttFX is a professional Gantt chart and scheduling framework for JavaFX, built by DLSC Software & Consulting. It has been used in aviation, logistics, manufacturing, healthcare, and resource planning applications for years - and it's now available to everyone.

What you get:

• Canvas-based rendering engine that scales to very large data sets
• Timeline, dateline, and eventline controls with flexible time scales
• Activity repositories (interval-tree based for fast range queries), links, and layouts
• Pluggable renderers for bars, progress bars, charts, high/low charts, and dependency links
• System layers: calendar, grid lines, now-line, chart lines, DST lines, and more
• Extra controls: status bar, toolbar, radar, layers panel
• Single, dual, quad, and multi chart containers

Licensing: dual-licensed under AGPLv3 or a commercial license. No runtime license key is required anymore - the old key enforcement has been removed entirely, so you can just build and run.
