B4J Question Headless JavaFX in Console App

[xulihang]

JavaFX 26 has added support for headless mode: https://gluonhq.com/introducing-the-headless-platform-for-javafx/


Can we use JavaFX APIs like bitmap creator and canvas in a B4J console app?

It is useful to convert a ui app to a server app.

It does work, but not how you seem to think it does.
It is still a UI application; it just doesn't attempt to use any graphics output.
It's the same single threaded Javafx loop running (bad for servers), as a normal Javafx application.

It can still be useful as a console application that is started by the server for specific tasks. It was quite difficult to do with a regular UI app on Linux server: https://www.b4x.com/android/forum/t...-as-part-of-a-server-solution.123704/#content
