You must import the JavaFX library (only rendering supported) with Processing 4:

```auto
import processing.javafx.*;

void setup()
  {
  size(200, 200, FX2D);
  }
  
void draw()
  {  
  }

```

See related issues with JavaFX and Processing 4:

- [Error trying to import JavaFX classes in Processing 4 · Issue #15 · processing/processing4-javafx · GitHub](https://github.com/processing/processing4-javafx/issues/15)

Some work arounds:

> i’m trying to use processing 4 because it’s needed for Unfolding 0.9.6 library for javafx

Are you referring to this? This is a _[fork](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/working-with-forks/fork-a-repo)_ and I do not use this version.

- [GitHub - jimbok8/unfoldingFX: Integration of unfolding with JavaFX. A library to create interactive maps and geovisualizations in Processing and Java](https://github.com/jimbok8/unfoldingFX)

You must clearly communicate what library you are using and provide a link if unclear.  
In this case the Unfolding FX fork above (10 years old) may not be supported.

I do not use the Unfolding FX fork and can’t comment on it or support it.

This is the current Unfolding library 0.9.6 listed in Processing 4 and it states _not compatible_:

The latest Unfolding 0.9.92 link is available here and I am using it with success in Processing 4.3:

- [Template with examples not working · Issue #167 · tillnagel/unfolding · GitHub](https://github.com/tillnagel/unfolding/issues/167)

If I try to use the FX2D renderer with the 0.9.92 version in Processing 4.3 IDE there are issues with scrolling with mouse wheel.  
I was able to scroll with the numpad + and - keys. `:)`

Scrolling issue with FX2D that seems to have carried over to Processing 4:

- [mouseWheel() not working when using FX2D renderer · Issue #4169 · processing/processing · GitHub](https://github.com/processing/processing/issues/4169)

Have fun with this!
