_Journal of Parenteral and Enteral Nutrition_ (_JPEN_ ). No I don’t think you can get that in JavaFX.

nice one LOL 😂

Might be [JPen](https://jpen.sourceforge.net/html-home/index.html) (Java Pen Tablet Access Library)?

Since they provide the jar and OS dlls it should be possible although the library has not been updated for a long time

The problem is that opengl behaves weird, when it comes to various things, but thank you for the answer!

consider

```auto

// -------------------------------------------------------------------------------------------------------

void setup() {
  // size(1460, 850, P3D);
  fullScreen(P3D);

  surface.setTitle("Mondrian");

```

Are you aware that the Tablet library which you can install contains a jpen-2 jar file?

 ![tablet](https://canada1.discourse-cdn.com/flex036/uploads/processingfoundation1/original/3X/9/4/940167cbaf4ae7b87819779d29c4f7f8b60575a9.png)

that’s what chatGPT4 gave me

> You can create a simple progress bar in Processing using the `rect()` function to draw a rectangle that represents the progress. Here’s an example of how to create a basic horizontal progress bar:…

> In this example, we start with a progress bar of width zero and gradually increase its width in the `draw()` function. You can adjust the `progressBarWidth` increment and the `frameRate` to control the speed of progress.

```auto

//

int progressBarWidth = 0; // Initial progress bar width
int maxProgressBarWidth = 400; // Maximum width of the progress bar

void setup() {
  size(700, 100);
  frameRate(30); // Adjust the frame rate as needed
}

void draw() {
  background(220); // Set the background color

  // Update the progress bar width
  progressBarWidth += 2; // You can change this value to control the progress

  // Ensure the progress bar doesn't exceed its maximum width
  if (progressBarWidth > maxProgressBarWidth) {
    progressBarWidth = maxProgressBarWidth;
  }

  // Draw the progress bar outline
  stroke(0);
  noFill();
  rect(50, 40, maxProgressBarWidth, 20);

  // Draw the filled part of the progress bar
  fill(0, 128, 0); // Green color for the progress
  noStroke();
  rect(50, 40, progressBarWidth, 20);
}

```
