JFXHighlighter in Processing

Processing Coding Questions
1

Hello.

Has anyone used the JFoenix library with Processing. I am trying to make a text highlighter in a JavaFX TextArea. Since JavaFX doesn’t have one I tried using the JFoenix library without much success. After some research it seems that JFoenix and JavaFX API are incompatible?

This is the error i get.

java.lang.reflect.InaccessibleObjectException: Unable to make private com.sun.javafx.scene.text.TextLayout javafx.scene.text.Text.getTextLayout() accessible: module javafx.graphics does not “opens javafx.scene.text” to unnamed module @18be83e4

Did you mean JFXTextArea?

On my system (MacOS) the problem seems to be with JFXTextField. The following fails:

import com.jfoenix.controls.JFXTextField;
import javafx.scene.canvas.Canvas;
import javafx.scene.layout.StackPane;
import javafx.scene.layout.Pane;

void setup() {
  size(350, 200, FX2D);
  Canvas canvas = (Canvas)surface.getNative();
  StackPane root = (StackPane)canvas.getParent();
  Pane pane = new Pane();

  JFXTextField textField = new JFXTextField();
  println(textField);

  pane.getChildren().add(textField);
  root.getChildren().add(pane);
}

The following will run provided I use the latest .jar file. However, it fails if the searchField is added to VBox.

import com.jfoenix.utils.*;
import com.jfoenix.controls.*;

import javafx.scene.canvas.Canvas;
import javafx.scene.layout.StackPane;
import javafx.scene.layout.VBox;
import javafx.scene.layout.Pane;

Pane pane;
Canvas canvas;
StackPane root;
JFXHighlighter highlighter;

void setup() {
  size(700, 600, FX2D);
  background(#FFFFFF);
  surface.setTitle("JFXHighlighter Demo");
  canvas = (Canvas)surface.getNative();
  root = (StackPane)canvas.getParent();
  pane = new Pane();

  highlighter = new JFXHighlighter();
  println("highlighter",highlighter);
  JFXTextArea textArea = new JFXTextArea();
  println("textArea =",textArea);
  textArea.setPromptText("Type some text here...");
  textArea.setPrefRowCount(6);  
  // Search field
  JFXTextField searchField = new JFXTextField();
  println("searchField = ",searchField);
  searchField.setPromptText("Enter text to highlight");
  // Highlight button  
  JFXButton highlightBtn = new JFXButton("Highlight");
  println("highlightBtn =",highlightBtn);  
  highlightBtn.setOnAction(e -> {
    println("highlight btn hit.");
    String query = searchField.getText();
    if (query != null && !query.isEmpty()) {
      highlighter.clear(); // Clear previous highlights
      highlighter.highlight(textArea, query);
    }
  }
  );
  // Clear button
  JFXButton clearBtn = new JFXButton("Clear Highlights");
  clearBtn.setOnAction(e -> {
    highlighter.clear();
    println("clear btn hit.");
  });

  VBox vBoxMain = new VBox(textArea,  highlightBtn,  clearBtn); //searchField,
  vBoxMain.setStyle("-fx-padding: 15;");
  pane.getChildren().add(vBoxMain); 
  root.getChildren().add(pane);
}

The fix is supposedly to add:

–add-opens java.base/java.lang.reflect=ALL-UNNAMED

which may go in a gradle file. I tried adding it to Preferences.txt but it didn’t seem to help.

Output:
