Show JTable with JavaFX

Question

I would like to read numbers from a web page and use them in a program. This program displays a web page, but how do I display a table under a web page? And how do I populate a table with dates and prices from a web page.

import java.awt.BorderLayout; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.JScrollPane; import javax.swing.JTable; import javax.swing.JTextArea; import javax.swing.SwingUtilities; import javax.swing.table.AbstractTableModel; import javax.swing.table.TableModel; import javafx.application.Platform; import javafx.embed.swing.JFXPanel; import javafx.scene.Scene; import javafx.scene.paint.Color; public class Step4 { private void initAndShowGUI(final String url) { // This method is invoked on the EDT thread JFrame frame = new JFrame("Swing and JavaFX"); final JFXPanel fxPanel = new JFXPanel(); JPanel mainPanel = new JPanel(); mainPanel.setLayout(new BorderLayout()); mainPanel.add(fxPanel, BorderLayout.NORTH); TableModel dataModel = new AbstractTableModel() { private static final long serialVersionUID = -147208558114868864L; public int getColumnCount() { return 10; } public int getRowCount() { return 10;} public Object getValueAt(int row, int col) { return new Integer(row*col); } }; JTable table = new JTable(dataModel); JScrollPane tableContainer = new JScrollPane(table); JPanel display = new JPanel(); display.setLayout(new BorderLayout()); display.add(tableContainer, BorderLayout.CENTER); mainPanel.add(display, BorderLayout.SOUTH); frame.add(mainPanel); frame.pack(); frame.setSize(1000, 650); frame.setVisible(true); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); Platform.runLater(new Runnable() { @Override public void run() { initFX(fxPanel, url); } }); } private void initFX(JFXPanel fxPanel, String url2) { // This method is invoked on the JavaFX thread Scene scene = createScene(url2); fxPanel.setScene(scene); } private Scene createScene(String url2) { Scene scene = new Scene(new Browser_1(url2),750,500, Color.web("#666970")); return (scene); } public static void main(String[] args) { final String url = "https://www.tsp.gov/investmentfunds/shareprice/sharePriceHistory.shtml"; SwingUtilities.invokeLater(new Runnable() { @Override public void run() { Step4 s = new Step4(); s.initAndShowGUI(url); } }); } } class Browser_1 extends Region { final WebView browser = new WebView(); final WebEngine webEngine = browser.getEngine(); public Browser_1(String url) { //apply the styles getStyleClass().add("browser"); // load the web page webEngine.load(url); //add the web view to the scene getChildren().add(browser); } @SuppressWarnings("unused") private Node createSpacer() { Region spacer = new Region(); HBox.setHgrow(spacer, Priority.ALWAYS); return spacer; } @Override protected void layoutChildren() { double w = getWidth(); double h = getHeight(); layoutInArea(browser,0,0,w,h,0, HPos.CENTER, VPos.CENTER); } @Override protected double computePrefWidth(double height) { return 750; } @Override protected double computePrefHeight(double width) { return 500; } }

In circuit

• Add a suitable listener to the Worker background used by WebEngine .

• In this suitable listener, go to the Document Object Model of the webpage to get the results you are interested in, perhaps using the approach below.

• Build a TableModel that delivers results to JTable on demand, perhaps using the approach described below .

• Place a Swing event that calls setModel() with the updated TableModel ; the table is updated accordingly.

Based on this, below the InvalidationListener displays the result returned by getDocumentURI() .
