JEditorPane z JavaScript i CSS wsparcia

Question

pracuję nad Swing za pomocą JEditorPane ale to nie wspiera JavaScript lub jakąś zaawansowaną tag jak <object> itd., A nie wspieranie kolor, styl czcionki itp

Czy jest więc jakieś rozwiązanie że okienko edytora może wyświetlać plik HTML wyświetlany w normalnej przeglądarce HTML?

Answer 1

• prąd Java6/7 wspieranie tylko (do września) Html 3.2 o ograniczonej wsparciem dla css,

• dla Html5 i dość pełny css support używać JavaFx Components,

• istnieje zwyczaj Java biblioteki z (pełna? ??) obsługa HTML4/5, css i js, ale proponuję użyć JavaFX zamiast

Answer 2

+1 do mKorbel.

Użyj JavaFXWebView, która obsługuje HTML5, integrując go z Swingiem.

Oto przykład:

import java.awt.*; 
import java.awt.event.*; 
import java.net.MalformedURLException; 
import java.net.URL; 
import javafx.application.Platform; 
import javafx.beans.value.ChangeListener; 
import javafx.beans.value.ObservableValue; 
import static javafx.concurrent.Worker.State.FAILED; 
import javafx.embed.swing.JFXPanel; 
import javafx.event.EventHandler; 
import javafx.scene.Scene; 
import javafx.scene.web.WebEngine; 
import javafx.scene.web.WebEvent; 
import javafx.scene.web.WebView; 
import javax.swing.*; 

public class SimpleSwingBrowser implements Runnable {

    private WebEngine engine; 

    private JFrame frame = new JFrame(); 
    private JPanel panel = new JPanel(new BorderLayout()); 
    private JLabel lblStatus = new JLabel(); 

    private JButton btnGo = new JButton("Go"); 
    private JTextField txtURL = new JTextField(); 
    private JProgressBar progressBar = new JProgressBar(); 

    private void initComponents() { 
     jfxPanel = new JFXPanel(); 

     createScene(); 

     ActionListener al = new ActionListener() { 
      @Override public void actionPerformed(ActionEvent e) { 
       loadURL(txtURL.getText()); 
      } 
     }; 

     btnGo.addActionListener(al); 
     txtURL.addActionListener(al); 

     progressBar.setPreferredSize(new Dimension(150, 18)); 
     progressBar.setStringPainted(true); 

     JPanel topBar = new JPanel(new BorderLayout(5, 0)); 
     topBar.setBorder(BorderFactory.createEmptyBorder(3, 5, 3, 5)); 
     topBar.add(txtURL, BorderLayout.CENTER); 
     topBar.add(btnGo, BorderLayout.EAST); 


     JPanel statusBar = new JPanel(new BorderLayout(5, 0)); 
     statusBar.setBorder(BorderFactory.createEmptyBorder(3, 5, 3, 5)); 
     statusBar.add(lblStatus, BorderLayout.CENTER); 
     statusBar.add(progressBar, BorderLayout.EAST); 

     panel.add(topBar, BorderLayout.NORTH);
