Browser using JEditorPane forcing blue background

Question

This is the code I'm using to display google in a JEditorPane

String url="http://google.com";    
editorPane.setEditable(false);
    try {
        editorPane.setPage(url);
    } catch (IOException e) {}

But for some reason the background will always be a blue colour, doesn't matter if I call

setBackgroundColor(Color.WHITE);

Foretell

For which component have you called setBackgroundColor(Color.WHITE);? You are setting background color of its parent. Please share some code. editorPane.setBackground(Color.WHITE); is work perfectly for me and I have added it into JScrollPane. – Katharina

I have tried it on both the editorpane and the container which contains it. I don't know what code I should add, there is no more relevant code besides creating the container, giving it a border layout, creating the editorpane and adding it to the container. The background is simply blue – Foretell

Try this one JTextPane text background color does not work. – Katharina

"This is the code I'm using to display google in a JEditorPane" The JEditorPane was never intended to render 'real world' HTML. Note that it only supports a subset of HTML 3.2 & (very) basic CSS. – Frilling

I am unable to reproduce the same problem, but instead, I got a blue foreground. I have a white background, which is correct. But I have blue text for any code formatted in a <span> or a <font>, while I have white text (regardless of background and foreground color from Java code) for text in bare <p>. Note that everything is in the same <p>, white text or blue text, span or font or bare. – Stupefacient

However, background color works in my code. You can find the source code for my project from GitHub (I hadn't got time to simplify the problem). – Stupefacient

Answer 1

As @AndrewThompson noted in the comments JEditorPane is really behind, it supports only a subset of HTML 3.2 and CSS1, and isn't really cable of rendering any modern web pages.

I strongly suggest using an alternative, like:

• JavaFX WebView

  Code Snippet: (no dependencies, you can run it as-is)

  import javafx.application.Platform;
  import javafx.embed.swing.JFXPanel;
  import javafx.scene.Scene;
  import javafx.scene.web.WebEngine;
  import javafx.scene.web.WebView;
  
  import javax.swing.*;
  import java.awt.*;
  
  public class JavaFxBrowser implements Runnable {
      private WebEngine webEngine;
  
      public static void main(String[] args) {
          SwingUtilities.invokeLater(new JavaFxBrowser());
      }
  
      public void loadURL(final String url) {
          Platform.runLater(() -> {
              webEngine.load(url);
          });
      }
  
      @Override
      public void run() {
          // setup UI
          JFrame frame = new JFrame();
          frame.setVisible(true);
          frame.setPreferredSize(new Dimension(1024, 600));
          frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  
          JFXPanel jfxPanel = new JFXPanel();
          frame.getContentPane().add(jfxPanel);
          frame.pack();
  
          Platform.runLater(() -> {
              WebView view = new WebView();
              webEngine = view.getEngine();
  
              jfxPanel.setScene(new Scene(view));
          });
  
          loadURL("http://www.google.com");
      }
  }

  Code Sample:

  XHTMLPanel panel = new XHTMLPanel();
  panel.setDocument("http://www.google.com");
  

  @see BrowsePanel.java

• or NativeSwing

  Code Snippet:

  final JWebBrowser webBrowser = new JWebBrowser();
  webBrowser.navigate("http://www.google.com");
  

  @see SimpleWebBrowserExample.java

Answer 2

A possible reason is that HTMLDocument parses three-digit color codes differently from normal. Hence, everything is shown as blue because only the blue byte (and the lowest 4 bits of the green byte) is set.

For example: #FFF would be interpreted as #000FFF, which is sharp blue.

At least this solved my problem mentioned in the comments. A possible reason for related threads on the background, too.

Answer 3

It seems you have extended JFrame in your class. So please use editorPane Object for setting the color as below

String url="http://google.com";    
editorPane.setEditable(false);
editorPane.setBackground(Color.WHITE);
    try {
        editorPane.setPage(url);
    } ca

I once tried using JEditorPane circa JDK1.3 and the support was awfully limited. From what i understand there has not been much advancements in that API to provide support for browsing.

I recommend you checkout DJ here. Simple to setup and use reliably.
