Java Swing HTML Editor

Hi,
I am doing a HTML Editor in java.I want to insert a <div> </div> for every new line entered.If I insert a div tag using
new HTMLEditorKit().insertHTML(doc,offset,"<div> </div>",1,0,HTML.Tag.DIV);.
It's inserting two new line characters..
Help!

Hi !
I�m writing an HTML Online Editor! I didn�t tried div yet, but i insert functionality for background, color chooser, links, ......
If you would like, I could put my Applet on my Server and you can take look at it.
It�s for open source, so you could see me actual source too. I also would be very interested in seeing yours.

Help to show a HTML file in Swing

Hiiiiiiiiiii,
During my development Me in a problem . Please help me out.
As per my current context of the project I have to develop a HTML page with Help of CSS and all other things. After that I have to Show the HTML file through Swing. I know how to attach a file with help of URL but need some help to show a HTML file in Swing.
*help to show a HTML file in Swing*

As camickr said Javascript support is not available. If you want to support you have to write code for that. Up to an extent CSS support is provided.
Sample code to display HTML pages in JTexPane (you can use JEditorPane as well):
Construct the URL:
URL url = YourClass.class.getResource("resources/Hello.html");
// If YourClass is in package test.html, then your html page must be available in .....test/html/resources directory.
// And your CSS files must be accessible from your HTML page. This you can test by simply opening the html
// page in your favorite browser.And then call setPage() method of HelpDataPane. Note that, HelpDataPane supports hyperlink activation.
import java.io.IOException;
import java.net.URL;
import javax.swing.JTextPane;
import javax.swing.event.HyperlinkEvent;
import javax.swing.event.HyperlinkListener;
* A pane to display help pages. Help pages are accessed as URL and displayed
* in this pane.
* @author Mrityunjoy Saha
* @version 1.0
public class HelpDataPane extends JTextPane {
     * Creates a new instance of {@code HelpDataPane}.
    public HelpDataPane() {
        super();
        this.addHyperlinkListener(new HyperlinkListener() {
            public void hyperlinkUpdate(HyperlinkEvent e) {
                if (e.getEventType().equals(HyperlinkEvent.EventType.ACTIVATED)) {
                    setPage(e.getURL());
     * Sets the current URL being displayed. The content type of the
     * pane is set, and if the editor kit for the pane is
     * non-{@code null}, then
     * a new default document is created and the URL is read into it.
     * @param page The URL to be displayed.
    @Override
    public void setPage(URL page) {
        try {
            super.setPage(page);
        } catch (IOException ex) {
            try {
                URL blankURL = YourClass.class.getResource("resources/Blank.html");
                super.setPage(blankURL);

Build a xml editor using swing

I would like to know a simple way to build a xml editor using swing. The editor should present the xml in a tree structure, THe user should be able to modify the xml in the editor and save it.

Try reading this from [The XML Tutorial|http://java.sun.com/j2ee/1.4/docs/tutorial/doc/JAXPDOM4.html#wp64247] for discovering how to display the XML tree first, this is the first point to build a XMLNotepad like solution.

HTML Editor

Well, Howard Kistler has certainly already signed with an editor to sell its HTML Editor Applet. So instead of being parasites and begging for code, why not spit in our hands and code it by ourselves ?
I've made some tries yesterday for a HTML editor application. So far, there is an appli where one can edit text, and set it bold or italic with a menu. One can also dump the HTML code to stdout.
Here is the code, it's very simple, and after that I'll have some questions for you.
import javax.swing.*;
import javax.swing.text.*;
import javax.swing.text.html.*;
import java.awt.*;
import java.awt.event.*;
import java.util.*;
public class Bla extends JFrame {
 JEditorPane jep;
 Hashtable actions;
 private Action getActionByName(String name) {
 return (Action)(actions.get(name));
 public Bla() {
 jep = new JEditorPane();
 jep.setContentType ("text/html");
 // shouldn't insert HTML test not done with a JEditorPane
 // jep.setText ("This is a test !!");
 // store and display available actions for this Editor Kit
 actions = new Hashtable();
 Action[] actionsArray = jep.getEditorKit().getActions();
 for (int i = 0; i < actionsArray.length; i++) {
 Action a = actionsArray;
actions.put(a.getValue(Action.NAME), a);
System.out.println (a.getValue(Action.NAME) + " = " + a);
System.out.println ("TEST : " + HTMLEditorKit.BOLD_ACTION); // --> "html-bold-action" !!
// builds menu bar
JMenuBar jmb = new JMenuBar();
setJMenuBar (jmb);
JMenu jm = new JMenu("commands");
jmb.add (jm);
jm.add (getActionByName ("font-bold"));
jm.add (getActionByName ("font-italic"));
JMenuItem out = new JMenuItem("output text");
jm.add (out);
out.addActionListener (new ActionListener() {
public void actionPerformed(ActionEvent e) {
System.out.println ("CONTENT : " + jep.getText ());
// insert editor to a scroller and add all that to our frame
JScrollPane scroller = new JScrollPane();
 JViewport port = scroller.getViewport();
 port.add(jep);
getContentPane().add (scroller, BorderLayout.CENTER);
addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
pack();
setSize (400, 400);
show ();
public static void main (String args[]) {
new Bla();
Questions :
1) When we display HTMLEditorKit.BOLD_ACTION, the result is "html-action-bold" but this action does not exist in the action list that we got from the EditorPane ! Is it a bug or just something I didn't understand ?
2) Is it a comprehensive list of all available actions on an EditorPane ?
3) If you try to set the HTML text by yourself, the Editor won't like it unless it is perfectly structured (usage of , by example). Strange behaviour and bugs will occur if you try it.
4) When the HTML content is sent back, it is enclosed in <html><head></head><body>...</body></html>. What part of the architecure generates this code and how to get rid of it (not by String manipulations, of course).
Thanks for your help. And see you soon for the next version !

Embeded html editor

Hello there:
In my project I wanted to add rich text support for the editor thus I used DefaultStyledDocument. It works fine, as it supports Bold/Italic/underline, foreground/background, etc, and I can save the data as the binary files. However, I was impressed by the online html editor like this: http://www.interspire.com/devedit/
I think Swing should be able to implement something like this. I don't really want my users able to access the html code, I just want my application to provide a WYSIWYG environment and the app is going to save the data as HTML files in the background.
I noticed there is a class extending DefaultStyledDocument, HTMLDocument, I am not sure if this class can help me reach my goal.
Any suggestions? Or link to some sample code?
Thanks a lot,
Sway

Hi Benjamin,
I believe the translator interface being talked about is IJsTranslation.
That may be a good place to start looking. It can be found in
org.eclipse.wst.jsdt.web.core.
The main JSDT specific extension point you'll probably use is:
org.eclipse.wst.jsdt.web.core.javascriptPreProcessor - where you specify
your translator.
Take a look in org.eclipse.wst.jsdt.web.core and
org.eclipse.wst.jsdt.web.ui to see how JSDT support gets added to the HTML
and JSP editors.
Thanks,
Chris

HTML Editor Kit adding extra characters...urgent

I am facing a strange problem in using HTML Editor Kit. I am using JTextPane to display the HTML data, which will support bold, italic and underline formatting.
The problem is, when I
1]Enter some text of length more than 71, with some spaces inside it ( Do not press enter key explicitly).
2] And try to read that data from the editor kit.
I find some new line characters inside the data as shown below in the example.
Example :
=========
I entered "Testing the HTML Editor Kit functionality .. as well as Apply functionality too.. as these are giving some problems. what can be the reason. try to find out that..." in the Editor Pane and Editor Kit is generating the following HTML for it.
<html>
<head>
</head>
<body>

Testing the HTML Editor Kit functionality .. as well as Apply
functionality too.. as these are giving some problems. what can be the
reason. try to find out that...

</body>
</html>
Although I haven't entered any new line between the paragraph tags, still you can find that the editor kit is adding some new line characters and 6 spaces from line to line. One consistency about this behavior is that it enters this stuff after 71 characters only with some special cases.
How can we change this behavior. What all I need is I want the data in a simple string like
"<html><head></head><body>Testing the HTML Editor Kit functionality .. as well as Apply
functionality too.. as these are giving some problems. what can be the reason. try to find out that...
</body></html>"
Any solution???
Thanks
Priyatam

That's strange isn't it? Class HTMLWriter sets the line length for HTML output to 80 chars per line. Strangely JEditorPane seems not to ignore these newline chars although the actual newline is not performed within JEditorPane.
See http://java.sun.com/j2se/1.3/docs/api/javax/swing/text/AbstractWriter.html#setLineLength(int)
about how to set the line length.
Hope that helps
Cheers

Suggest a HTML Editor component

Hi ,
We need a Swing based (ready to use) HTML Editor component to be integrated into our application.Does anyone of this kind component?I have been searching for Swing based HTML Editor component for the last days in vain.Plz suggest any components or atleast tips regarding this.
Thank you
Sunil G

You never know..!! Reveler might visit his question or might have assigned alert to this post.
I have already posted similar question in Swing Forum and still looking forward to get imput.
You seems very agresive in your statements, I would like to understand the concern in detail. What is it that is bothering you. A dead post activated by me? Or you know it for sure that Reveler will never reply.
Thanks,

How to create a WYSIWIG HTML editor

I need to create a WYSIWIG HTML editor and I'm thinking of using Swing.
I realise many have done this before and that there are products already on the market ranging from Coffee Cup to Dreamweaver.
However, this will be for a specific application where my users will need to drop some composite objects on to the web page -- these objects will generate chunks of HTML containing some of my own attributes with a special syntax. These objects might be as simple as a textbox with a label, or something more complex.
So the idea is that the user selects the object they wish to create by clicking a particular icon in a palette. The cursor changes to a cross-hair as the mouse is moved across some sort of canvas pane. The user clicks where they want the top left-hand corner of the object to be (rubber banding not necessary). A dialogue pops up asking for some context-sensitive properties for the object. At this point, the system can work out the HTML object it needs to create, i.e. tags, attributes, etc.
So far the canvas pane has acted as a simple drawing surface, perhaps with a set of grid lines to aid the user in positioning. But at this point, know that we know the HTML object required, I want it to be rendered on the pane as HTML.
Is it possible for a pane to be both a canvas an an HTML renderer like this, so that I can achieve a true WYSIWYG effect ? Does anyone understand what I'm talking about ?! Are there any examples of how I would go about this ?
Thanks

Is it possible for a pane to be both a canvas an an HTML renderer like this, so that I can achieve a true WYSIWYG effect ? Does anyone understand what I'm Check out JEditorPane and JTextPane for HTML support. You have to do JEditorPane.setEditable(false) to make it render html. It also SUCKS as a web container - no support for style sheets, forms, javascript, etc.
It is definitely possible to add components into or over the JEditorPane to show lines and other things. I'm just not sure what the point of this is.

Creating a PHP/HTML Editor

I'm doing a school project on a PHP/HTML Editor.
I'm looking for some help on finding a good tutorial on changing properties to a JEditorPane. I want to set up the indent size, colors for tags, comments, statements, etc...
anyone help??

Here, I stole this code from the advanced forum on Saturday and tried to develop it, though gave up when I couldn't get setTabs or load file to work and tooltips was too damn slow.
I had an idea that I could use it to run javac and to execute Frames and Applets with it ... right now I'm reconfiguring the design and thinking about dropping the highlighter altogether, but thats my story.

Creating a WYSIWYG HTML editor

quick question:
I'm creating an HTML editor using JTextPane for my GUI and an HTMLEditorKit in the back. I'm just running a simple test with the following html file:
<html>
<head>
</head>
<body>
 
 let's make a web page
 
 
 
 
 just to see if this works
 
</body>
</html>I'm calling
HTMLEditorKit editorKit = new HTMLEditorKit();
HTMLDocument doc = (HTMLDocument) editorKit.createDefaultDocument();
editorKit.read(m_reader, this.getDoc(), 0);where m_reader is a FileReader linked to the above file.
Then I'm using that as the content for my JTextPane by saying
textPane = new JTextPane(doc);Then when I do a System.out.print(textPane.getText()), I get:
<html>
<head>
</head>
<body>
 
 
</body>
</html>any ideas?

I'd create my own Draw2D figure to render text boxes and other html
elements. SWT widgets can't (as far as I know) be embedded in the GEF
GrapicalViewer's main (SWT) control. You're building blocks are Draw2D
figures. A nice emulated lightweight solution (c.f swing).
The other great advantage, is that a figure based TextField gives you the
the ability to style the appearance of the textbox, ie border, colour, etc.
You could create a base figure styling interface.
The TextField or TextBox, could be based on a draw2d.text FlowFigure.
You're also going to need to have some form of FlowLayout for the page,
to emulate how elements flow on a HTML page in a browser.
I guess the Logic Diagram labels are a good place to start looking.

Textarea with HTML editor is not working

Hi all,
This is producing me a real headache.
I created the simplest application in the world with one Textarea with HTML editor, and the editor control does not show the usual tool bar for fonts, color, alignment, etc. Just a ordinary textarea.
Moreover, this was working before... I moved to another location in my work (me, not the server). Yes, I thought about the Internet Explorer, but Firefox has the same issue.
So any idea I can try to make this work?
I have another applications already in production with the same issue.
Need help!!!!!!!!!
Thanks in advance.
Lukas.
Application Express 2.1.0.00.39
Oracle Database 10g Express Edition Release 10.2.0.1.0
Internet Explorer 7.0.5730.11

Windows XP Service Pack 2

Lukas,
I would go and integrate FCKEDITOR (http://www.fckeditor.net/ ) into your application.
Here are instructions on how to achieve this (sorry but only in German):
http://www.oracle.com/global/de/community/tipps/einbinden_fckeditor/index.html
It basically means:
1) copying the files from fckeditor under the /images directory
(you can use the instructions here: http://daust.blogspot.com/2006/03/where-are-images-of-application.html)
2) creating two shortcuts INCLUDE_EDITOR_SCRIPTS and EDITOR
3) placing the shortcut INCLUDE_EDITOR_SCRIPTS into the page html header and
4) placing the shortcut EDITOR into the post element text of your plain textarea element
That's it.
BTW, FCKEDITOR has been included in Apex 3.0 as a standard item type.

~Dietmar.

Creating a small HTML-Editor using JEditorPane

Hello! I'm trying to create a small HTML-Editor. Via this editor users shall be capable to create formatted text (bold, italic, underlined, different sizes, different fonts, different colors). Furthermore, if the user pushes the enter-button a new line-break ( ) shall be inserted. Basically my editor is working but with some big problems:
1. When I create an instance of my editor, I initialize it with some html-code.
this.m_EditorPane.setText("<html><head></head><body></body></html>"); Without this initialization between the <body> and </body> and will be inserted, what I don't want. But if I push now the enter-button at the beginning, -tag will not be inserted in the <body>-area but in the <head>-area.
2. Styling text is working really good, but when I insert a line-break (via enter-button), the -tag is inserted after the (e.g.) closing bold-tag (). So, in the next line, this style-property must be reselected.
Can anybody help me to change this behavior?
Kind regards, Stefan
P.S. The way I insert the -tag:
JEditorPane editor = getEditor(ae);
HTMLDocument doc = getHTMLDocument(editor);
HTMLEditorKit kit = getHTMLEditorKit(editor);
editor.replaceSelection("");
int offset = editor.getCaretPosition();
kit.insertHTML(doc, offset, " ", 0, 0, HTML.Tag.BR);
editor.getCaret().setDot(editor.getCaretPosition());P.P.S. Sorry for my bad english :-/

Who can help me with replacing the standard HTML editor in WPC?

Hi all,
We have chosen to replace the standard HTML Editor in the Web Page Composer by the TinyMCE Editor. I have worked my way through the document written by Boris Magocsi (https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/f04b5c5d-3fd2-2a10-8ab0-8fa90e3ac162) and the TinyMCE Editor is diplayed when we add or edit a paragraph.
However, we can not type any text in the input field anymore and we can not click any of the buttons in the TinyMCE editor. Can anybody help a total Javascript newby with fixing this? Full points will be awarded obviuosly. Thanks in advance!
Best regards,
Jan
Note: We are on NW 7.0 SP 15 and the WPC component is not patched yet. We are trying to complete that today and patch it to patch level 1.

Run script in HTML editor in WebView WP8.1

I am developing an app in which I need to give HTML editing facility to the user. So I tried different HTML editors but finally TinyMCE was able to show controls for editing. But I am not able to set the contents of Editor. It gives Exception Exception
from HRESULT: 0x80020101. And I tried all different solutions but could not figure it out. Here is link to my project
string tinyMice = "<script type='text/javascript'> function myfun() {tinymce.execCommand('mceInsertContent', false, getQueryStrings());}myfun()</script>";
await System.Threading.Tasks.Task.Delay(TimeSpan.FromSeconds(1));
await webview_demo.InvokeScriptAsync("eval", new string[] { tinyMice });
Can somebody help?

hey,
I am not sure what you exactly want to do but I took a look at the project you uploaded.
First of all, you better use the NavigationCompleted or
FrameNavigationCompleted event for executing onload functions.
I have no idea about the tinymce js plugin but here is what I did to create a similar scenario.
1) First, create a js function in the removeformat.html to return a string (replacing your getQueryStrings functions)
function returnMessageValue() {
return "Hello JS World";
2) then create a script notify event handler and wire it up to the page so we can get alerts from the html page loaded.
In NavigationCompleted event:
string result = await this.webview_demo.InvokeScriptAsync("eval", new string[] { "window.alert = function (AlertMessage) {window.external.notify(AlertMessage)}" });
this will notify the webview about window.alert's. So we subscribe to the Script notify event:
webview_demo.ScriptNotify += (sender, args) =>
MessageDialog m = new MessageDialog(args.Value);
m.ShowAsync();
and finally the code execution for our function:
await webview_demo.InvokeScriptAsync("eval", new[] { "window.alert(returnMessageValue())" });
// await webview_demo.InvokeScriptAsync("eval",
// new[] { "tinymce.execCommand(\"mceInsertContent\", false, getQueryStrings())" });
result:
hope it helps
