How to use HTML in JavaFX controls?

Does JavaFX support using HTML in JavaFX controls' text? For example, in Swing components:
button = new JButton("<html><font face=arial size=16><center><b><u>E</u>nable</b></font><br>"
  + "<font face=cambria size=12 color=#ffffdd>middle button</font></html>");
If no, could we find a workaround?

Embedding a WebView in a Labeled for HTML Rendering
A WebView is a node which displays HTML.
Most controls implement Labeled, or have elements that are Labeled.
A Labeled has a setGraphic(node) method which allows you to set the graphic attached to the labeled to any given node (including a WebView).
For instance:
WebView webview = new WebView();
webview.getEngine().loadContent("<html><font face=arial size=16><center><b><u>E</u>nable</b></font><br><font face=cambria size=12 color=#ffffdd>middle button</font></html>");
webview.setPrefSize(150, 50);
Button buttonWithHTML = new Button("", webview);
should create a button with html in it (I didn't actually try running the above example).
Apart from the relatively slow startup time on first use and the overhead (which I can't quantify) of using WebView in this way, there are a couple of jira requests outstanding which make it a little bit of a nuisance.
RT-25004 Allow for transparent backgrounds in WebView
RT-25005 Automatic preferred sizing for WebView
You can vote for the above jira requests or comment on them if such functionality is important to you.
TextFlow/FXML/CSS Alternative
Rather than using html in the Labeled, support for the TextFlow control was introduced in Java 8, so that could be used instead.
TextFlow also works well with FXML and css if you prefer to have the stuff in the TextFlow managed via markup and a declarative styling language.
Open Feature Request
There is an open feature request RT-2160 HTML support for text which is currently scheduled for implementation in the initial Java 8 release.  I think the likelihood of it actually being included there is zero percent, though it may be considered for a future release.  You can vote for the issue or add comments to it, or provide an implementation if you are so inclined.
Implementation Considerations
A possible implementation would be something which parses the HTML then constructs a TextFlow the parsed HTML according to processing rules which are laid out in laborious mind-numbing detail in the HTML5 spec.
You could use a relaxed HTML parser such as the validator.nu parser (though there may be others which would be a better fit). 
A simple implementation would just be to use the parser in the jdk which is used for the swing controls, but that is hopelessly outdated.
Perhaps, even simpler would to only accept strict html input and just use SAX to parse it out, though things like validator.nu are too difficult to work with.
Then, for the limited number of parsed tags that you want to support (and you really don't want to support all of HTML5 for something like this - otherwise you would just use WebView), create your TextFlow from the DOM model that your parser has created.
I wouldn't even both trying to handle most of the stuff in your html string in your implementation, stuff to do with styling, fonts, colors, etc. Those things were never any good in html anyway, and css is better for handling them, so just support stuff commonly used in usual modern day html (take a look at bootstrap html source as an example to see what that might be - if bootstrap doesn't use it, I don't think you should support it).  The stuff you will be supporting are things around document structure like lists, headings, etc. div blocks and span nodes - so only implement that important stuff and delegate everything else to css where it belongs.
Also make sure your implementation fits in with FXML so that you can easily embed your html subset in an FXML doc.

  • How to use HTML Video for iPad in iWeb

    I agree with all the advantages of HTML Video. How do you use html video on your iweb site?
    I want my iWeb site video to be viewable on iPads.
    I have learned the technique to use the HTML Snippet tool in iWeb to successfully post Flash video. I created all of my animations using Kenote's keyframe ability and have exported them to Quicktime and then have converted them into flash with Vertical Moon's Video to SWF. Then simply upload the SWF file to a folder on your idisk, then use the Flash Video insert HTML Snippet and insert the idisk url of the SWF file and you are done. What is the technique for HTML Video?
    I have found some HTML video encoders, here are the links:
    http://www.projekktor.com/ the technique is not clear to me and appears complicated.
    http://www.brightcove.com/en/ this one is way too expensive at $99 a month.
    http://jilion.com/sublime/video this one looks great but is not yet available and I am guessing it is a converter that will make your iMovie Quicktime into HTML Video.
    I have all of the i-Apps and Final Cut Express (2 revs out of date). Can I get the proper HTML video file from these programs, unless I am missing something I don't think so.
    Most people do not believe I made my site completely with Keynote and iWeb but here it is. http//www.falcon-pacific.com
    Thank You Very Much for considering my question. I will put the results on my iWeb site and the exact procedure and acknowledge all the sources of the solution.

    I want my iWeb site video to be viewable on iPads.
    Your videos ARE viewable on a iPad. No need for explicit HTML video coding.
    If you export your movies to iPhone that's all there is to do. You can do it in QT Pro/iMovie
    And HTML Video is a HTML code, not the movie itself :
    <video width="480" height="270" src="movie.m4v" controls></video>
    I use the iPad simulator in the SDK :

  • How to use HTML or XML described visual forms for data entry in Java app?

    Hi,
    We are considering to use HTML as a mean of configuration for visual content and layout of data entry dialogs in our Java GUI applications. Java program will need to be able to populate/collect data into/from dialog controls. I am guessing that JEditorPane and FormView classes could be used for this but I have not figured out yet how to do this.
    I would really appreciate any help you could provide with respect to this. Please share any tips, utilities, references, etc. Maybe one can suggest non-HTML (e.g. XML, UIML, ...) way to achieve the same requirements and recommend some utilities respectively.
    Thanks.

    Just to clarify, we need a solution for Java application (no applet, no web server, no servlets, no JSPs, no EJBs).

    Hello,
    You can embed the verbatim elements in your datatable, ie,
    <h:dataTable value="#{menuItem.breadCrumb}" var="bread" >
      <h:column>
        <f:verbatim><li></f:verbatim>
        <h:outputLink id="crumbID" value="#{bread.menuLink}">
          <h:outputText id="crumpName" value="#{bread.menuLabel}" style="width: 165px;"/>
        </h:outputLink>
        <f:verbatim></li></f:verbatim>
      </h:column>
    </h:dataTable>

  • How to use HTML parameters in Java applet

    Hello
    In perl I have created a form with things like a selectiuon box called currency and text fields called product for example. Then when I click submit the perl program can pick up the currency and product parameters.
    I have read about applet param eg <param name="param1" value="Apple"> is this the same thing? Or is it different?
    Can I use HTML parameters or do I need to use applet param? I am confused.
    If applet param is what I need, then how do I change the param values say by editing text in a text field?

  • How to use html tags inside java

    I have to retrieve data from db and return the data to my index.jsp page.
    Its working fine.
    But I have o display in a pable format using html. How to embed html tags? I tried this way. Its not working. Any suggestions?
       String htmlOpen = "<html>";
        String htmlEnd = "</html>";
        String titleOpen ="<title>";
        String titleEnd ="</title>";
        String bodyOpen = "<body>";
        String bodyEnd = "</body>";
        for (int i = 1; i <= cols;i++){
            output = output + rsmd.getColumnName(i);
         while (rst.next()) {
            for (int i = 1; i <= cols;i++){
                      output = output +rst.getString(i);
      result = htmlOpen + titleOpen + titleEnd + bodyOpen + output+ bodyEnd + htmlEnd;
        stmt.close();
        conn.close();
         return htmlOpen;
      }

    See those charcters in your JSP that look like "<%"? Those characters mean: "the code after this is Java - interpret it as such".
    Then when you close your Java block with "%>", it then means: "the code after this is html - output it to the request response that is being built. However, within the html code, the syntax "<%= java_variable_name %>" means "take the current value of that Java variable and insert it into the html output".
    Here's an example:
    %>
    <table cellspacing="2" cellpadding="2" border="1">
    <tr>
    <%
        String s = null;
        for (int i = 1; i <= ncol; i++)
          s = rsmd.getColumnName(i);
    %>
      <th nowrap><A HREF="<%=sortLink.toString()%>&sortby=<%=s%>"><%= s %></th>
    <%
    %>
    </tr>
    <%
        if (rs == null || numRows <= 0)
          %><tr><td colspan="10" nowrap>No data available for specified query.</td></td><%
        else
          int rowCounter = 0;
          while(rs.next() && rowCounter < PAGE_SIZE)
            rowCounter++;
    %>
      <tr><%
            for (int i = 1; i <= ncol; i++)
              s = rs.getString(i);
              if (rsmd.getColumnName(i).equalsIgnoreCase("password"))
                    %><td nowrap>********</td>
    <%
              else
                %><td nowrap><%= s %></td>
    <%
            %></tr><%
    %>
    </table>This is JSP 101, what they teach in the first hour of class...

    thx

    to preserve encapsulation you can use the public-init modifier like so
    public-init var foo;This allows initialization from public and read from public but write only from within the same script (file).
    All of the access modifiers are explained here: [http://java.sun.com/javafx/1/tutorials/core/modifiers/|http://java.sun.com/javafx/1/tutorials/core/modifiers/]
