How to get an Applet in a table-row to size dynamically

Question

I need to insert an applet into a table-row and get that table-row's height to dynamically resize according to the browser's window size. If I put fixed values for width & height in the td-tag, it shows the applet fine, but I need to be able to resize this according to the client's size capabilities, so using fixed sizes is not the answer.

The snippet below should illustrate where my problem lies:

    </head>

    <body bgcolor="#6f6f6f" >
        <table border="0" cellspacing="0" cellpadding="0" width="100%" >
            <tr valign="top">
                <td><img src="images/myheader.jpg" alt="myheader.jpg"></td>
                <td><img src="images/mylogo.jpg" alt="mylogo.jpg"></td>
            </tr>
            <tr >
                <td colspan="2" >
                    <object codetype="application/java"
                             classid="java:applets.MyTestApplet.class">
                        <param name="codebase" value="." >
                        <param name="archive" value="MyTestApplet.jar" >
                        <param name="code" value="applets.MyTestApplet" >
                    </object>
                </td>
            </tr>
        </table>
    </body>
</html>

What do I need to do to make the row-dimensions dynamic?

[edit] jitter's answer indicates a possible solution. I also need to adjust the relevant sizes when the user resizes the window: what event & how do I do that?

I suggest using javascript to write the object/embed tag and calculating the size dynamically.

This should do the trick basically but be aware of the fact that getting the correct width and size can be tricky. I refer you to Finding the size of the browser window.

...
<head>
...
  <script type="text/javascript">
    window.onresize = function(event) {
      document.getElementById('myobject_tag').height = window.innerHeight;
      document.getElementById('myobject_tag').width = window.innerWidth;
    }
  </script>
</head>
...
<body bgcolor="#6f6f6f">
  <table border="0" cellspacing="0" cellpadding="0" width="100%">
    <tr valign="top">
      <td><img src="images/myheader.jpg" alt="myheader.jpg"></td>
      <td><img src="images/mylogo.jpg" alt="mylogo.jpg"></td>
    </tr>
    <script type="text/javascript">
      var height = window.innerHeight;
      var width = window.innerWidth;
      document.write(
        '<tr><td colspan="2"><object id="myobject_tag"\n' +
        'codetype="application/java"\n' +
        'classid="java:applets.MyTestApplet.class"\n' +
        'width="' + width + '"\n' +
        'height="' + height + '"\n>' +
        '<param name="codebase" value=".">\n' +
        '<param name="archive" value="MyTestApplet.jar">\n' +
        '<param name="code" value="applets.MyTestApplet">\n' +
        '</object></td></tr>'
      );
    </script>
  </table>
...

Thanks, your script works 100% (on firefox). Now I need to just adjust it to make the table fit. — slashmais, Oct 11 '09 at 07:29
Also: I need to adjust the sizes when the user resizes the window. Is there some kind of event I can use & how? ( I'm new to Java/web development - normally do C++, and let no-one tell you it's easy to pickup Java if you know C++, it is not: Java/web-dev is much more diverse/complex.) — slashmais, Oct 11 '09 at 07:42
enhanced code snippet. note javascript in head and the id tag in the object tag — jitter, Oct 11 '09 at 08:06
Thanks - exactly what I needed. (Got the table-size fitting nicely in the meantime) :-) — slashmais, Oct 11 '09 at 08:23
