MarvinSpace

The traditional way to put the MarvinSpace applet to a web page is by writing the following text in the HTML:

    <applet codebase="../../.."
        code="chemaxon/marvin/applet/MSpaceApplet" name="MSpaceApplet" width=400 height=400
        archive="mspace.jar,jmarvin.jar,jogl.jar">
    <param name="progressbar" value="true">
    <param name="selectionpanel" value="false">
    <param name="molecule" value="http://www.chemaxon.com/marvinspace/data/1ETS.mol">
    </applet>
    

Let's go through the special elements:

• The CODEBASE option specifies the directory of the Marvin binaries relative to the HTML file. This HTML file is in a subdirectory of the Marvin binaries directory, that's why we use "../../.." here.
• The ARCHIVE option is needed to speed up the downloads. The program code is packaged into compressed JAR files, jmarvin.jar, mspace.jar and jogl.jar.
• To indicate the loading the applet progressbar can be used.
• The applet parameter selectionpanel is used to embed a simple MarvinSpace applet without special GUI elements. However they can also be displayed, this will be discussed in another example.
• The molecule applet parameter is an easy way to load molecule(s) by giving a location of the input or a SMILES string.

To correctly work with Sun's Java Plugin, marvin.js provides platform dependent solutions. Apart from the standard <applet> tag, it uses <embed> for Firefox (mozilla) and <object> for Microsoft Internet Explorer. The applet can be embedded in HTML pages using marvin.js the following way:

<script type="text/javascript" SRC="../../../marvin.js"></script>
<script type="text/javascript">
<!--
mspace_name="MSpaceApplet"; // naming the applet to allow JavaScript calls
mspace_begin(mspace_name,"../../..", 400, 400); // arguments: NAME, CODEBASE, WIDTH, HEIGHT
mspace_param("progressbar","true");
mspace_param("selectionpanel","false");
mspace_param("molecule","http://www.chemaxon.com/marvinspace/data/1ETS.mol");
msspace_end();
//-->
</script>
