(R561) Modifying a More Complex Applet

The second applet, "My Wandering Mind-2", is an extension of the first one and introduces a few new features. The applet parameters are of the form Name, or Name1-Name2, or Name1-Name2/n. The single Name parameter represents a single disconnected node, the Name1-Name2 shows that Name1 is linked to Name2, and Name1-Name2/n links the two names but with a replusion factor of strength n.

For example, if we have the string:


   <PARAM NAME=edges VALUE="Dog-Cat/100,Cat-Mouse/200,Mouse-Cheese">

then there is a link from Dog to Cat with a repulsion factor of 100, from Cat to Mouse with a repulsion factor of 200, but an intimate relationship between Mouse and Cheese. Dog is directly linked to Cat, but only indirectly to Mouse and cheese.

An other consideration is that a string of one type of parameters must reside on a single text line. Thus if you have many values in the "PARAM NAME=edges..." string (as my 2nd applet does) you need an editor that can operate on long lines. One such editor is TED which is available on all C&C machines. If you set the right margin to a very large value, e.g., Cmd: RM 2000 , then you can edit my 2nd example.

Try editing my 2nd example, larry-mind2.html , with your own set of nodes and relationships. The only extra thing you have to do is copy it to your existing Java directory:

cp ~larryg/public_html/Java/larry-mind2.html Java

and then edit it and link to it as before. My 2nd applet looks like this:


<TITLE> My Wandering Mind-2 </TITLE>
<H1> My Wandering Mind-2 </h1>
<H1> Hey, I'm a more complicated guy than at first glance.  Here is 
the real me! </H1>
<HR>
<APPLET CODE="Graph.class" WIDTH=600 HEIGHT=400>
<PARAM NAME=edges VALUE="Larry-Food,Larry-MoreFood,...
<PARAM NAME=center VALUE="Larry">
</APPLET>
<HR>

The trailing line "..." indicates that a lot more values fit than can be shown here.

Oh, and one more thing: these examples assume that all of the .class files and the applet HTML are in the same directory. There is another applet parameter named CODEBASE that lets you place the applet and .class files in different directories.
