Introduction into HotNav Applet

This applet realizes a hierarchical navigator for accessing pages arranged as nodes in a tree structure. By clicking on the node labels, pages can be loaded in a target window, directory nodes can be opened to show nodes arranged below or JavaScript commands can be executed. The applet can be configured very flexible using a text file. Icons can be added such that it looks like a file explorer. The size of the tree is not limited. Scrolling is enabled automatically.

The following example shows how to call this applet:

<APPLET CODE=HotNav.class NAME="example" HEIGHT="400WIDTH="120" MAYSCRIPT>
   <PARAM NAME="configfile" VALUE="example.cfg">
   <PARAM NAME="host" VALUE="134.147.58.109">
   </APPLET>

The number of applet parameters on the HTML page is very low. Only the specification of HEIGHT, WIDTH and configfile and optional host are necessary. The main specifications are contained in the configfile, which is a plain text file located in the document directory. If applet methods are used to reference the applet , it is recommended, that the applet is given a name by the NAME parameter. The keyword MAYSCRIPT is only necessary if JavaScript statements will be executed by HotNav.

The value of the optional parameter host should be inserted by the server. It is the IP address of the user computer. This parameter is only necessary when the filter parameter for nodes is used.
