The menu found in this panel for the parent and the child need not be the same. That is, the child can have either the same tree popup menu as that of the par- ent node or any other tree popup menu. This feature fulfils the "Any Node Anywhere" concept whereby different types of node can be added under any given parent node. User-defined properties for a new node can be added, modified or deleted at any time. Through this functionality, it is possible to add the key and the value into the table for the particular node. For example, an alarm node can be added as a network event. The "parent node" would be network events. The tree name might be "Test Node" and the panel name "Test Node". The output from this example is shown in Figure 12.22. When adding a node, user-defined properties can be specified which are added to the database. For example, a user-defined property might be added under the attri- bute FRAME TITLE and with value Frame Title. Any number of user-defined proper- ties can be added. 12.11.5 HTML User Interface The HTML client is a browser client, that is, it runs in Internet browsers.
