Operation Manual

62 Working with Hyperlinks and Interactivity
WebPlus lets you add rollover graphics to your Web publications; the
necessary event-trapping code is generated for you automatically.
Adding rollovers is basically a matter of deciding which rollover
state(s) you’ll want to define for a particular object (Normal, Over,
Down, and/or Down+Over), then specifying an image for each state.
For details, consult online help.
About HTML and Java
HTML, of course, is the language “behind” basic Web pages—the
actual descriptive code that tells a browser what to display and where to
display it. While WebPlus doesn’t support full-fledged HTML editing,
it does allow you to add extra HTML code to a page. Using this
approach, you can include HTML and JavaScript fragments generated
by another application, copied from another Web page, or perhaps that
you’ve written yourself.
To insert HTML, choose Web Object... from the Insert menu and
select HTML... from the submenu. Then use the dialog to enter the
HTML code. WebPlus inserts a marker into your publication at the site
where the code will run. Since you won’t be able to see the effect of the
HTML until you preview the exported site, be careful to position the
marker correctly. You’ll definitely want to check your Web page in a
browser! (Tip: You can store HTML code fragments in the Portfolio.)
Java is a cross-platform, object-oriented programming language used
to create mini-applications called applets that can be attached to Web
pages and that run when the page is viewed in a Web browser.
WebPlus lets you add Java applets to your Web publications. You don’t
have to write your own! Plenty of applets are available online—for
example animation, interface components, live information updating,
two-way interaction, graphics rendering, live updating, streaming audio
and video, games, and many more.
To insert a Java applet, choose Web Object... from the Insert menu
and select Java Applet... from the submenu. In the dialog, list the
applet’s component files as well as any necessary parameters (as
described in the applet’s documentation) that specify exactly how the
applet should run. You don’t necessarily need to understand the
underlying code, but it’s essential to make sense of any “Read Me”
documentation that comes with the applet.
