Adding rollovers
The term rollover refers to an interaction between a mouse and a screen
object. For example, you can point your mouse at a graphic (such as a
navigation bar button) on a Web page, and see it instantly change colour or
become a different picture. When you point to a Web page object, your mouse
pointer physically enters the screen region occupied by the object. This
triggers an event called a "mouseover" and, if the underlying code is there to
"trap" this event, it can trigger some other event—such as swapping another
image into the same location. An object whose appearance changes through
image-swapping in response to mouse events is called a rollover graphic.
As a prerequisite to creating a rollover graphic in WebPlus, you'll need to
prepare a picture for each distinct rollover state, using a separate graphics
program. The necessary event-trapping code is generated for you
automatically. WebPlus also lets you directly import rollover graphics created
in Serif DrawPlus (see below).
Rollover options
Adding rollovers is basically a matter of deciding which rollover state(s) you'll
want to define for a layered graphic, then specifying an image for each state.
WebPlus provides four basic choices:
