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 on a web page, and see it

instantly change color or become a different picture. In more detail, 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"

which 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—the state of the graphic

changes in response to screen events.

You can directly import rollover graphics created in Serif DrawPlus. (See online

Help for more information.)

Rollover options

Adding rollovers is basically a matter of deciding which rollover state(s) you'll

want to define for a particular object, then specifying an image for each state.

WebPlus provides several choices:

Normal State

is the "resting" state

of the graphic before

any rollover, and is

always defined.

Over State

is the state triggered

by a mouseover—

when the mouse

pointer is directly over

the graphic.

Down State

is triggered by a

mouse click on the

graphic.

Another state, Down+Over (not illustrated) implies a mouseover that occurs

when the graphic is already Down, i.e. after it's been clicked.

You can also specify a hyperlink event—for example, a jump to a targeted web

page—that will trigger if the user clicks on the object. And you can even group

buttons on a page so they work together—and only one button in the group can

be 'down' at any one time.
