7. Check Radio button if you want to link all the buttons (on a given page)
that have this option checked, so that only one of them at a time can be
down.
If you use this technique, make sure all rollover graphics you want to link
have the option checked. Although it doesn't matter how the buttons are
distributed on the page, typically they'll constitute a visible unit like a
navigation bar. Any buttons with the option unchecked are independent.
8. Click OK. The first time you define a rollover state, you'll see rollover
layers established in the document (see below).
WebPlus displays the image assigned to the Normal state. It's a good idea to
preview the page and test each rollover object, then return to WebPlus and
revise as needed. When you preview or publish the Web site, WebPlus takes
care of exporting one image file for each rollover state, and the HTML file for
the published page incorporates the JavaScript code for the rollover event
trapping.
To revise a rollover graphic:
1. Right-click the graphic and choose Edit Rollover....
2. Make new selections as needed and click OK.
Creating variant source images
For each object with at least one activated rollover state, you'll need to provide
a source image. It's the often subtle differences between the Normal image and
the "variants" that make the object appear to switch from one state to another.
For example, if you've checked the "Over" state for an object, you need to
include a variant image that the Web page can display when the button is
moused over. In the following example, two variants of a Home button are
shown—one showing the button highlighted (on mouse over), and a second
image in its default Normal state.
You'll need to create these source images in a separate image-editing program.
