Operation Manual

154 | Hyperlinks and Interactivity
• Down+Over (only available if Down is activated) implies a mouseover
that occurs when the graphic is already Down, i.e. after it's been clicked.
If you don't activate Down+Over, then the button just stays in its Down
state after a mousedown event, which can cause unresponsiveness (see the
above Note). For a more responsive button, set the Normal and Down
states to graphic A, and the Over and Down+Over states to graphic B. In
this case the Down state effectively means "Down+Not Over" and the
button will revert to its Normal appearance if the user moves the mouse
outside the button, even after a mousedown. It sounds complex, but it
works!
You'll also have the option of specifying 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
at a time can be down.
To create a rollover graphic:
1. In a suitable image-editing program, create the variant source images for
each state you'll be defining. (See Creating variant source images on p.
155.)
2. Click the
Insert Rollover button on the Web Objects toolbar's Insert
flyout.
OR
Choose Web Object from the Insert menu and select Rollover... from the
submenu.
3. Specify which rollover states (see above) you want to activate for each
graphic by checking boxes in the Rollover Graphic dialog. For each one,
use the Browse button to locate the corresponding source image and
specify Export Options for that image (see Setting picture export
options on p.
129).
4. Check Embed files in site if you want to incorporate the image(s) in the
WebPlus file. (For details, see Embedding vs. linking on p.
129).
5. Check either Normal or Down as the button's initial rollover state.
For example, common sense dictates that on a site's actual Home page
you should initially show the "Home" button itself as down, and/or
unresponsive to mouse actions—after all, the viewer is already on that
page—whereas buttons that link to other pages should be in their normal
"up" state and responsive.
6. Click Set... to define a hyperlink target for the button. (For details, see
Adding hyperlinks and anchors on p.
149).
