Click the slice that you want to use to trigger the image swap in Java

Encode Code 128B in Java Click the slice that you want to use to trigger the image swap

by clicking its representation (in the box on the right) When you click in either box, both boxes update to show your selection

rollover should trigger The drop-down list shows all the frames in your PNG file You can also select the Image File radio button and navigate to an existing image file outside your PNG to swap in Be aware, though, that for the rollover to work correctly in all browsers, the default target image and swapped target image must be the same height and width

Figure 7-5: The Swap Image dialog box allows you to choose the swapped image by name or position on the page

boxes selected Preloading the swapped image ensures there won t be a delay the first time the user rolls over the button that triggers the swap The trade-off is that the Web page takes longer to load initially Restoring the image to default prevents the swapped image from sticking If you want the swapped image to remain in place until the user rolls over another button, deselect the Restore Image onMouseOut check box

A line on the canvas from the center of the trigger slice to the target slice shows that one slice triggers a behavior in the other, as shown in Figure 7-6

You can have multiple buttons trigger a rollover in the same slice, and you can have a single button trigger rollovers in multiple slices Of course, the more big rollovers you have on the page, the longer the page takes to load On the other hand, rollovers provide useful feedback (and instant gratification) to the user, and Fireworks makes producing them a snap

Pop-up menus are a great way to cram a lot of navigation into a small space because they only appear when a user rolls over a button or hotspot Fireworks allows you to specify many of the parameters of the menus appearance To start with, you can choose whether the links in your pop-up menus are made of text or images In a nutshell, that choice boils down to this: Linked text: This option ensures faster download but less control over the appearance of the text, because the text is HMTL Linked images: This option makes for a slower download but gives you more control over the appearance of the text, because the text is graphic You can also customize the position of the menu relative to the slice that triggers it, the color of the text and cell background for both normal and rollover states, and more In fact, there are so many options, we can t cover them all here! After you ve got the basics, though, you ll be poised to explore all the options, if you so desire To make a basic one-level pop-up menu with linked text, follow these steps:

necessary, open the Layers panel by pressing F2 and/or expand the panel by clicking the panel name)

If you have any existing links already on your page, they appear in a drop-down list in the Link column

6 If you want the link to open in a new window or different frameset,

tab over to or click in the Target column to set the target for the link If you simply want the linked page to open in the user s current browser window, leave this column blank, as shown in Figure 7-7 For information on other Target options, see the discussion of links in Book II, 2, or the discussion of framesets in Book II, 6

You can add rows to the list of menu items by clicking the Add Menu button (the plus sign at the top left), or by pressing the Tab key until a text field appears in the Text column
