4-State Button
Hey! A working Example!
Creating sophisticated buttons with
"rollover" and "on-click" effects is an absolute
dream in Fireworks4. You can use the full range of image editing
tools available through the toolbar to create your ideal button
"on-the-fly" inside the button editor, or even use an
existing graphic saved on your hard drive. Literally ANYTHING can
be turned into a button - let your imagination run wild (or use
an image created from following one of my "button tutorials"!).
Obviously, you can only create single "stand-alone" buttons
using the Button Editor, but once it's done, creating a "nav-bar"
is a simple matter of copying/pasting the required number of buttons
onto a canvas or "interface" (but that's a whole other
tutorial!). So, let's get buttoning!
Creating your button
We'll start with a blank canvas, so:
Open a new file, 100x100pixels, white
canvas
Click INSERT>NEW BUTTON. The Button
Editor opens up, with 5 labelled "tabs" showing the 4
possible "button states" (i.e. UP, OVER, DOWN, OVER WHILE
DOWN) and ACTIVE AREA (these states will be explained as we go through
the tutorial).
"UP" STATE 
The UP state of your button is simply
what it will look like while it is sitting on your page, waiting
for some form of user interaction (like mouse rolling over or clicking).
So, put your artistic skills to good use and create your basic button!
(See Basic Buttons Tutorial
if you need a refresher on how to do this!). When you are happy
with your creation, it's time to move on to the next stage by clicking
the OVER tab.
"OVER" STATE 
As the name suggests, the OVER state
is what your button will look like when the mouse cursor passes
over it. On clicking the OVER state tab, you are presented with
a blank canvas. Don't worry - you don't have to recreate the whole
thing! Simply click on the
button at the bottom right of the canvas and SHAZZAM! Your creation
pops up on the canvas, ready to be edited. Feel free to now edit
the fill colour, the text colour, apply a GLOW effect (EFFECTS>SHADOW
AND GLOW>GLOW), whatever takes your fancy! When done, move on
to the next stage by clicking the DOWN tab.
"DOWN" STATE 
O.K., so you can probably guess what
this one means? You got it - once clicked, this is what your button
will look like on the page. So, as before, click on the
button to bring your button onto the canvas and apply whatever changes
to the effects/fills or text you consider appropriate for this state.
It may be that you want to apply different fill colours, or even
to apply a subtle INSET EMBOSS effect (EFFECTS>EMBOSS>INSET
EMBOSS) to make the button actually look "pushed in".
Try not to get too carried away with yourself! Then, click the OVER
WHILE DOWN tab.
"OVER WHILE DOWN" STATE

Here's one I don't normally bother
using (you don't HAVE to use all button states!), but it's there,
so let's use it! The OVER WHILE DOWN state is ... Yep! What you
see if you mouse over a button which has already been clicked! Click
on the
button and off we go! Apply whatever new effects you wish to occur
to the effects/fills or text when the viewer mouses over a button
which is already in it's DOWN state. And, generally speaking, you're
done! Except for the ACTIVE AREA tab.
"ACTIVE AREA"
Once you have created your beautiful
button, with it's many magnificent rollover states, the only thing
left to consider is the ACTIVE AREA. In a nutshell, the active area
defines just how close to your button the mouse cursor has to be
to trigger the rollover/click events. By default, Fireworks will
automatically create a "slice" for the button which includes
the full extent of any effects/text you applied to the graphic (worth
taking note of this, if you have applied any GLOW effects, as the
Glow obviously extends BEYOND the edges of the graphic you see in
the UP state!). You can, of course, tell it to do otherwise by de-selecting
that option.
Although, I have yet to find a good reason for doing that!

If you wish to extend/shrink the active
area, you can do so by dragging on the blue handles at the corners
of the slice, but beware! This may seriously affect the performance
of your beautifully crafted rollover states, or may even affect
the performance of nearby buttons etc. on the same page! More on
this topic in my Basic
Navbar tutorial.
You're now ready to Rock 'n Roll!
You can "demo" your button by using the Play buttons
at the bottom left of the Editor window, or simply close the Editor
(Click the "X", dummy!) and your button will be inserted
into the canvas ready for Saving/Exporting. Have fun!
