I need opinions on application design
Hi all,
I'm starting to develop an Java Swing application that will exibit and let
users navigate on territorial maps. A feature of the application is to
exibit icons on specific coordinates of the maps, representing places marks
the users can click to interact with. So, I have a least to "layers": one
for the map and another for this icons. I'm not in the field of graphical
applications design, so my question may be to simplistic or wrong. The
question is: what is the best way to handle the icons on the maps? I see two
options, one being place the icons inside the svg drawing file, maybe as
<symbol>, and positionig them accordingly; and the other being handle all
these icons on the Swing side, painting them on demand over the JSVCanvas to
meet the map showing. What is the best (or correct) approach?
Any other opinion about it?
Thanks,
Charles Abreu

I'd put them in the SVG file via exteral references, e.g.:
<image transform="translate(100, 100)" xlink:href="/icons/foo.jpg"/>
You keep the files separate yet have the ease of SVG placement/rendering.

Thank you, Fennell and Archie! I will follow your recommendations and play a
bit with the code to see how it will go, specially with the user interaction
scenarios. I was only afraid by not knowing the way to start walking.

Charles,
Most definitely put the icons in the SVG, and for that matter, use SVG
for the icons too.
If you keep as much of the map's behaviour within the SVG as possible it
opens the door for delivering the application over the internet to via
browsers like Firefox and Opera (when they have better support for SVG)
and also the Adobe viewer too. All the host application (Java or
additional JavaScript) has to do is register event listeners on the SVG
if it needs to carry-out additional work to respond to user input.

Philip Fennell
