Hi all,

(after diligently searching the archives, finding tidbits here and there,
and still being in the dark), here's my problem.

1. I want to use SDL's mapplet the way it is used in Landview. Click or
click and drag, release the mouse button, and boom... get a fresh map. I
simply can't fathom how to accomplish this. I can click or click and drag to
get the red box, but then I have to press the submit button to submit the
form actually. How do I activate the boolean 'redraw'?

2. How do I enable the swap method? that is, refresh only the image not the
page?

3. How do I enable the pan buttons (and any other buttons, for that matter).
Do I form.submit() onClick?

4. How do I have the results of a query (or nquery) be displayed in a
specific frame? For example, if I want to create a frames application so the
results are displayed in the bottom frame.

I have studied the landview source, but that code is so complicated for me,
a Javascript newbie, that my eyes are swimming. If I can accomplish the
above, I would be happy to put together a doc or even templates that allow
others to accomplish the same easily.

Another question --
 
Landview performance is really, really nice. What's the trick? I am using a
PIII / 800+ MHz with 256 Mb RAM on a Win2k box with Apache 1.3.20; not
great, but not too shabby. But the performance sucks (a few hundred MBs of
shapefiles). Is that not good enough? Is the mapserver more responsive on a
*nix box? What are the specs of the box running landview?


Many thanks in advance.
