Re: Using JavaScript to Customize Mouse Pointer Graphic??

P: n/a
Prisoner at War meinte:
However, the really odd thing is that you cannot use a "fall-back"
like

style="cursor: url(relative/path/file.ani); cursor:pointer;"
(a) This has nothing to do with JS.
(b) This is not a fallback. You just overwrite your custom-pointer
property with the standard one. In your case you will *always* get a
cursor: pointer.
as is recommended, in case the browser didn't understand...well,
nothing worked in MSIE 7 until I had *removed* that "fall-back,"
"cursor:pointer"!
Small wonder...
style="cursor: url(relative/path/file.ani); cursor:pointer;"

doesn't work, even in MSIE 7, but

style="cursor: url(relative/path/file.ani);"
does!

So, the custom pointer can only show up in MSIE 7, but only if the
"fall-back" hand pointer used by Opera and Firefox isn't present --
else MSIE 7 "prefers" it and uses it, instead of the custom pointer!!
How about
(a) obtaining some *basic* knoledge of css
(b) post into newsgroups dealing with those issues

x'post and f'up set

True -- but having asked on comp.lang.javascript about using
JavaScript, it's the answer I got. I now realize -- in less than a
day of research! -- that it's CSS, but I appreciate the answer all the
same.
(b) This is not a fallback.
So what's a fall-back, then?
You just overwrite your custom-pointer
property with the standard one. In your case you will *always* get a

I thought I was simply following the instructions on something like
http://www.quirksmode.org/css/cursor.html....

Actually, it's a real puzzle how MSIE 7 is more W3C-compliant over
this little thing than Opera and even Firefox!

I've got enough to customize existing CSS files for my own needs.
That seems "basic" enough to me.

Moreover, I just don't think a newsgroup should be an invitation-only
symposium. This is the information superhighway -- new drivers get on
the road all the time.
(b) post into newsgroups dealing with those issues
I have been, actually, even if unbeknownst to you.

Eh? How to get that? Firefox does support 'hand'. 'hand' is a MS
invention. IE7 does not support 'url' or other graphic formats which is
part of the W3 recommendation. If graphic is use FF for does require a
generic fallback but this too is in keeping with the recommendation:
"The user agent retrieves the cursor from the resource designated by the
URI. If the user agent cannot handle the first cursor of a list of
cursors, it should attempt to handle the second, etc. If the user agent
cannot handle any user-defined cursor, *it must use the generic cursor
at the end of the list.*"

IE7 should support 'url'; the question is the format of the graphic
file that represents the custom cursor.

I think this is the best rule of thumb in practice indeed:

cursor: url('cursor.cur'), url('cursor.ani'),
url('cursor.png'), url('cursor.svg'), auto;

In conjunction with a great image converter like:

A strange remark from W3:

I couldn't get PNG01 to work at least on MSIE. But then, even their
own demo on MSDN doesn't seem to work here (Vista MSIE 7.0.6., second
button '#2'):

Indeed it does; I've been able to confirm that.

Yup -- that's the one! Opera 9 won't see any URI, but FF and MSIE can
have their pick of which file format to load!

How about GIMP?? Looks really powerful...it may be all I'll ever
need! I wonder if it does cursors (.ani, .cur), though...any 100%
free cursor creation programs you know of -- without spy/malware??

Well! Is that true??

And what's PNG01?? Is that also .png or does it end .png01??

LOL, yeah, Martin Honnen had referenced that, I think, and I'd also
noted that Button #2 doesn't work!

GIMP might be okay too, but I'm a bit afraid of cursors, and in
particular the favoured Windows formats.

I have been using IrfanView for many years. It has been certified by
www.download.com as "Tested spyware free"; you may want to check the
Spyware listings further at wish.

Well! *Is that true??
"True" is a bit relative here :) The PNG-format is heavily promoted by
the W3C; no surprise they mention it here.
And what's PNG01?? *
http://www.google.com/search?q=png
http://en.wikipedia.org/wiki/Portabl...nd_development
http://www.ietf.org/rfc/rfc2083.txt
Is that also .png or does it end .png01??
png.

Actually, verdana and arial look extremely similar.
No, you are missing the point, noting to do with Arial or Verdana but
the CSS rule syntax.

..correct { font-family: foo, bar; }
..wrong {font-family: foo; font-family: bar; }

Classes "correct" and "wrong" are *not* equivalent. "correct" rule say
use font "foo" but if foo is not available use "bar". But "wrong" sets
the font to "foo" and then changes it to call out font "bar". With class
"wrong" the font will never be "foo".

>A-ha. So what's the JS issue of your problem?

I was asking about how to use JavaScript to customize mouse pointers.
Turns out the answer I got concerned using CSS, but at the time I did
not know that and so just "ran" with the answer.
Agree, not the place for JS...

Sure, if you compare them one isolated letter at a time.
Also (and mostly), what Jonathan said.
>I could also point out, that you shouldn't quote signatures. But I
suppose one has to be happy, that you're not top-posting.

This is really bizarre -- why not quote signatures??? Very, very
strange rules...I mean, why do people have signatures to their posts
if they don't want their signatures quoted??
Three reasons not to quote signatures:

1) You've already got the attribution lines up at the top, so there's no
need to quote the sig, too.

2) Some people's sigs are rather long. Go look at threads with (a lot of)
posts from Jerry Stuckle in them. He often gets in very long back-and-forth
discussions with users of GoogleGroups, and GG doesn't automatically trim
sigs from replies, and GG users don't know any better, and Jerry's too lazy
(or something) to trim out previous sigs (or other irrelevant content), and
his sparring partners don't do it either. But other sigs, longer and
shorter, are unnecessary for quoting. We waste enough bandwidth already.

3) You're not commenting on the sig (well, except in the very rare case
that you *are*), so it should be trimmed like all of the other points to
which you are not directly replying.

I don't mind if you quote *my* signature, but nobody else (except maybe a
shark or two) will be too happy about it.
