cursor:auto - how it defined
rvj
mappings for cursor:auto style
- are they defined in a CSS sheet or hardcoded
The official definition says cursor:auto is determined by the browser
context
- but exactly what defines a distinct context ?
As far as I can see only two types are observable
1. cursor over text resulting in I-beam
2. cursor over anything else resulting in default cursor (arrow)

The official definition is very vague.
The only reason to have such a value at all is to have the behavior
where a cursor is a pointer when not over text and an I-beam cursor
when over text. Anything else can be done in the UA style sheet,
and I think should be.

Thus, what we implement for 'cursor: auto' is exactly the
distinction you give, and nothing else. I think that's what the
spec should have said.

... do you know if anyone has found a workaround that allows a document
script to determine WHICH icon is actually visible? I would like to know
when the cursor is over text.
********************************************************************************************
Presumably in an html environment the tagName would provide a good clue as
it indicates the type of object (<img> <h1> etc ). However some of these
assumptions are not very intuitive such as <body><div>. What Im not sure
about whether it is possible to make similar assumptions for other kinds of
object eg flash, etc
I assume that the cursor:auto style relate to the browser's context menus
in some way - or are context menus complely
independent of the current object
For example if it were possible to determine the context menu type , it
might provide a better clue because there are relatively few context menus
in a document.
********************************************************************************************
.. so one final question ..
is there a scriptable way of determining the context menu type (id)
associated with the current object in a mouseover event ?
PP thanks for any pointers !!

Have you been able to resolve this problem of identifying the actual
cursor shape when getComputedStyle returns 'auto'?
I've tried using a list of known tagNames that would normally show
'text' (e.g. B, PRE, STRONG, CODE), but it's not reliable.
For example, a PRE can include line breaks or empty spaces around the
text it might display, and the cursor is 'default'.
How can we know that there's text underneat the current position?
I couldn't get textvalue or text working.
Laurent.
