Second, is it possible for me to detect that the mouse is over a
link and change the cursor to something else (i.e. the hand icon/
cursor)? I know there's changes coming w/ 4.5 that look promising.
I haven't bothered to download the developer preview as I really
don't want to risk is, but if some of these concerns go away with
4.5 and someone can just email me them (instead of breaking NDA on
the list), that'd be fine, too. ([email protected]).
This doesn't require 4.5, so no NDA conflict here.
I put this in a card script and it seems to work fine:
on mouseMove
if word 1 of the target = "field" then
if the textStyle of the mouseText contains "link" then
lock cursor
set the cursor to hand
else
unlock cursor
end if
end if
pass mouseMove
end mouseMove
With browse tool choosen the handler above works perfectly, but not
if pointer tool is choosen: in this case one gets errors (for the
second "if" line).
To avoid that,, seems that is necessary to include the case where the
mouseText is empty.
Something like the following:
on mouseMove
if word 1 of the target = "field" then
if the mouseText = empty then unlock cursor
else
if the textStyle of the mouseText contains "link" then
lock cursor
set the cursor to hand
else
unlock cursor
end if
end if
end if
pass mouseMove
end mouseMove
By the way, generally I am using the following (thanks to the help of
Éric Chatonet) which include the case of buttons and which works well
local tCode,
---------------------
on mouseMove
switch
case "button" is in the target
ShowHandCursor #
break
case the mouseText = empty --mouseText = empty -- important!
unlock cursor
break
case "link" is in the textStyle of the mouseChunk
ShowHandCursor #
break
default
ResetCursor #
end switch
end mouseMove
------------------------------
on mouseLeave
ResetCursor #
end mouseLeave
------------------------------
on ShowHandCursor
set the cursor to hand
lock cursor
end ShowHandCursor
------------------------------
on ResetCursor
unlock cursor
end ResetCursor
I prefer to set the defaultcursor to hand or to empty instead of
locking and setting the cursor. Whenever I've tried to use lock
cursor I've ended up having intermittent frozen cursor problems.
did not notice such issue, but well, I am going to pay attention to
this
Also, you might want to put in a "if the locktext of the target
then..." test, or you'll get the cursor changing over links in
unlocked fields, and when the cursor changes to hand the user will
think the link is clickable -- but it won't be.

Thank you Peter for this goog suggestion. I will keep it in mind if I
have links in unlocked fields
You seem very and rightly "user-orented" ;-))
Best regards from Grenoble
