| Not sure exactly what you are trying to do but it sounds like you want
word that is clicked on.
Quick and dirty way would be:
$scrolled->selectWord();
my $word = $scrolled->getSelected();
The above will only get a single word, so would be a challenge if you
have a link with multiple words.
Lame way:
create a separate tag for each word and bind that to a sub for that
particular word. These seems like
a lot of overhead and I would imagine Text widget would have better
feature you can leverage on.
Efficient way:
? I will leave that up to you ;) or someone else more Text widget savvy
then myself.
Like I mentioned before I had never tried the link thing, just gave it a
quick try yesterday as a
proof that it could be done. Maybe some one else on the list could
provide a better solution. You should
be able figure out where your cursor is and then determine from there. I
don't use Text widgets very often
in my UI's, only occasionally to display output from child processes
that I am running via some IPC.
So I have limited knowledge of the feature set of the Text widget. You
may want to check the documentation.

Mike

i have a textfield where i have multiple pieces of text tagged with
'LINK'
$scrolled->tagBind('LINK',"<Button-1>",sub { print
$scrolled->GetTextTaggedWith( 'LINK' ) } );
thus the above line prints all LINK-tagged texts how do i get to the
text of the specific link i klik on ?
thanks for your help
kind regards
