[REBOL] Re: cursor line
From: hijim:pronet at: 16-Aug-2001 22:13
Hi Anton,
I'm trying to find out what line the cursor is on in a text area. The
code calculates that by finding the number of lines in the area and then
reducing the text to that from the cursor to the end. I can find the
number of lines both times. I just can't keep the value of aa and bb
from being identical. Both variables always contain the number of lines
in the current text. How can I assign this number to a variable that
will not change?
I'd like to have this info always current, but that would mean
calculating on every keystroke. Instead I have a button to update and
display number of lines in the text area, number of pages that will go
to the printer, and (I'm hoping) what line the cursor is on.
I know the code will work if I can assign to a variable that will not
change, but COPY doesn't do it. I'm sure there's a simple answer to this.
Of course, a more direct method might be better. I've experimented with
system/view/line-info, as you suggested, but I get nothing that seems
related to the current cursor line.
Thanks,
Jim
