I have a script that formats each line of a text member, setting various
properties like the font, fontsize, color, etc. Basically it's a chat
window that allows the user to format messages from others users in
order to make it easier to read. Example, messages from Bob are in red,
message from Bill are blue, italics, etc.

As new messages arrive, they are appended to the end of the members text.

Member("ChatWindow").text = Member("ChatWindow").text & RETURN & "Some
new text"

This wipes out the individual line formatting, returning everything to
the default font, color, etc. I prefer to avoid having to go line by
line, resetting the customized line properties each time a new message
is received. So is there a way to add to the text without losing the
customized line settings?

use the undocumented .setContentsAfter() or .setContentsBefore()

what I did for a chat program I wrote was get the line count before adding the
line and then formatting the text how I wanted after adding the line - the
reasoning was that I allowed a user to enter multiple lines using Shift+Enter
key (like MSN messenger) and the user's username and maybe the post time would
be appended to what they said, so it would not work getting the line count
after the fact.. this gave me a bit more formatting control, which I wanted.

lineCount = member("ChatWindow").line.count
member("ChatWindow").setContentsAfter(RETURN & "Some new text")
endLineCount = member("ChatWindow").line.count
member("ChatWindow").line[lineCount + 1].fontStyle = [#italic]
member("ChatWindow").line[lineCount.. endLineCount].color = color(255,0,0)

Perfect. Many thanks. I think I will also include your Shift+Enter
technique.
