The colour of GtkText box text

[Aaron Kennedy <aaronk t131 aone net au>]

Hi all,

Ok, I don't mean to sound repetative, but does anyone have any idea on
how to work out what the colour of a particular piece of text in a
GtkText box is.
Also, is it possible to alter the colour of a piece of text without
using gtk_text_forward_delete() to remove it and reinsert it with
gtk_text_insert() in a difference colour?  For example, if someone typed
"hello" in a GtkText box, and the program detected that hello had been
typed, how would it change it to, say green, without deleting it and
re-entering it.

Thanks for the help.

Aaron
