Subject: Gtk::TextBuffer colorful

Hello,

is there any way to bring some color into the Gtk::TextView for some lines?

example:
this line is black
this line is black
this line is red
this line is black
...

I use the Gtk::TextBuffer.insert_at_cursor(text) function, because I 
generate a lot of lines dynamically.

@textv_w =  @glade.get_widget("textview1")
@buf = @textv_w.buffer


but if I like to change the color ...

def text_color(color)
    #Gdk::flush
    @textv_w.modify_text(Gtk::STATE_NORMAL, Gdk::Color.parse(color))
    @buf= @textv_w.buffer
end


@buf.insert_at_cursor("this should be black")
text_color("red")
@buf.insert_at_cursor("this should be red")
text_color("black")
@buf.insert_at_cursor("this should be black again")

... the whole thing is black.

I even tried to use the TextBuffer.text=(text) function.
Gdk::flush does not work at all.
Is there any way to flush the buffer before changing the color like 
$stdout.flush?


Thanks!

Karl
