how to programmatically set colors of a GtkTextView

["Boncek, John" <jboncek Hunter COM>]

I'm trying to set the text color and background color of a GtkTextView.
I've read Havoc Pennington's mini-FAQ.  He gives the following example of
how to set a color in GTK 2.0:

  GdkColor color;

  gdk_color_parse ("red", &color);

  gtk_widget_modify_fg (widget, GTK_STATE_NORMAL, &color);

But this doesn't seem to work in this case, using GTK 2.2.4.  Here's the
code used, with silly colors just to make it obvious as to whether it's
working.

        // create the TextView
        m_pTextView = gtk_text_view_new();
        
        GdkColor color;

        gdk_color_parse ("red", &color);

        gtk_widget_modify_fg (m_pTextView, GTK_STATE_NORMAL, &color);

        gdk_color_parse ("blue", &color);

        gtk_widget_modify_bg (m_pTextView, GTK_STATE_NORMAL, &color);

The text view does display and accepts keyboard input but the colors
displayed are black-on-white.  The mini-FAQ also says that some widgets
use the "text" color instead of the foreground color but doesn't say how
to set that.
