Grab the "changed" signal of the text widget as

gtk_signal_connect(GTK_OBJECT(Widget_name),"changed",GTK_SIGNAL_FUNC(func),NULL);

void func(GtkText *obj,gpointer param_data)
{
char *text;

text = gtk_editable_get_chars(obj,0,-1);

//code to process the changed text.
// highligting code have to be managed by you.
//"text" will contain the modified text .
}
