import gtk class scorewindow:    def __init__(self):     self.window = gtk.window(gtk.window_toplevel)     #self.window.set_size_request(800, 200)     self.window.set_resizable(false)     self.window.set_title("score card")     self.window.set_position(gtk.win_pos_center)     self.vb=gtk.vbox()      line="this rather long string containing\n\ several lines of text in c.\n\     note whitespace @ beginning of line is\  significant.this rather long string containing\n\ several lines of text in c.\n\     note whitespace @ beginning of line is\  significant."      self.go=gtk.label("textview\n")     self.lalign = gtk.alignment(0, 0, 0, 0)     self.label_result = gtk.label("  title")     #self.label_result.set_justify(gtk.justify_left)     self.lalign.add(self.label_result)      self.scrolled_window = gtk.scrolledwindow()     self.scrolled_window.set_border_width(10)     self.scrolled_window.set_size_request(300, 300)      self.scrolled_window.set_policy(gtk.policy_automatic, gtk.policy_always)     self.scrolled_window.show()     self.tv = gtk.textview()     self.tv.set_editable(1)     self.tv.set_cursor_visible(1)     self.tv.set_left_margin(30)     textbuffer = self.tv.get_buffer()     self.tv.show()     textbuffer.set_text(line)      self.scrolled_window.add_with_viewport(self.tv)       self.vb.pack_start(self.lalign, false, false, 0)     self.vb.pack_start(self.go, false, false, 0)     self.vb.pack_start(self.scrolled_window, true, true, 0)     color = gtk.gdk.color_parse('#ff8300')     self.window.modify_bg(gtk.state_normal, color)     self.window.add(self.vb)     self.window.show_all()    def main(self):     gtk.main()    if __name__ == "__main__": hello = scorewindow() hello.main()

start adding gtk.entry control above scrolled window. emulate first line of text view show.

add signal handlers move focus entry control text view when pressing e.g. enter key or cursor down.

add signal handlers move focus text view entry control when pressing cursor if you're on first line.
