title: python termios mode like in 'htop, atop' utulities
body: <p>How to work with terminal window in mode when it is possible to operate with each cell by it coords? I dont know how this mode named, thats why I cant google it. Also, I know about <a href="https://stackoverflow.com/questions/4224933/htop-style-gui-with-python-how">this approach</a>, but now it is interesting for me how to work with it low level.</p>
  
  <p><strong>UPD:</strong>
  Ok, I read all the termios man page and some other docs, and the only thing I could say now - I still dont know how to make rotating bar somewhere in the terminal, ie by frames: - \ | / - .:(</p>
  
  <p><strong>UPD2</strong>
  Oh, I suddenly found it <a href="https://stackoverflow.com/questions/2122385/dynamic-terminal-printing-with-python?rq=1">there</a>:</p>
  
  <pre><code>import sys
  import time
  
  f='-\\|/'
  
  for i in range(10):
      sys.stdout.write("\r{0}".format(f[i%4]))
      sys.stdout.flush()
      time.sleep(0.5)
  </code></pre>
  
  <p>So, the last question in this topic - what about <em>any coordinates only with termios</em>?</p>
  
  <p><strong>Subquestion[SOLVED]:</strong></p>
  
  <p>When I use <code>curses</code> ie the second code listing from <a href="https://stackoverflow.com/a/2122972/1531116">this post</a> - it makes my semi-transparent terminal window no-transparent, when <code>top</code> does not do this. How to keep it transparent?</p>
  
  <p>solution: insert <code>curses.use_default_colors()</code> in the first string of <code>def pbar(window):</code>.</p>
