ckeditor: Is it posible to make the editor grow horizontally as you write to a maximum of 345px?

Question

I tried with autogrow but it only works for vertical ( I believe ) and I also tried with resize but that only works with dragging the window

  config.extraPlugins = 'autogrow';
  config.autoGrow_minHeight = 140;
  config.autoGrow_maxHeight = 200;
  config.autoGrow_minWidth = 190;
  config.autoGrow_maxWidth = 345;
