title: Delphi: custom button in custom title bar - à la Firefox/Opera main menu button
body: <p>I want to create 5 buttons in a title bar of a window using this way: <a href="http://delphihaven.wordpress.com/2010/04/19/setting-up-a-custom-titlebar/" rel="nofollow noreferrer">http://delphihaven.wordpress.com/2010/04/19/setting-up-a-custom-titlebar/</a></p>
  
  <p>Firefox has one button (the same for Opera):</p>
  
  <p><strong>Not maximized window</strong></p>

  <p><strong>Maximized window</strong></p>

  <p>How to make such buttons for my purpose? Rounded/curved, with bevels, with/without an image, with/without a gradient. Are there similar components? Do I need to make it manually? If so, then how? If it's not a button then what is it? Is there an alternative for it?</p>
