title: What GUI libraries are the JetBrains using?
body: <h1>Background</h1>
  <p>I am somewhat new to Java and am enjoying using IntelliJ IDE developed by the JetBrains team.</p>
  <p>I have downloaded the source for the Community Edition, and I am trying to work out what GUI libraries they are using to get the look-and-feel.</p>
  <h1>Question</h1>
  <p>What libraries (if any) are they using to get the non-native tabs, toolbars and breadcrumb component?</p>
  <p>The panels they are using are also interesting, however I get the feeling they were developed for the project and are not a library. Is this true?</p>
  <p>Can someone provide a breakdown of what is needed to produce a similar look-and-feel in a GUI project?</p>
  <p>Does anyone have tutorials for that? All I have been able to work out so far is that they are using Swing and jGoodies.</p>
  <h1>What I Think So Far</h1>
  <p>They are using Swing and jGoodies. The <a href="http://mydoggy.sourceforge.net/" rel="noreferrer">MyDoggy project</a> is attempting to produce a similar docking framework, however I don't think this is used by IntelliJ.</p>
