WoW:Viewing Blizzard's WoW user interface code

Extracting FrameXML locally

• Download Blizzard's UI Customization Tool (Follow the Support Tools link on http://www.worldofwarcraft.com/ )
  • This direct link should also work.
• Run it, click the appropriate button(s)
• When it's done look in World of Warcraft/Interface/FrameXML
  • Textures are a bunch of .blp files. google for 'blp warcraft'to get an idea of what this means

Burning Crusade

• If you wish to extract the Burning Crusade beta UI files, use this direct link Source

Note that this will only work with the beta version of the game, not the current release nor the final version.

Viewing FrameXML on the web

• http://wdn.wowinterface.com keeps a database of all versions of FrameXML online. You can compare different versions to each other, view the contents of specific files (in a specific interface version), or just download the entire interface as it looked for a given version. Even test server versions are available.
