Windows Graphics Foundation

During the event, David Blythe of the DirectX development team gave a very interesting talk about the upcoming 3D graphics architecture in Longhorn, the next major revision of Windows. Called Windows Graphics Foundation (WGF), this new architecture will usher in some major changes to how 3D graphics operations get handled by Longhorn. These changes extend well beyond Longhorn's Avalon technology, which will render the Windows Desktop using a GPU's 3D graphics processing power rather than the traditional 2D blitter. WGF will instead define the core 3D operations themselves.

As you can see, it has support for many basic controls, including:

- Command buttons
- Labels
- Checkboxes
- Radio Buttons
- List boxes
- Text boxes
- Sliders
- Drop-Down boxes
