Evaluate Session


Drag-and-drop is a hallmark user experience feature of Macintosh. Spring, an innovative, web-inspired desktop, has ubiquitous support for drag-and-drop, including but not limited to:

  • Images from browsers or other apps
  • Local image files
  • Hyperlinked images
  • Arbitrary URLs from browsers or other apps
  • RSS Feeds (via NNW)
  • Amazon Products, Epicurious Recipes, Movies, PriceGrabber Products (via Watson)
  • Plain Text
  • Styled Text
  • Spring Objects
  • Spring Objects (Export Format)
  • Spring Object Data Files

Rich Internet Applications on Macintosh face additional drag-and-drop challenges because they need to acquire additional context before accepting or dealing with dropped items.

Beal's session features a selection of the user experience and technical design issues he faced and solved in creating Spring's ubiquitous drag-and-drop experience.
