Quietly Scheming

The DragTile Component adds Picasa like Drag/Drop animated feedback to the basic Flex Tile behavior. Using this component, you can:

• drag to reorder items in the component
• drag from/to the component to move items into or out of the dataProvider to another component.
• drag from/to the component (with shift key pressed) to copy items into the dataProvider

Flex Beta 3 is required to view these demos.

Sample Applications using the DragTile Component:

• Picassa-like image drag/drop Demo
• Alphabet Tile Game
• Screamin’ Fireballs Dodgeball Team Manager

Known Issues/Areas for Improvement:

• right now the content has to be data driven (i.e., with a dataProvider + itemRenderer). Really, there’s no reason it couldn’t be driven purely by children (i.e., you explicitly name the children to display, like any other container). Just needs a little work.
• DragTile is based off of Container. Really, it should extend Tile, and modify its layout behavior.
• Currently assumes dataProvider is an Array. Really should work off of collections, like other flex data-driven components.
• drag/drop behavior isn’t as configurable as it should be. The Developer should be able to decide whether a drop is allowed, whether copy or move is allowed, etc.
