public class AjaxDraggable
extends AjaxComponent

AjaxDraggable makes HTML elements draggable. Use in conjunction with AjaxDroppable. When omitContainer is false (default), the contents nested inside of the AjaxDraggable will be made draggable. Otherwise an existing DOM element with the id specified via the id binding will be made draggable. For the scriptaculous options see http://wiki.github.com/madrobby/scriptaculous/draggable

Bindings

id	the id of the element to drag. When omitContainer is false, this is the id of the container surrounding the component content. When unspecified, a unique id will be generated.
omitContainer	if set to true, the container element will be omitted. The DOM id of the object to be made draggable must be specified with the id binding. Defaults to false.
elementName	the element to use for the container. defaults to "div".
class	the css class of the container
style	the css styles of the container
draggableObject	a java object which is passed to the AjaxDroppable when this draggable is dropped onto it.
draggableID	draggableID
starteffect	Effect, defaults to Effect.Opacity. Defines the effect to use when the draggable starts being dragged
reverteffect	Effect, default to Effect.Move. Defines the effect to use when the draggable reverts back to its starting position
endeffect	Effect, defaults to Effect.Opacity. Defines the effect to use when the draggable stops being dragged
zindex	integer value, defaults to 1000. The css z-index of the draggable item
revert	boolean or function reference, defaults to false. If set to true, the element returns to its original position when the drags ends. Revert can also be an arbitrary function reference, called when the drag ends. Specifying 'failure' will instruct the draggable not to revert if successfully dropped in a droppable.
snap	set to false no snapping occurs. Otherwise takes one of the following forms – Δi: one delta value for both horizontal and vertical snap, [Δx, Δy]: delta values for horizontal and vertical snap, function(x, y, draggable_object) { return [x, y]; }: a function that receives the proposed new top left coordinate pair and returns the coordinate pair to actually be used.
ghosting	boolean, defaults to false. Clones the element and drags the clone, leaving the original in place until the clone is dropped
handle	string or DOM reference, not set by default. Sets whether the element should only be draggable by an embedded handle. The value must be an element reference or element id. The value may also be a string referencing a CSS class value. The first child/grandchild/etc. element found within the element that has this CSS class value will be used as the handle.
change	Called just as onDrag (which is the preferred callback). Gets the Draggable instance as its parameter.
keyPress	keyPress
scroll	can be either a dom ID or a dom reference. In case of a dom reference the value must not be quoted. Set binding to "window" to scroll the window when the draggable reaches the window boundary. Set binding to "'someID'" to scroll the element with ID "someID"
