AdfStampedDropTarget

public AdfStampedDropTarget(Number allowedActions,
                            String modelName)

Abstract AdfDropTarget, supporting drops onto stamped components.

Parameters:

allowedActions	-	that can be performed by this drop target
modelName	-	used to identify this dropTarget

AcceptDrag

protected Object AcceptDrag(Object dndContext,
                            Object possibleActions,
                            Object proposedAction,
                            Object pageX,
                            Object pageY)

Override to cache acceptance results based on rowKey/proposedAction combination

Parameters:

dndContext
possibleActions
proposedAction
pageX
pageY

Return:

Object

Overrides:

AdfDropTarget.AcceptDrag(Object, Object, Object, Object, Object)

AcceptDragOverrideIfRejectedByFlavor

protected Object AcceptDragOverrideIfRejectedByFlavor(AdfDnDContext dndContext,
                                                      Object originalProposedAction)

If the AcceptDrag was determined to use AdfDnDContext.ACTION_NONE based upon data flavor, this function can be overridden to provide exceptions for accepting the drag such as if the drop target supports child reordering.

Parameters:

dndContext	-	the AdfDnDContext
originalProposedAction	-	the originally-proposed AdfDnDContext action type

Return:

Object - an AdfDnDContext action type

_cleanUpDragFeedback

private Object _cleanUpDragFeedback(Object dndContext,
                                    Object dragExit)

Parameters:

dndContext
dragExit

Return:

Object

dragExit

public Object dragExit(Object dndContext)

Called while a drag operation is ongoing, when the mouse pointer has exited the operable part of the drop site for the AdfDropTarget.

Parameters:

dndContext

Return:

Object

Overrides:

AdfDropTarget.dragExit(Object)

drop

public Object drop(Object dndContext,
                   Object proposedAction,
                   Object pageX,
                   Object pageY)

Called when the drag operation has terminated with a drop on the operable part of the drop site for the AdfDropTarget

Parameters:

dndContext
proposedAction
pageX
pageY

Return:

Object

Overrides:

AdfDropTarget.drop(AdfDnDContext, Object, Number, Number)

DropOnRowKey

protected Object DropOnRowKey(Object dndContext,
                              Object proposedAction,
                              Object pageX,
                              Object pageY,
                              Object rowKey,
                              Object dropOrientation)

Override for the subclassed drop target to perform an action on the drop of rowkey. The default implementation queues the drop event with the rowkey as the dropSite.

Parameters:

dndContext
proposedAction
pageX
pageY
rowKey
dropOrientation

Return:

Object

GetAllowedActions

protected Object GetAllowedActions(Object dndContext)

Override to use the actions specified by the developer

Parameters:

dndContext

Return:

Object

Overrides:

AdfDropTarget.GetAllowedActions(Object)

GetAllowedFlavors

protected Object GetAllowedFlavors(Object dndContext)

Returns the Array of allowed AdfDataFlavors. If subclasses plan to use the default implementation of AcceptDrag, they must override this method to return their support AdfDataFlavors.

Parameters:

dndContext

Return:

Object

Overrides:

AdfDropTarget.GetAllowedFlavors(Object)

getRowKeyDataFlavor

public Object getRowKeyDataFlavor()

Returns the type of RowKey AdfDataFlavor used by this StampedAdfDropTarget

Return:

Object

Init

protected Object Init(Object allowedActions,
                      Object modelName)

Initializes the instance. Subclasses of AdfObject must call their superclass' Init

Parameters:

allowedActions
modelName

Return:

Object

Overrides:

AdfObject.Init()

NeedsRowKeyCollectionCheck

protected Object NeedsRowKeyCollectionCheck()

Returns whether a special check against the row keys is needed.

Return:

Object - true if a special check against the row keys is needed

toDebugString

public Object toDebugString()

Return:

Object

Overrides:

AdfObject.toDebugString()
