AdfDashboardDropTarget

public AdfDashboardDropTarget(Array<AdfDataFlavor> allowedFlavors)

AdfDashboardDropTarget for supporting drops onto the panelDashboard component.

Parameters:

allowedFlavors

-

used to identify this dropTarget

Method Detail

AcceptDragOverrideIfRejectedByFlavor

protected Object AcceptDragOverrideIfRejectedByFlavor(AdfDnDContext dndContext,
Object originalProposedAction)

Override to accept drags of direct children for reordering purposes when data flavors are not compatible.

Parameters:

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

Return:

Object - an AdfDnDContext action type

Overrides:

AdfStampedDropTarget.AcceptDragOverrideIfRejectedByFlavor(AdfDnDContext, Object)

DropOnRowKey

protected Object DropOnRowKey(Object dndContext,
Object proposedAction,
Object dropX,
Object dropY,
Object desiredDropIndexString,
Object dropOrientation)

Override for the subclassed drop target to perform an action on the drop of rowkey. This implementation queues the drop event with "children" as the dropSite and the desired drop index as the drop side index.

Parameters:

dndContext
proposedAction
dropX
dropY
desiredDropIndexString
dropOrientation

Return:

Object

Overrides:

AdfStampedDropTarget.DropOnRowKey(Object, Object, Object, Object, Object, Object)

GetAllowedFlavors

protected Array<AdfDataFlavor> GetAllowedFlavors(Object dndContext)

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

Parameters:

dndContext

Return:

Array<AdfDataFlavor> - null

Overrides:

AdfDropTarget.GetAllowedFlavors(Object)

Init

protected Object Init(Object allowedActions,
Object allowedFlavors)

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

Parameters:

allowedActions
allowedFlavors

Return:

Object

Overrides:

AdfObject.Init()

NeedsRowKeyCollectionCheck

protected Object NeedsRowKeyCollectionCheck()

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

Return:
