Method Detail

getDropComponent

public abstract javax.faces.component.UIComponent getDropComponent()

The UIComponent on which the drop occurred.

Returns:

UIComponent on which the drop occurred.

getDropSite

public abstract java.lang.Object getDropSite()

The drop-target-specific site within the drop component relative to which the drop occurred.

Please note that dropSite==null is a legal value for collection components. dropSite=null and DropOrientation==ON indicates that the drop has happened outside the data portion of the collection component and should be treated as a drop on the entire component Also note that dropSite==null and DropOrientation==AFTER indicates that the drop has happened on an empty collection component and the user intends to append the data.

Returns:

drop-target-specific site identifier relative to which the drop occurred.

getDropOrientation

public abstract DropEvent.DropOrientation getDropOrientation()

Orientations relative to the dropSite for which the drop occurred. Will be DropOrientation.ON for drop components with no internal drop site.

See Also:

getDropSite()

getDropSiteIndex

public abstract int getDropSiteIndex()

Returns the index of the drop site for drop components that index their drop site, or -1 if the drop site doesn't exist or is unindexed.

Returns:

index of the drop site within the drop compoennt.

getDropX

public abstract int getDropX()

The X coordinate of the drop, relative to the origin of the client drop component.

getDropY

public abstract int getDropY()

The Y coordinate of the drop, relative to the origin of the client drop component.

getProposedAction

public abstract DnDAction getProposedAction()

The DnDAction that the user requests the drop target perform as part of the drop

getTransferable

public abstract Transferable getTransferable()

Returns the Transferable object containing the data available to the drop.

getDropAction

public abstract DnDAction getDropAction()

The DnDAction that the drop target actually performed.

getDragComponent

public abstract javax.faces.component.UIComponent getDragComponent()

The UIComponent which initiated this drag operation.

Returns:

UIComponent which initiated this drag operation. Please note that there is no guarentee that this information always available, so this method can return null.
