class:DropTargetDropEvent [NONE]

  • All Implemented Interfaces:
    Serializable

    public class DropTargetDropEvent
    extends DropTargetEvent
    
    The DropTargetDropEvent is delivered via the DropTargetListener drop() method.

    The DropTargetDropEvent reports the source drop actions and the user drop action that reflect the current state of the drag-and-drop operation.

    Source drop actions is a bitwise mask of DnDConstants that represents the set of drop actions supported by the drag source for this drag-and-drop operation.

    User drop action depends on the drop actions supported by the drag source and the drop action selected by the user. The user can select a drop action by pressing modifier keys during the drag operation:

       Ctrl + Shift -> ACTION_LINK
       Ctrl         -> ACTION_COPY
       Shift        -> ACTION_MOVE
     
    If the user selects a drop action, the user drop action is one of DnDConstants that represents the selected drop action if this drop action is supported by the drag source or DnDConstants.ACTION_NONE if this drop action is not supported by the drag source.

    If the user doesn't select a drop action, the set of DnDConstants that represents the set of drop actions supported by the drag source is searched for DnDConstants.ACTION_MOVE, then for DnDConstants.ACTION_COPY, then for DnDConstants.ACTION_LINK and the user drop action is the first constant found. If no constant is found the user drop action is DnDConstants.ACTION_NONE.

constructor:<init>(java.awt.dnd.DropTargetContext,java.awt.Point,int,int) [NONE]

  • DropTargetDropEvent

    public DropTargetDropEvent​(DropTargetContext dtc,
                               Point cursorLocn,
                               int dropAction,
                               int srcActions)
    Construct a DropTargetDropEvent given the DropTargetContext for this operation, the location of the drag Cursor's hotspot in the Component's coordinates, the currently selected user drop action, and the current set of actions supported by the source. By default, this constructor assumes that the target is not in the same virtual machine as the source; that is, isLocalTransfer() will return false.
    Parameters:
    dtc - The DropTargetContext for this operation
    cursorLocn - The location of the "Drag" Cursor's hotspot in Component coordinates
    dropAction - the user drop action.
    srcActions - the source drop actions.
    Throws:
    NullPointerException - if cursorLocn is null
    IllegalArgumentException - if dropAction is not one of DnDConstants.
    IllegalArgumentException - if srcActions is not a bitwise mask of DnDConstants.
    IllegalArgumentException - if dtc is null.

constructor:<init>(java.awt.dnd.DropTargetContext,java.awt.Point,int,int,boolean) [NONE]

  • DropTargetDropEvent

    public DropTargetDropEvent​(DropTargetContext dtc,
                               Point cursorLocn,
                               int dropAction,
                               int srcActions,
                               boolean isLocal)
    Construct a DropTargetEvent given the DropTargetContext for this operation, the location of the drag Cursor's hotspot in the Component's coordinates, the currently selected user drop action, the current set of actions supported by the source, and a boolean indicating if the source is in the same JVM as the target.
    Parameters:
    dtc - The DropTargetContext for this operation
    cursorLocn - The location of the "Drag" Cursor's hotspot in Component's coordinates
    dropAction - the user drop action.
    srcActions - the source drop actions.
    isLocal - True if the source is in the same JVM as the target
    Throws:
    NullPointerException - if cursorLocn is null
    IllegalArgumentException - if dropAction is not one of DnDConstants.
    IllegalArgumentException - if srcActions is not a bitwise mask of DnDConstants.
    IllegalArgumentException - if dtc is null.
