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_MOVEIf 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
.
