380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	32 * DND.LINK. The type of data that can be transferred is specified by subclasses of Transfer such as
380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	33 * TextTransfer or FileTransfer. The type of data transferred can be a predefined system type or it

380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	42 * <code>DragSourceListener</code> and associating it with the DragSource via DragSource#addDragListener.</p>

380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	44 * <p>When a successful move operation occurs, the application is required to take the appropriate
380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	45 * action to remove the data from its display and remove any associated operating system resources or
380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	46 * internal references. Typically in a move operation, the drop target makes a copy of the data
380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	47 * and the drag source deletes the original. However, sometimes copying the data can take a long
380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	48 * time (such as copying a large file). Therefore, on some platforms, the drop target may actually
380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	49 * move the data in the operating system rather than make a copy. This is usually only done in
380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	50 * file transfers. In this case, the drag source is informed in the DragEnd event that a
380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	51 * DROP_TARGET_MOVE was performed. It is the responsibility of the drag source at this point to clean
380af2bdd8e5 Upload of whole dwt tree Jacob Carlborg <doob@me.com> <jacob.carlborg@gmail.com> parents: diff changeset	52 * up its displayed information. No action needs to be taken on the operating system resources.</p>
