* The <code>DropTargetDragEvent</code> is delivered to a
* <code>DropTargetListener</code> via its
* dragEnter() and dragOver() methods.
* <p>
* The <code>DropTargetDragEvent</code> reports the <i>source drop actions</i>
* and the <i>user drop action</i> that reflect the current state of
* the drag operation.
* <p>
* <i>Source drop actions</i> is a bitwise mask of <code>DnDConstants</code>
* that represents the set of drop actions supported by the drag source for
* this drag operation.
* <p>
* <i>User drop action</i> 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:
* <pre>
* Ctrl + Shift -> ACTION_LINK
* Ctrl -> ACTION_COPY
* Shift -> ACTION_MOVE
* </pre>
* If the user selects a drop action, the <i>user drop action</i> is one of
* <code>DnDConstants</code> that represents the selected drop action if this
* drop action is supported by the drag source or
* <code>DnDConstants.ACTION_NONE</code> if this drop action is not supported
* by the drag source.
* <p>
* If the user doesn't select a drop action, the set of
* <code>DnDConstants</code> that represents the set of drop actions supported
* by the drag source is searched for <code>DnDConstants.ACTION_MOVE</code>,
* then for <code>DnDConstants.ACTION_COPY</code>, then for
* <code>DnDConstants.ACTION_LINK</code> and the <i>user drop action</i> is the
* first constant found. If no constant is found the <i>user drop action</i>
* is <code>DnDConstants.ACTION_NONE</code>.
