Attributes


          
[noscript] attribute unsigned long dropEffectInt

          
[noscript] attribute unsigned long effectAllowedInt
 Sets the drag cursor state. Primarily used to control the cursor during
 tab drags, but could be expanded to other uses. XXX Currently implemented
 on Win32 only.

 Possible values:
  auto - use default system behavior.
  default - set the cursor to an arrow during the drag operation.

 Values other than 'default' are indentical to setting mozCursor to
 'auto'.
attribute DOMString mozCursor
 The number of items being dragged.
readonly attribute unsigned long mozItemCount
 Will be true when the user has cancelled the drag (typically by pressing
 Escape) and when the drag has been cancelled unexpectedly.  This will be
 false otherwise, including when the drop has been rejected by its target.
 This property is only relevant for the dragend event.
readonly attribute boolean mozUserCancelled

Methods

 Creates a copy of the data transfer object, for the given event type and
 user cancelled flag.
[noscript] nsIDOMDataTransfer clone(in PRUint32 aEventType, in PRBool aUserCancelled)
 Remove the data associated with the given format for an item at the
 specified index. The index is in the range from zero to itemCount - 1.

 If the last format for the item is removed, the entire item is removed,
 reducing the itemCount by one.

 If format is empty, then the data associated with all formats is removed.
 If the format is not found, then this method has no effect.

 @param format the format to remove
 @throws NS_ERROR_DOM_INDEX_SIZE_ERR if index is greater or equal than itemCount
 @throws NO_MODIFICATION_ALLOWED_ERR if the item cannot be modified
void mozClearDataAt(in DOMString format, in unsigned long index)
 Retrieve the data associated with the given format for an item at the
 specified index, or null if it does not exist. The index should be in the
 range from zero to itemCount - 1.

 @param format the format of the data to look up
 @returns the data of the given format, or null if it doesn't exist.
 @throws NS_ERROR_DOM_INDEX_SIZE_ERR if index is greater or equal than itemCount
nsIVariant mozGetDataAt(in DOMString format, in unsigned long index)

          
void mozSetDataAt(in DOMString format, in nsIVariant data, in unsigned long index)
 Holds a list of the format types of the data that is stored for an item
 at the specified index. If the index is not in the range from 0 to
 itemCount - 1, an empty string list is returned.
