Field Detail

Cancel

public static final long Cancel

The drag will be cancelled.

Constant Field Values

Forbidden

public static final long Forbidden

The drag will be cancelled. Use this operation to signal that this interaction would *normally* perform a different operation, but that it explicitly forbids a drop at this specific time and place. This may cause a special symbol to be displayed on the drag image.

Constant Field Values

Copy

public static final long Copy

The data represented by the drag item(s) will be copied. This is the most common operation to use.

Constant Field Values

Move

public static final long Move

The data represented by the drag item(s) will be moved.

You may use this only if UIDropSession's allowsMoveOperation is true. Otherwise it will be treated as UIDropOperationCancel.

Note that the system does not give any special meaning to this operation. The delegates of both the UIDragInteraction and UIDropInteraction must cooperate to produce the correct result. For instance, the UIDropInteraction's delegate might insert the data in the new location, and the UIDragInteraction's delegate might remove the data from the old location.
