Field Detail

ACTION_NONE

public static final int ACTION_NONE
An int representing no action.

ACTION_COPY

public static final int ACTION_COPY
An int representing a "copy" action.

ACTION_MOVE

public static final int ACTION_MOVE
An int representing a "move" action.

ACTION_COPY_OR_MOVE

public static final int ACTION_COPY_OR_MOVE
An int representing a "copy" or "move" action.

ACTION_LINK

public static final int ACTION_LINK
An int representing a "link" action. The link verb is found in many, if not all native DnD platforms, and the actual interpretation of LINK semantics is both platform and application dependent. Broadly speaking, the semantic is "do not copy, or move the operand, but create a reference to it". Defining the meaning of "reference" is where ambiguity is introduced. The verb is provided for completeness, but its use is not recommended for DnD operations between logically distinct applications where misinterpretation of the operations semantics could lead to confusing results for the user.

ACTION_REFERENCE

public static final int ACTION_REFERENCE
An int representing a "reference" action (synonym for ACTION_LINK).
