Field Detail |

public static final int ACTION_NONE
int
representing no action.
public static final int ACTION_COPY
int
representing a "copy" action.
public static final int ACTION_MOVE
int
representing a "move" action.
public static final int ACTION_COPY_OR_MOVE
int
representing a "copy" or
"move" action.
public static final int ACTION_LINK
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.
public static final int ACTION_REFERENCE
int
representing a "reference"
action (synonym for ACTION_LINK).
