jdk.awt.dnd.DropTargetDragEvent — clojure-interop/java.awt 1.0.5

The DropTargetDragEvent is delivered to a DropTargetListener via its dragEnter() and dragOver() methods.

The DropTargetDragEvent reports the source drop actions and the user drop action that reflect the current state of the drag operation.

Source drop actions is a bitwise mask of DnDConstants that represents the set of drop actions supported by the drag source for this drag operation.

User drop action 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:

Ctrl Shift -> ACTION_LINK Ctrl -> ACTION_COPY Shift -> ACTION_MOVE If the user selects a drop action, the user drop action is one of DnDConstants that represents the selected drop action if this drop action is supported by the drag source or DnDConstants.ACTION_NONE if this drop action is not supported by the drag source.

If the user doesn't select a drop action, the set of DnDConstants that represents the set of drop actions supported by the drag source is searched for DnDConstants.ACTION_MOVE, then for DnDConstants.ACTION_COPY, then for DnDConstants.ACTION_LINK and the user drop action is the first constant found. If no constant is found the user drop action is DnDConstants.ACTION_NONE.

->drop-target-drag-event clj

(->drop-target-drag-event dtc cursor-locn drop-action src-actions)

Constructor.

Construct a DropTargetDragEvent given the DropTargetContext for this operation, the location of the "Drag" Cursor's hotspot in the Component's coordinates, the user drop action, and the source drop actions.

dtc - The DropTargetContext for this operation - java.awt.dnd.DropTargetContext cursor-locn - The location of the "Drag" Cursor's hotspot in Component coordinates - java.awt.Point drop-action - The user drop action - int src-actions - The source drop actions - int

throws: java.lang.NullPointerException - if cursorLocn is null

accept-drag clj

(accept-drag this drag-operation)

Accepts the drag.

This method should be called from a DropTargetListeners dragEnter, dragOver, and dropActionChanged methods if the implementation wishes to accept an operation from the srcActions other than the one selected by the user as represented by the dropAction.

drag-operation - the operation accepted by the target - int

data-flavor-supported? clj

(data-flavor-supported? this df)

This method returns a boolean indicating if the specified DataFlavor is supported.

df - the DataFlavor to test - java.awt.datatransfer.DataFlavor

returns: if a particular DataFlavor is supported - boolean

get-current-data-flavors clj

(get-current-data-flavors this)

This method returns the current DataFlavors from the DropTargetContext.

returns: current DataFlavors from the DropTargetContext - java.awt.datatransfer.DataFlavor[]

get-current-data-flavors-as-list clj

(get-current-data-flavors-as-list this)

This method returns the current DataFlavors as a java.util.List

returns: a java.util.List of the Current DataFlavors - java.util.List<java.awt.datatransfer.DataFlavor>

get-drop-action clj

(get-drop-action this)

This method returns the user drop action.

returns: the user drop action - int

get-location clj

(get-location this)

This method returns a Point indicating the Cursor's current location within the Component's coordinates.

returns: the current cursor location in Component's coords. - java.awt.Point

get-source-actions clj

(get-source-actions this)

This method returns the source drop actions.

returns: the source drop actions - int

get-transferable clj

(get-transferable this)

This method returns the Transferable object that represents the data associated with the current drag operation.

returns: the Transferable associated with the drag operation - java.awt.datatransfer.Transferable

throws: java.awt.dnd.InvalidDnDOperationException - if the data associated with the drag operation is not available

reject-drag clj

(reject-drag this)

Rejects the drag as a result of examining either the dropAction or the available DataFlavor types.
