All Implemented Interfaces:

DragAwareRegion

public class BasicDragReactor
extends BasicDropRegion

A drop region that delays drag enter events to the drop client. This prevents flickering of e. g. plugin containers while a plugin is dragged over it. The delay time can be specified in the constructor. After timer expiration, the InteractionClient.dragActionTriggered(java.lang.Object, java.awt.Point) method of the parent of this drop region is called.

Method Summary

boolean	canImport() BasicDropRegion objects can always import.
boolean	dragEnter() The mouse enters the drop region while in a dragging action.
boolean	dragExit() The mouse exits the drop region while in a dragging action.
boolean	importData(java.awt.datatransfer.Transferable data, java.awt.Point p) Import will be performed by the parent itself, so we do nothing here

Method Detail

canImport

public boolean canImport()

Description copied from class: BasicDropRegion

BasicDropRegion objects can always import.

Specified by:

Overrides:

canImport in class BasicDropRegion

dragEnter

public boolean dragEnter()

The mouse enters the drop region while in a dragging action. Starts the timer.

Specified by:

dragEnter in interface DragAwareRegion

Overrides:

dragEnter in class BasicDropRegion

Returns:

Always true

dragExit

public boolean dragExit()

The mouse exits the drop region while in a dragging action. Stops the delay timer

Specified by:

dragExit in interface DragAwareRegion

Overrides:

dragExit in class BasicDropRegion

Returns:

Always true

importData

public boolean importData(java.awt.datatransfer.Transferable data,
                          java.awt.Point p)

Import will be performed by the parent itself, so we do nothing here

Specified by:

importData in interface DragAwareRegion

Overrides:

importData in class BasicDropRegion

Parameters:

data - Data to import

p - Current mouse position

Returns:

Always false
