Method Detail

fireEvent

private void fireEvent(EventTarget target,
                       Event e)

Fires event on a given target or on scene if the node is null

processingDragDetected

private void processingDragDetected()

Called when DRAG_DETECTED event is going to be processed by application

dragDetectedProcessed

private void dragDetectedProcessed()

Called after DRAG_DETECTED event has been processed by application

processDragDetection

private void processDragDetection(MouseEvent mouseEvent)

Sets the default dragDetect value

process

private boolean process(MouseEvent mouseEvent,
                        EventTarget target)

This function is useful for drag gesture recognition from within this Scene (as opposed to in the TK implementation... by the platform)

processRecognized

processDropEnd

private void processDropEnd(DragEvent de)

processTargetEnterOver

private TransferMode processTargetEnterOver(DragEvent de)

processTargetActionChanged

private void processTargetActionChanged(DragEvent de)

processTargetExit

private void processTargetExit(DragEvent de)

processTargetDrop

private TransferMode processTargetDrop(DragEvent de)

handleExitEnter

private void handleExitEnter(DragEvent e,
                             Scene.TargetWrapper target)

processKey

private boolean processKey(KeyEvent e)

startDrag

private Dragboard startDrag(EventTarget source,
                            java.util.Set<TransferMode> t)

startFullPDR

private void startFullPDR(EventTarget source)

createDragboard

private Dragboard createDragboard(DragEvent de,
                                  boolean isDragSource)
