Change dragView during drag with JavaFX

-- EDIT



I just found out that it is not possible, but is there anything else I can do to generate visuals like I want?



I'm using JavaFX to set a dragView on the DragBoard, but I can't seem to find a way to change that image during a drag operation.



I've tried to use setDragView(MyImage) when the drag over event was fired, but that didn't work.



Is this at all possible, or should I find another way?



Code below:



// Called when drag starts
public void handleBlockDragDetected(PuzzleBlockView puzzleBlockView, PuzzleBlock puzzleBlock, GridPane blockPane)
{
ClipboardContent clipboardContent = new ClipboardContent();
clipboardContent.put(GameController.BLOCK_FORMAT, puzzleBlock);

Dragboard dragboard = blockPane.startDragAndDrop(TransferMode.MOVE);
dragboard.setDragViewOffsetX(20);
dragboard.setDragViewOffsetY(20);
dragboard.setDragView(puzzleBlockView.getSnapshot());
dragboard.setContent(clipboardContent);

blockPane.setVisible(false);
draggingBlock = puzzleBlockView;
}

// Called on dragOver detected
public void handleBlockDragOver(DragEvent event)
{
Dragboard dragboard = event.getDragboard();

if (dragboard.hasContent(BLOCK_FORMAT) && draggingBlock != null) {
dragboard.setDragView(new Image(getClass().getResource("/img/flag.png").toString()));

event.acceptTransferModes(TransferMode.MOVE);
}
}

  • Are you trying to indicate to the user the current target can accept the drop? If so, you could style the Node differently.

  • I want to change the dragView image to display on which tile inside the block collides with another tile on the grid.
