Change dragView during drag with JavaFX
0
-- 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 theNodedifferently.

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

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