JavaFX: Drag and Drop absolute positioning

I implemented the drag and drop ImageView feature in JavaFX. The issue which I encountered is that when ImageView is dropped on the StackPane, it gets aligned to the top left corner. Is there a way to make the ImageView appear in the exact location where it was dropped (absolute positioning)?

Assuming you have set the alignment property of the StackPane or the ImageView to TOP_LEFT you can set the margin to position the node:

StrackPane pane = ...
...
ImageView iv = ...
...
double posX = ...
double posY = ...
StackPane.setMargin(iv, new Insets(posY, 0, 0, posX));
pane.getChildren().add(iv);

However since you seem to look for absolute positioning of children, a Pane seems to be the more appropriate layout. (The layoutX and layoutY properties of the children are not ignored for Pane.)
