java - Drag and Drop event JavaFX -

i trying create drag , drop solution between treetableview , rectangles in interface. able drag row treetableview , when drag on rectangle, color of rectangle change. notified when drag not on anymore, can change color on rectangle. not able see event doing this.

for drag target have 4 different properties:

• ondragenteredproperty: called when drag gesture enters node

• ondragoverproperty: called when drag gesture progresses within node

• ondragexitedproperty: called when drag gesture exits node

• ondragdroppedproperty: called when mouse button released on node during drag , drop gesture

you can use properties define behaviour of target node, like:

rectangle rect = new rectangle(); rect.setondragentered(value -> {     // set drag-over color here });  rect.setondragexited(value -> {     // reset original color here });  rect.setondragdropped(value -> {      // reset original color here  });
