Write a part of a program which in case of mouse click highlights the closest rectangle to the mouse. The distance from the mouse position is calculated using the centre of the rectangle.

Helpful stuff:

<pre>
 +
Rectangle object – all the shapes in the given pane is guaranteed to be of that shape. Subclass of Node.
 +
r.getX(), r.getY() – x (left side) and y (upper side) for the rectangle r
 +
r.getWidth(), r.getHeight() – width and height of the rectangle r.
 +
ObservableList<Node> pane.getChildren() – returns a list of all the children (in our case, all the rectangles).
 +
For highlighting: r.setFill(Color.RED) can be used, where r is the object to be highlighted.
