Java - Get difference between old and new size of JFrame

After I do a resizing at a JFrame, is there any method that returns the difference between the old and new size, i.e (dx,dy) ?

If not, is there a way to get this info?

You need to know what the size was before the frame was resized, then you could use a ComponentListener to detect when the frame's size was changed.

Once the frame has "settled" you would simply need to calculate the difference from the "last resize" to now
