I'm trying to build a user interface for a chess game. I've used a **GridBagLayout** filled with **JLabels** and the chess pieces are **ImageIcons** of the **JLabels**.

Now I would like to move the pieces by dragging it on the board. Is there a way to do this with **ImageIcons**? Or is there a better way to solve the problem?

EDIT: here is a sample code. you can notice that you can move the iconImage, but it doesn't "drag" with the mouse.
