I just wondered if anybody knows if it is possible to have movable objects (ie using the mouse) inside a JFrame. By movable object I mean just a plain rectangle or something. Any link to some code of something will do. Cheers
Yes, you can do this by using a MouseMotionListener and updating the object's location in the mouseMoved() or mouseDragged() methods. You can display your object in one of two ways... override paintComponent() and paint a rectangle based off the x, y coordinates updated in your MouseMotionListener, or just setLayout( null ) on a JPanel and add another JPanel inside it, with setOpaque( true ), location set using setBounds( x, y, width, height ), and color set using setBackground().
