Hey, I am developing an applet which simulates the behavior of certain communication protocols. The applet would allow users to configure a network made up of hosts and routers connected by links. These network components would be placed onto a network configuration area using drag and drop. I was able to implement that feature, but i am having problems drawing lines between these components which represent links. Whenever i try to draw on the network configuration area, the components(which is a class inheriting from the JLabel class) on the area are blocked out and only the line drawn remains. I would really appreciate any help. Thanks in advance.
