I am developing a Java Desktop Application with GUI implemented in SWING.

I hava a JFrame. I have added three JPanels on that. One JPanel panel1 has a Start Button. Now I want to disable various componets on other JPanels when a user presses the start button on the panel1.

Now how can I access the components of those other panels from panel1.

I know that one approach is to first get the container of panel1

panel1.getParent();

Then get the components of the container

container.getComponents();

and use them as per need.

Q1. Is there any other way by which I can perform the same task? (I think this is the only way)

Q2. After getting the components list of the container, how to differentiate one container with other?
