JPanel遍及JFrame

Question

I am designing my GUI in netbeans IDE editor. In editor i placed JPanel into JFrame . In code I have:

setContentPane(jPanel1);

after this, jPanel1 is spreaded over JFrame .

How can I position the JPanel , best with layouts, so it does not spread and overlay other components?

Answer 1

To prevent overlaying just add other componets after you set contentPane to JFrame. More precisely jpanel1 does not overlay other components, it substitutes the old content panel, containing your components.
