Conforme imagem abaixo, tenho o seguinte problema e não estou conseguindo implementar.
Tenho o seguinte…
um JInternalFrame,e dois JPanel em classes separadas, uma de listagem de cliente e outra de adicionar cliente.
por questão de estética, me foi solicitado que ao clicar em um botão ou outro, alterne o conteúdo da tela.
inicialmente pensei em alternar a visibilidade dos JPanel.
Alguém já fez algo do tipo, tem algum exemplo p/ compartilhar?
Use um CardLayout, ou melhor ainda, use um JTabbedPane. Exemplo de um CardLayout:
