Olá pessoal, eu possuo três classes: Main (onde possui a executável), TelaPrincipal e Cadastro, eu fiz essas duas ultimas classes com a ajuda do Netbeans, pois esta IDE tem um recurso interessante e produtivo de fazer programas interativos (gráficos) com o usuário final. A TelaPrincipal é uma classe que foi feita com recursos de aplicativo MID, ou seja, ela possui uma barra de menu com opções que podem chamar novas telas. E o Cadastro é um formulário jDialog, onde ela tem a capacidade de receber Label's, Inbox's e etc.
Minha dúvida é: no MID TelaPrincipal possui o item File que dentro dele apresentam várias opções incluindo open, como é que eu faço para que ao clicar em open apareça o formulário Cadastro?
