Como abrir meu DesktopPane + InternalFrame maximizado?
eu to usando no meu JInternalFrame o método this.setMaximizable(true); porém ele maximiza quando clicado, como faço pra ja abri-lo maximizado dentro do meu Frame?
Essa é outra pergunta Top 10
Para o JFrame basta fazer o seguinte
this.setExtendedState(MAXIMIZED_BOTH);Já o da janela interna o teste que eu fiz não funcionou!

Desculpe se falei de mais =/. Voou da uma olhada pq nao vi no cod onde esta maximizando o internal.
Bom, eu fiz dessa maneira, as vezes te ajuda…
No Frame que está o DesktopPane eu abro maximizado…
this.setExtendedState(MAXIMIZED_BOTH);Quando no menu dou um click sobre algum botão (nesse exemplo botão cliente), primeiro limpo o que está dentro do containner, em seguida chamo o frame interno setando em seu tamanho o mesmo que o do DesktopPane.
jDPContainer.removeAll(); //limpa o container
Dimension resolucao = jDPContainer.getSize(); //captura resolução do container
ClienteLista cliente = new ClienteLista();
cliente.setSize(resolucao); //seta a resolução da tela
jDPContainer.add(cliente); //adiciona a tela ao container
cliente.setLocation(0, 0); //seta a posição da tela
cliente.setVisible(true); //seta a visualização da tela

Não foi nada!
o código que maximixa a tela interna é
protected void createFrame() {
MyInternalFrame frame = new MyInternalFrame();
frame.setVisible(true); //necessary as of 1.3
desktop.add(frame);
try {
frame.setSelected(true);
//diz que a janela interna é maximizável
frame.setMaximizable(true);
//set o tamanho máximo dela, que depende da janela pai
frame.setMaximum(true);
} catch (java.beans.PropertyVetoException e) {}
}

thiago me parece que meu cod ta bem parecido com este…porém to recebendo NullPointer n sei pq se eu coloco o setMaximum();
[code]InternalFrame() throws PropertyVetoException{
super("NutriCampos Ltda.");
this.gui();
this.pack();
this.setVisible(true);
this.setMaximizable(true);
//this.setMaximum(true); // se eu o deixo recebo nullpointer.
}[/code]
