Arquivo Discussoes de Programacao e Tecnologia Em meu projeto faço a criação de um JDialog e outros componentes(ScrollPane, Panel, Jlabels e JTextField) dentro dele em tempo de execução baseados nos valores de uma matriz que construo com o decorrer da programação da aplicação.
Minha dúvida é a seguinte, nessa nova interface que criei eu precisava alterar o valor do JTextField e gravá-lo assim geraria meu arquivo .json. Isso é possível?
Fico no aguardo e desde já agradeço.
É uma pergunta a ser feita ao seu espelho.
Como é que você referencia os componentes criados em tempo de execução? Guarda referências a ele em listas, ou em variáveis?
A principio guardei a criação dos componentes em uma matriz.
Vou postar o código para melhor entendimento:

RESOLVIDO!
A resposta estava debaixo do meu nariz…
Segue código:
@Override
public void actionPerformed(ActionEvent e) {
String key = null, value = null;
for (int i=0; i<componentes.length;i++){
for(int j=0;j<2;j++){
if(j==0)
//System.out.println(">>"+String.valueOf(((JLabel)componentes[i][j]).getText()));
key = String.valueOf(((JLabel)componentes[i][j]).getText());
else
value = String.valueOf(((JTextField)componentes[i][j]).getText());
}
if (!key.equals(""))
doc.put( key, value);
}
try {
db.saveDocument(doc);
dialog.dispose();
} catch (IOException ex) {
Logger.getLogger(AddToJScrollPane.class.getName()).log(Level.SEVERE, null, ex);
}
}
