Java Resetar cores background do Java

JrPaulino · 5 de setembro de 2019

Então... tenho um trabalho da faculdade que é desenvolver um joguinho da velha, até agora tudo certo :D, porém... coloquei para marcar a jogada que venceu a partida, negocio que quando clico em Reiniciar(Novo jogo), os botões estão resetando e as cores não.

Já cacei na internet e não encontrei nada sobre isso, alguém sabe dizer?

Quando você desativa os botões eles não ficam com a cor de background.

Já para resetar a cor quando clica no botão reiniciar, deixe dessa forma:

private void btnreiniciarActionPerformed(java.awt.event.ActionEvent evt) {
    btn1.setText("");
    btn1.setEnabled(true);
    btn1.setBackground(null);

    btn2.setText("");
    btn2.setEnabled(true);
    btn2.setBackground(null);

    btn3.setText("");
    btn3.setEnabled(true);
    btn3.setBackground(null);

    btn4.setText("");
    btn4.setEnabled(true);
    btn4.setBackground(null);

    btn5.setText("");
    btn5.setEnabled(true);
    btn5.setBackground(null);

    btn6.setText("");
    btn6.setEnabled(true);
    btn6.setBackground(null);

    btn7.setText("");
    btn7.setEnabled(true);
    btn7.setBackground(null);

    btn8.setText("");
    btn8.setEnabled(true);
    btn8.setBackground(null);

    btn9.setText("");
    btn9.setEnabled(true);
    btn9.setBackground(null);

    Limpaposicoes();
    txtvisor.setText("");
    joga = true;
    jogb = true;
}
