Tenho a ClassFuncoes e peguei um método para limpar todos os textFields da JFrame que eu passar. É possível fazer isso né? Tenho o seguinte… public static void Limpa(JInternalFrame Frame) { for (int i=0; i < Fra…

Como passar uma JFrame por parametro para um metodo que está em uma classe

eu nao entendi mt bem oq vc quer… vc quer passar o JInternal ou o JFrame? Se for pra chamar esse que vc postou, é so fazer:

Limpa(nomeDoInternalFrame);

Se for com JFrame, troca o JInternalFrame por JFrame, e depois passa o nome do seu novo jframe:

Limpa(nomeDoJFrame);

Quero passar o JFrame.

testei aqui e funcionou… Vc tem que ver se esses textfields estão soltos no jframe ou em algum JPanel, no meu caso estava em um JPanel, ficou assim:

public void limpar_dados(JFrame frame) {
    for (int i = 0; i < jPanel2.getComponentCount(); i++) {
        Component c = jPanel2.getComponent(i);
        System.out.println(c); 
        //deixa isso pra ver se vai mostrar algum textField
        if (c instanceof JTextField) {
            JTextField field = (JTextField) c;
            field.setText("");
        }
    }
}

miinha saida ficou assim:

javax.swing.JTextField[,180,150,71x28,layout=javax.swing.plaf.basic.BasicTextUI$UpdateHandler,alignmentX=0.0,alignmentY=0.0,border=javax.swing.plaf.synth.SynthBorder@5c664c6e,flags=288,maximumSize=,minimumSize=,preferredSize=,caretColor=,disabledTextColor=DerivedColor(color=142,143,145 parent=nimbusDisabledText offsets=0.0,0.0,0.0,0 pColor=142,143,145,editable=true,margin=javax.swing.plaf.InsetsUIResource[top=0,left=0,bottom=0,right=0],selectedTextColor=DerivedColor(color=255,255,255 parent=nimbusSelectedText offsets=0.0,0.0,0.0,0 pColor=255,255,255,selectionColor=DerivedColor(color=57,105,138 parent=nimbusSelectionBackground offsets=0.0,0.0,0.0,0 pColor=57,105,138,columns=0,columnWidth=0,command=,horizontalAlignment=LEADING]

como vc esta fazendo isso em uma classe separada, é bom deixar o JPanel no param

public void limpar_dados(JPanel panel) {
    for (int i = 0; i < panel.getComponentCount(); i++) {
        Component c = panel.getComponent(i);
        System.out.println(c);
        if (c instanceof JTextField) {
            JTextField field = (JTextField) c;
            field.setText("");
        }
    }
}

aí vc chamaria com o nome do painel, no meu caso jPanel2

limpar_dados(jPanel2); //vai limpar os textos do panel2
