show / print tree in a JtextField or JAVA text box

Navigation
1

cordial greeting,

I need someone to help me print or show the data of a tree in java in a jtextfield,

the impression in each of its paths (inorden, preorder, postOrder) by console normal print, but when it comes to mount it in interface mode and want to show it in a jtextield throws too many errors, I need your help to finish this small software,

the code is as follows

the one in the InOrden route 

public void inorden(Arbol raiz)
    {

    if(raiz==null)
        {
        return;
        }
    else
        {
            inorden(raiz.izq);
            System.out.println(raiz.letra);
            inorden(raiz.der);
         }
    }

until here everything prints normal by console the tree, but the idea is to print it or show it by interface mode, I think that in a jtextield it should appear, but I have not been successful, 

private void btn_inordenActionPerformed(java.awt.event.ActionEvent evt) {

    // TODO add your handling code here:



    inorden(raiz); // aca llamo el metodo recursivo

    panelImpresion.setVisible(true); // muestro el panel donde se encuentra en jtextField llamado txt_impresion

    txt_impresion.setText(raiz); // solo muestra la raiz,



}

I have also tried to store inorden (root) in a String to concatenate it and then call it in the txt_impresion, but neither, is there any way to show it as I am trying it or is it only by console ???? please help ....

I leave an image of the program, any suggestion is welcome, in advance thank you very much

Replaces the line of the code 

System.out.println(raiz.letra);

By 

txt_impresion.setText(txt_impresion.getText() + "-->" + raiz.letra);
