Question

I am trying to put two components Jeditorpane and Jtextarea in Jlayeredpane. I am using Netbeans. I added jeditorpane and jtextarea in jlayeredpane and two buttons. When i click on button1 then it should show message “Hello world doing nice”.

 private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
    // TODO add your handling code here:
    jTextArea1.setText("");
    jTextArea1.setOpaque(true);
    jLayeredPane1.moveToFront(jEditorPane1);
    jEditorPane1.setText("Hello world doing nice");
}

and when click on button2 then it should show message “Hello world not doing good”.

 private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
    // TODO add your handling code here:
    jEditorPane1.setText("");
    jEditorPane1.setOpaque(true);
    jLayeredPane1.moveToFront(jTextArea1);
    jTextArea1.setText("Hello world not doing good");
}

But when i click on button1 then it shows message “Hello world doing nice” but when i click on button2 then it does not shows message “Hello world not doing good” as it should move the component to front. Could some one please tell me how to solve this. Here is source code which is partially generated by netbeans and partially written by me.
Thank you.

Answer 1

You should probably be using CardLayout instead.
