Parent/Child Window Communication

[Lang Miao]

Background: I have a parent window (JFrame object) CustomerForm and a child window (JFrame object) InsertForm. InsertForm is displayed when insert button on CustomerForm is clicked.

Question:
1. When InsertForm is displayed, how can I make CustomerForm not accessible? Previously I use setFocusableWindowState( false ) but that only makes CustomerForm stays behind InsertForm; the buttons on CustomerForm are still clickable.

2. How do I pass info on InsertForm to CustomerForm? I have text fields of Name, Address, etc. Do I just use getText() and pass the values to CustomerForm's variable?

Thanks in advance

>1. When InsertForm is displayed, how can I make CustomerForm not accessible?

when InsertForm is created, next line = CustomerForm.setVisible(false);
in the constructor of InsertForm, have

  
{
setDefaultCloseOperation(JFrame.DO_NOTHING_O_CLOSE);
addWindowListener(new WindowAdapter(){
  public void windowClosing(WindowEvent e){
    CustomerForm.setVisible(true);
    this.dispose();}});
}

2. How do I pass info on InsertForm to CustomerForm?
either make InsertForm an inner class (exposing the variables to InsertForm)
or pass a reference to CustomerForm when InsertForm is created

(from CustomerForm)
InsertForm if = new InsertForm(this);
 
class InsertForm
{
  CustomerForm custForm;
  public InsertForm(CustomerForm cf)
  {
    custForm = cf;
    ...

then, in the window closing event you add the code to update CustomerForm data

Regarding your solution #1
The CustomerForm, then, will be hidden. I just want to deactive it. User still sees it but can't bring it on top or press any buttons on it
I come up with this one. Let me know if this sufficient.

CustomerForm.setFocusableWindowState( false );
CustomerForm.insertButton.setEnabled( false );

Thanks a bunch for the previous reply. Solution #2 works great.

Moving this to the Swing / AWT / SWT / JFace forum...
