How to know my dialog has changed

Question

I have a Jdialog componenet with various textfields,passwordfield,a few checkboxes and listboxes.
I have two buttons at the bottom saying ok and cancel
ok button updates the new info from the dialog and updates the database.
How do i identify whether the dialog components have really undergone a change so that i dont update my database with values which were never modified
thanx in advance

Answer 1

I am assuming the following things.
1) you instantiate your JDialog from your parent frame.
like this.
JDialog yourNewDialog = new JDialog();
yourNewDialog.show();
This makes your dialog appear.
You can make the following changes.
If the dialog is modal.
you can add a method which returns a integer in the JDialog Box
int value = 1;
public int okOrCancel(){
return value;
update value = 1 in actionperformed of the Ok button to 1 and value = 2 in actionperformed of the Cancel button
in your main program:
U can call the method
yourNewDialog.okOrCancel() and know which button was pressed.
Hope this helps.
