Heres my problem:

Theres two boxes on the main screen. Theres two boxes in the dialog
screen. I want to open the dialog screen, type something into the
boxes then press update so it will update the main screen.

I've used showInputDialog, but i want more control over the layout of
the dialog screen and also i want two text boxes in it too.

Can any1 help?

Use a Dialog(s) or JDialog(s)..

Then write a subclass of Dialog or JDialog, add the components,
listeners etc.

I think this is what i need.
Can you briefly explain how to?
Shall i inherit the class JDialog and then what?
Its confusing...

If ive created the Dialog class, and i tell it to return the value from a
textField, how can i retrieve it in the parent class...

Im confused!

Then you make it modal (with setModal(true)).
Then you put any GUI elements that you need
(two JTextFiields in your case) and OK, Cancel buttons.
Add a doModal() method which shall return
null if user cancels and a desired object (composed of
two Strings) otherwise. Add a private instance variable 'retval'
of the type that you will be returning from doModal().
In doModal you should call setVisible(true)
and afterwards - return retval;
To OK button add an action listener which will:
assign to retval current contents of the textfields
and setVisible(false);
To Cancel button add an action listener which will
assign null to retval and setVisible(false).

That's much all you need.

That's not a problem with Dialog
(or JDialog)

| 2. and also i want two text boxes in it too.

So pass an Object..

class DialogData
{
public String fieldName, fieldValue;

DialogData(String fieldName, String fieldValue)
{
this.fieldName = fieldName;
this.fieldValue = fieldValue;
}
}

/* ..in the Frame, pass the DialogData object
to the Dialog constructor, or have a Dialog
method that instantiates and returns a
DialogData object */

'Problem's solved..
