how do I do that?

Answer 1

if i open my main frame and click the add button,

When you click the button you display a modal JDialog. Then until the user closes the dialog they won't be able to access the main frame.

this.setEnabled(false);

Answer 3

Your question is not clear to me but as per my understanding I believe You want to open a dialog on button click but when you click the button a new JFrame is displayed and it becomes impossible for you to get back to the original frame.

1. Use a dialog /pop-up on your button click like JOptionPane.
   
   
2. If you want to open a JFrame on button click, making a HOME button on the newly created/opened JFrame and linking that button to main JFrame might be a good option.Closing the newly created JFrame will display the originally created JFrame anyway.

Answer 4

Use a dialog ( JDialog class) instead and make it modal. Here is some help on how to do this: http://download.oracle.com/javase/tutorial/uiswing/components/dialog.html
