JFrame hided after closing his child

Question

I googled this problem a lot but can't find any answers. I have legacy system with three JFrame objects. They were created in one chain: first JFrame is parent for second one, second is parent for third.

The problem is after I close third window, the first window receive focus and the second one is going behind the first. And its wrong. I expect that after closing third JFrame focus will go to the second window. What could be the problem and how to fix this wrong behaviour?

Code looks something like this:

Frame first = new JFrame(null, "first");
JDialog second = new JDialog(first, "second"); 
JFrame third = new JFrame(second, "third");

third.addWindowListener(new WindowAdapter() {
  // request focus in second window when focus lost in third
});

Can you put a `WindowsListener` on closing `jframe2.requestFocusInWindow()` ? — nachokk, Apr 08 '14 at 14:31
the second window is instance of JDialod class. And it doesn't receive events in WindowListener. Even after dialog.requestFocus() or dialog.requestFocusInWindow(). — yu.pitomets, Apr 09 '14 at 09:20

Using several JFrame objects in one application is a bad practice. See the following answer, that could help to change your implementation. https://stackoverflow.com/a/9554657/2239537

It's very difficult to change implementation if project was started in 1996. The project is really very big. – yu.pitomets Apr 08 '14 at 14:11
