How to requestFocusInWindow after JOptionPane?

I have the following code:

JOptionPane.showMessageDialog(this, "Wrong format!", "Wrong format!", JOptionPane.ERROR_MESSAGE);

myJTextField.requestFocusInWindow();

The JTextField does not get focus after execution of JOptionPane, how do I fix this in a nice and clean way? My JTextField is on a JTabbedPane.

showMessageDialog blocks the EDT until you have confirmed the dialog. So the line of code you have setting the focus won't run until after the dialog is gone.

this isn't easy job move Focus betweens two Top-Level Containers, because Focus came from native OS and is asynchronous,

you have to delay this event to the invokeLater(), if without success then you have to look for Dialog Focus by @camickr
