java - Disposing JFrame with addActionListener using a JButton -

I have been trying to solve the ths problem from the last 3 days: /

I have A class is logged () which creates a JFrame-object

Another category named LoginTab () which is a constructor with a JFrame-object as parameter.

LoginTab ()

I want to dispose of JFrame with a button in the login tab () but addActionListener does not accept the JFrame object and I do not know why: Code:

  exit  and then send a closest request to that window. Can also be used to close the window.
