How do you close a frame when opening another frame in java?

Answer 1

There are many ways to accomplish this but one way I might accomplish this is with a WindowListener or WindowAdapter. Below is a skeleton structure:

package pkg;

public class ExampleMainFrame extends JDialog

{

public ExampleMainFrame(final Window parent)

{

super(parent);

// ... Do other stuff for initialization here or in another internal method

addWindowListener(new WindowAdapter()

{

public void WindowClosed(WindowEvent e)

{

(new ExampleDialog2(parent)).setVisible(true);

}

}

}

// ... Other methods

}

(In different .java source file)

package pkg

public class ExampleDialog2 extends JDialog

{

public class ExampleDialog2(final Window parent)

{

super(parent);

// ... Do other stuff for initialization here or in another internal method

}

// ... Other methods

}

Explanation:

WindowListener is an Interface - WindowAdapter is a class that defines empty method definitions for each of the methods so you can effectively define/override one of the methods and instantiate a WindowAdapter and it won't do anything but what you've overridden. In this example, I've overridden WindowClosed and upon that event occuring, it'll create and show the 2nd frame.
