In the menu item event handler:


addActionListener(new ActionListener() {
      public void actionPerformed(ActionEvent e) {
            otherFrame.show();
      }
});

I'm not sure if that is the problem. The made the secondary frame into a class and declared it with something like:

secframeclass newframe = new secframeclass();

is that wrong?

>>is that wrong?

No - not necessarily. Obviously you need to set the size before you show it.

Something like:


public class F extends JFrame {
      JFrame otherFrame;
      JPanel buttonPanel;


      private void setGui() {
            setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            // Create other frame
            otherFrame = new JFrame("Hello");
            otherFrame.setSize(100, 100);
            buttonPanel = new JPanel();
            JButton bnShowFrame = new JButton("Show/hide frame");
            buttonPanel.add(bnShowFrame);
            bnShowFrame.addActionListener(
                  new ActionListener() {
                        public void actionPerformed(ActionEvent e) {
                              otherFrame.setVisible(!otherFrame.isVisible());
                        }
                  });
            getContentPane().add(buttonPanel, BorderLayout.CENTER);
      }


      public static void main(String[] args) {
            F f = new F();
            f.setGui();
            f.pack();
            f.setVisible(true);
      }
}
