How do I open a new frame by clickingon a menu item in the first main frame? I tried it but something must be wrong since nothing happens when i click on the menu item anymore
I'm sure this is simple for you experts but it's urgent

In the menu item event handler:

addActionListener(new ActionListener() {
      public void actionPerformed(ActionEvent e) {

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() {
            // Create other frame
            otherFrame = new JFrame("Hello");
            otherFrame.setSize(100, 100);
            buttonPanel = new JPanel();
            JButton bnShowFrame = new JButton("Show/hide frame");
                  new ActionListener() {
                        public void actionPerformed(ActionEvent e) {
            getContentPane().add(buttonPanel, BorderLayout.CENTER);

      public static void main(String[] args) {
            F f = new F();
