Hello! I hope someone can help me. Here it is the problem: I have Menu item "New" and have button btnExample. I want the following: When i click on "File->New" it executes btnExample. My code is able only to change the button title and show visual affect of clicking. But how can I actually execute it?

I have only one advice - don't do that. Don't bind GUI components in this way.

If you want two components to execute the same operation, simply pack this operation in a method and call the method from both components.

Also, use ActionListener - are you sure the user is going to press it using mouse and not keyboard? what if you add shortcuts to those buttons/components?

private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
    //My button to click on it

    jButton1ActionPerformed(evt);//this is the call for the other button to execut it
}

You should not be using a MouseListener for this.

You should be using Actions. Then you can add the Action to both the JButton and the JMemuItem.

Read the section from the Swing tutorial on How to Use Actions.

Amazing, I found my solution in your codes!

        btnExample.doClick();

This did the job for me
