Handle event from another class (java)

Question

i'm at a standstill developing a java application. I have a series of JFrames that open each other, and once I open the next, the frame before shall close. Now, all works fine, I used

setVisible(false);

to "close" the frame, but I have some problems with a specific form I generated: The form has some panels inside, and the panels each have a button which opens the next form. Now, I wonder how can I apply setVisible(false) to the form that contains those panels.

ChooseForm is the name of the form that contains the panels; And I have this event handling the button click of each panel's button

private void btn_scegliMouseClicked(java.awt.event.MouseEvent evt) {                                        
    Database.getAbitazioneByCodice(label_codice.getText());
    MainForm.showFrame();

}

Thanks in advance for the help.

You may use `SwingUtilities.getWindowAncestor` : https://docs.oracle.com/javase/7/docs/api/javax/swing/SwingUtilities.html#getWindowAncestor(java.awt.Component) — Arnaud, May 29 '17 at 15:19

There are many ways to do this. A Simple way you can do like this:

class YourFrame extends JFrame implements ActionListener {

    private YourPanel panel;

    public YourFrame() {
        //...
        panel.addButtonActionListener(this);
    }

    public void actionPerformed(ActionEvent e) {
        //show other Frame and hide this Frame
    }
}
class YourPanel extends JPanel {
    private JButton yourButton;

    public void addButtonActionListener(ActionListener listener) {
        yourButton.addActionListener(listener);
    }
}
