Creating and Disposing of a Form's Runtime Frame
To make your form work, you have to provide a runtime frame for it. The main() method for GUI forms takes care of creation and disposal of such frame.
To create a main() method for a form
Open for editing the bound class of a form where you want to create the main() method.
Press Alt+Insert.
On the pop-up menu, click Form main(). The following method is added to the source code:
public static void main(String[] args) { JFrame frame = new JFrame("<class name>"); frame.setContentPane(new <class name>().contentPane); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.pack(); frame.setVisible(true); }
