Answer 1

public class Dialog2 extends JDialog{ JPanel panel1 = new JPanel(); BorderLayout borderLayout1 = new BorderLayout(); public Dialog2(Frame owner, String title, boolean modal) { super(owner, title, modal); try { setDefaultCloseOperation(DISPOSE_ON_CLOSE); jbInit(); pack(); } catch (Exception exception) { exception.printStackTrace(); } } public Dialog2() { this(new Frame(), "Dialog2", true);//这里设为了模态 this.setSize(10,20);//这里设对话框大小 } private void jbInit() throws Exception { panel1.setLayout(borderLayout1); getContentPane().add(panel1); }}用这个就可以了
