从JDialog中删除带有一些JComponents的JPanel

Question

如果创建了JPanel，然后添加了一些带有这些规则的JComponents

public class MyPanel extends JPanel {
    myButton = new MyButton()
    myButton.addXxxListener(...)
    myButton ....
    add(myButton)
}

public class MyButton extends JButton {
    //some constructors for parametrize JButton Object
    //build only JButton Object value or listener(s) are added in parent 
}
//and on runtime are all values added by using constructor or getter/setter 

然后如果我想从JDialog中正确删除这个JPanel（删除所有参考文件并将其丢弃到GC）我必须

1/1。必须从JPanel中删除JComponents，然后从JDialog中删除JPanel

2 /只是从JDialog直接删除JPanel

Answer 1

只需删除面板并且所有侦听器都应该足够，只要您不从其他对象引用任何子组件。
