java - 检测 JSplitPane 分隔线移动

Question

有没有办法检测 JSplitPane 分隔线何时移动？有没有办法为分隔线移动添加监听器？

JPanel panel1 = new JPanel();
JPanel panel2 = new JPanel();
JSplitPane sp = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, panel1, panel2);
// What do I put here to be notified if the divider in sp is moved?

我认为您正在寻找 addPropertyChangeListener来自容器。像这样的……

sp.addPropertyChangeListener(JSplitPane.DIVIDER_LOCATION_PROPERTY, 
    new PropertyChangeListener() {
        @Override
        public void propertyChange(PropertyChangeEvent pce) {}
});
