檢測JSplitPane分割器移動

Question

有沒有辦法檢測何時移動JSplitPane分隔線？ 有沒有辦法為分頻器移動添加一個監聽器？

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?

Answer 1

我想你正在從Container尋找addPropertyChangeListener 。 像這樣......

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

Answer 2

使用

splitter.addPropertyChangeListener("dividerLocation", myListener);
