1,先看效果
上面是文本框,紧挨着下面是对应的下拉框,点击下拉框时,下拉框中的item的内容自动填充到上面的文本框中.
实现代码:
Java代码
- public static JComboBox<String> comboBoxSelectedHandle(JComboBox<String> comboBox,final JTextField ipTextField){
- if(ValueWidget.isNullOrEmpty(comboBox)){
- comboBox = new JComboBox<String>();
- }
- comboBox.addMouseListener(new MouseAdapter() {
- @Override
- public void mouseClicked(MouseEvent e) {
- JComboBox<String> target=(JComboBox<String>)e.getSource();
- String selectedPort=(String)target.getSelectedItem();
- if(!ValueWidget.isNullOrEmpty(selectedPort)){
- ipTextField.setText(selectedPort);
- }
- // System.out.println(e.getSource());
- }
- });
- comboBox.addItemListener(new ItemListener() {
- public void itemStateChanged(ItemEvent e) {
- JComboBox<String> target=(JComboBox<String>)e.getSource();
- String selectedPort=(String)target.getSelectedItem();
- if(!ValueWidget.isNullOrEmpty(selectedPort)){
- ipTextField.setText(selectedPort);
- }
- }
- });
- return comboBox;
- }
2,项目
采用Java swing编写,使用maven构建
