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:
?
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
