swing效果点击下拉框自动填充文本框-白红宇

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;  
    }
