How to create a search bar similar to Google search style in JAVA GUI
提问by Paul Ang
I am trying to create a search feature in my program similar to google search bar, where when user is typing it actually searches the database and displays the current result in a pop-out list below the JTextField. I am new to java GUI programming therefore I am unclear about all the java components therefore it is hard to find suitable components which fulfil my needs, especially the component I need to use for the pop out drop down list below the text field. I hope some experts can show me some insight.
我正在尝试在我的程序中创建一个类似于 google 搜索栏的搜索功能，当用户输入时，它实际上会搜索数据库并在JTextField. 我是 Java GUI 编程的新手，因此我不清楚所有的 Java 组件，因此很难找到满足我需求的合适组件，尤其是我需要用于文本字段下方弹出下拉列表的组件。我希望一些专家可以给我一些见解。

SwingX API would helpful to solve this issue. You can use the following code to implement auto complete feature to editable ComboBox.
SwingX API 将有助于解决这个问题。您可以使用以下代码为可编辑的 ComboBox 实现自动完成功能。
import javax.swing.*;
import org.jdesktop.swingx.autocomplete.AutoCompleteDecorator;
import java.awt.*;
public class Demo {
JFrame frame = new JFrame("");
AutoCompleteDecorator decorator;
JComboBox combobox;
public Demo() {
combobox = new JComboBox(new Object[]{"","Ester", "Jordi",
"Jordina", "Jorge", "Sergi"});
AutoCompleteDecorator.decorate(combobox);
frame.setSize(400,400);
frame.setLocationRelativeTo(null);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLayout(new FlowLayout());
frame.add(combobox);
frame.setVisible(true);
}
public static void main(String[] args) {
Demo d = new Demo();
}
}
