introduce
As one of the most popular computer development languages at present, learning Java is a good choice for high-paying employment. The gadget introduced in this article mainly uses the MouseInfo class to obtain mouse information in real time and then display it on JDialog. I hope the following introduction can help you understand how to get the coordinates of the mouse on the screen, so let’s learn it together.
The code is as follows:
import java.awt.BorderLayout;import java.awt.FlowLayout;import javax.swing.JButton;import javax.swing.JDialog;import javax.swing.JFrame;import javax.swing.JPanel;import javax.swing.border.EmptyBorder;import javax.swing.JLabel;import java.awt.Font;import java.awt.Point;import java.util.Timer;import java.util.TimerTask;import java.awt.Color;public class MouseInfo extends JFrame { private final JPanel contentPanel = new JPanel(); JLabel value_x = null; JLabel value_y = null; /** * Launch the application. */ public static void main(String[] args) { try { MouseInfo info_frame = new MouseInfo(); info_frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); info_frame.setVisible(true); info_frame.setAlwaysOnTop(true); Timer timer = new Timer(); timer.schedule(new TimerTask() { @Override public void run() { Point point = java.awt.MouseInfo.getPointerInfo().getLocation(); // System.out.println("Location:x=" + point.x + ", y=" + // point.y); info_frame.value_x.setText("" + point.x); info_frame.value_y.setText("" + point.y); } }, 100, 100); } catch (Exception e) { e.printStackTrace(); } } /** * Create the dialog. */ public MouseInfo() { setTitle("/u9F20/u6807/u5750/u6807/u83B7/u53D6/u5668"); setBounds(100, 100, 217, 156); getContentPane().setLayout(new BorderLayout()); contentPanel.setBorder(new EmptyBorder(5, 5, 5, 5)); getContentPane().add(contentPanel, BorderLayout.CENTER); contentPanel.setLayout(null); JLabel lblx = new JLabel("/u5750/u6807x:"); lblx.setFont(new Font("宋体", Font.PLAIN, 15)); lblx.setBounds(22, 27, 66, 31); contentPanel.add(lblx); JLabel lbly = new JLabel("/u5750/u6807y:"); lbly.setFont(new Font("宋体", Font.PLAIN, 15)); lbly.setBounds(22, 68, 66, 31); contentPanel.add(lbly); value_x = new JLabel("0"); value_x.setForeground(Color.BLUE); value_x.setFont(new Font("宋体", Font.PLAIN, 20)); value_x.setBounds(82, 27, 66, 31); contentPanel.add(value_x); value_y = new JLabel("0"); value_y.setForeground(Color.BLUE); value_y.setFont(new Font("宋体", Font.PLAIN, 20)); value_y.setBounds(82, 68, 66, 31); contentPanel.add(value_y); }}Summarize
