鼠标像素拾取器的实现(坐标&RGB)
环境:jdk1.2+
包:
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Font;
import java.awt.Point;
import java.awt.Robot;
import java.awt.Toolkit;
import java.awt.datatransfer.Clipboard;
import java.awt.datatransfer.StringSelection;
import java.awt.datatransfer.Transferable;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.util.Timer;
import java.util.TimerTask;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;
主类:MousePixInfo3(main内实例化)
第一步:设计界面
构造函数内渲染jframe
过程略..
第二步:调用标准库:
利用Robot.getPixelColor(x,y)方法得到Color对象;
利用MouseInfo.getPointerInfo().getLocation()得到Point对象;
利用Integer.toHexString(int i)方法将rgb值转成更易读的十六进制;
利用Timer.schedule(TimerTask timerTask)周期刷新像素信息;
第三步:扩展功能:
1.jframe置顶(Jframe.setAlwaysOnTop(true))(非聚焦)
2.esc键退出(System.exit(0))
3.空格暂停(timer.cancel())
4.L键将坐标值存入系统剪切板
5.C键将颜色值存入系统剪切板
