This tip shows you how to implement mouseDragged and mouseMove events for moving components into a frame:
import java.awt.*;import java.awt.event.*;class f extends Frame implements MouseMotionListener,MouseListener{Checkbox CB=new Checkbox("Label",true);Button BP=new Button("BUTTON_1");Button B=new Button("BUTTON");TextField TF=new TextField(10);Panel P=new Panel();List TA=new List();boolean b1=false;int c1=0;int c2=0;public f(String titlu) { super(titlu); }void init() { setLayout(null); TA.addMouseMotionListener(this); TA.addMouseListener(this); B.addMouseMotionListener(this); B.addMouseListener(this); P.addMouseMotionListener(this); P.addMouseListener(this); CB.addMouseMotionListener(this); CB.addMouseListener(this); TA.setLocation(50,50); TA.setSize(100,100);TA.add("List"); B.setLocation(100,150);B.setSize(80,40); CB.setLocation(120,370);CB.setSize(100,20); P.setLayout(new BorderLayout()); P.setLocation(100,200);P.setSize(150,150); P.setBackground(Color.yellow); P.add(BP,BorderLayout.NORTH); P.add(TF,BorderLayout.SOUTH); add(TA);add(B);add(P);add(CB); setLocation(0,0); setSize(400,400); setVisible(true); //show(); } //mouseDraggedpublic void mouseDragged(MouseEvent e) { Component C=e.getComponent(); if(b1==false){b1=true;Point p=new Point(e.getPoint());c1=p.x;c2=p.y;} Point z=new Point(e.getPoint()); Point q=new Point(C.getLocation()); C.setBounds(q.x+(z.x-c1),q.y+(z.y-c2),C.getSize(). width,C.getSize().height); } //mouseReleasedpublic void mouseReleased(MouseEvent e) { b1=false; } //mouseEnteredpublic void mouseEntered(MouseEvent e) { Cursor c1=new Cursor(Cursor.HAND_CURSOR); setCursor(c1); } //mouseExitedpublic void mouseExited(MouseEvent e) { Cursor c2=new Cursor(Cursor.DEFAULT_CURSOR); setCursor(c2); } //mouseClickedpublic void mouseClicked(MouseEvent e) { Component C=e.getComponent(); System.out.println(C); } //mouseMoved public void mouseMoved(MouseEvent e) { Component C=((Component)e.getSource()); java.util.Random r=new java.util.Random(); java.util.Random g=new java.util.Random(); java.util.Random b=new java.util.Random(); int cr=r.nextInt(255);int cg=g.nextInt(255); int cb=b.nextInt(255); Color col=new Color(cr,cg,cb); C.setBackground(col); } //mousePressedpublic void mousePressed(MouseEvent e){} }public class mouse_events{ public static void main(String[] args) { f t=new f("MOUSE EVENT"); t.init(); } }
