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();             }       }
