java - Moving objects in Jframe -


i've got kind of jbutton want move, example in code:

package javaapplication19; import java.awt.*; import java.awt.container; import java.awt.event.*; import javax.swing.*; import javax.swing.jframe;   public class javaapplication19 extends jframe{     public static jbutton button=new jbutton("button");//button move     public static int x;     public static int y;     public javaapplication19(){         final container c = getcontentpane();         c.setlayout(null);         button.setbounds(100,100,100,100);         c.add(button);         //mouselistenerstart     button.addmouselistener(new mouseadapter() {     public void mousepressed(mouseevent e) {     if(!e.ismetadown()){     x = e.getx();     y = e.gety();     }     }     });     button.addmousemotionlistener(new mousemotionadapter() {     public void mousedragged(mouseevent e) {     if(!e.ismetadown()){     point p = getlocation();     button.setlocation(p.x + e.getx() - x,     p.y + e.gety() - y);     }     }     }); //mouselistenerend     }     public static void main(string[] args) {         javaapplication19 marco=new javaapplication19 ();         marco.setsize(1000,700);         marco.setvisible(true);         marco.setdefaultcloseoperation(jframe.exit_on_close);         }}

but there 2 problems. first 1 jbutton moves slower mouse. second 1 jbutton seems jump between 2 places in jframe when dragging it.

how solve these problems?

solved.

in code:

package javaapplication19; import java.awt.*; import java.awt.container; import java.awt.event.*; import javax.swing.*; import javax.swing.jframe;   public class javaapplication19 extends jframe{     public static jbutton button=new jbutton("button");//button move     public static int x;     public static int y;     public javaapplication19(){         final container c = getcontentpane();         c.setlayout(null);         button.setbounds(100,100,100,100);         c.add(button);         //mouselistenerstart     button.addmouselistener(new mouseadapter() {     public void mousepressed(mouseevent e) {     if(!e.ismetadown()){     x = e.getx();     y = e.gety();     }     }     });     button.addmousemotionlistener(new mousemotionadapter() {     public void mousedragged(mouseevent e) {     if(!e.ismetadown()){     point p = button.getlocation();\\i had put button.getlocation() instead of getlocation()     button.setlocation(p.x + e.getx() - x,     p.y + e.gety() - y);     }     }     }); //mouselistenerend     }     public static void main(string[] args) {         javaapplication19 marco=new javaapplication19 ();         marco.setsize(1000,700);         marco.setvisible(true);         marco.setdefaultcloseoperation(jframe.exit_on_close);         } }
