java - adding action listener to an image -

i insert image jpanel. write code.

public void paint(graphics g) {      img1=gettoolkit().getimage("/users/boaz/desktop/piece.png");     g.drawimage(img1, 200, 200,null);  } 

i want add action listener picture, not have addactionlistener() method. how can without putting image in button or label?

there few options.

use mouselistener directly in jpanel

a simple dirty way add mouselistener directly jpanel in overrode paintcomponent method, , implement mouseclicked method checks if region image exists has been clicked.

an example along line of:

class imageshowingpanel extends jpanel {    // image display   private image img;    // mouselistener handles click, etc.   private mouselistener listener = new mouseadapter() {     public void mouseclicked(mouseevent e) {       // should done when image clicked.       // you'll need implement checks see region       // click occurred within bounds of `img`     }   }    // instantiate panel , perform initialization   imageshowingpanel() {     addmouselistener(listener);     img = ... // load image.   }    public void paintcomponent(graphics g) {     g.drawimage(img, 0, 0, null);   } } 

note: actionlistener can't added jpanel, jpanel not lend create considered "actions".

create jcomponent display image, , add mouselistener

a better way make new subclass of jcomponent sole purpose display image. jcomponent should size size of image, click part of jcomponent considered click on image. again, create mouselistener in jcomponent in order capture click.

class imageshowingcomponent extends jcomponent {    // image display   private image img;    // mouselistener handles click, etc.   private mouselistener listener = new mouseadapter() {     public void mouseclicked(mouseevent e) {       // should done when image clicked.     }   }    // instantiate panel , perform initialization   imageshowingcomponent() {     addmouselistener(listener);     img = ... // load image.   }    public void paintcomponent(graphics g) {     g.drawimage(img, 0, 0, null);   }    // method override tell layoutmanager how large component   // should be. we'll want make component same size `img`.   public dimension getpreferredsize() {     return new dimension(img.getwidth(), img.getheight());   } }
