java - Swing - Repainting of a Photo on JPanel -

hi guys, kindly ask me .

properly need refresh jpanel different photo gotten files. 1st time during adding of jpanel photo on frame - photo showed correctly ! ok

but when try change current photo dynamically 1 , refresh jpanel - see same (old) photo. , not matter place following "refreshing" part of code used:

picturepanel.repaint();

picturepanel.validate();

you can find below code:

 // create own jpanel   public class imagepanel extends jpanel {       private image image;       public image getimage() {          return image;       }       public void setimage(image image) {          this.image = image;       }       @override       public void paintcomponent(graphics g) {          super.paintcomponent(g);          if (image != null) {             g.drawimage(image, 0, 0, getwidth(), getheight(), null);          } else             system.out.println("the picture missing!");       }    } 

get photo file , add own jpanel (imagepanel)

public jpanel gettestpicture(string fromfile) {       imagepanel pp = new imagepanel();       pp.setlayout(new borderlayout());       try {          pp.setimage(imageio.read(new file(fromfile)));       } catch (ioexception e) {          e.printstacktrace();       }       return pp;    } 

and main call of jpanel:

picturepanel=gettestpicture("picture.jpg"); frame.add(picturepanel); //looks correct - photo visible. 

....

if trying repaint jpanel once more during program old photo stayed on panel. new photo not painted.

picturepanel=gettestpicture("picture.jpg"); frame.add(picturepanel); //picture.jpg - it`s showed correctly! picturepanel=gettestpicture("pic2.jpg");   picturepanel.repaint();  picturepanel.validate(); //doesn`t work ! picture.jpg on jpanel still ! 

please people me ! need understand whats wrong in code! please don`t propose use jlabel or similar.

thank in advance !!!!!

don't add new imagepanel frame, update existing one...

public class someothercomponent extends jpanel {     private imagepanel imagepanel;     //...     public someothercomponent() {         //...         imagepane = gettestpicture("picture.jpg");         add(imagepane);         //...      } 

when need change image, use like

imagepane.setimage(imageio.read(...)); imagepane.repaint();
