Question

I have a label. I want to render image into it. But the following code would do anything.

 CardLayout cl = (CardLayout) (mainPanel.getLayout());
        cl.show(mainPanel, "newPersonaCard");
        BufferedImage myPicture = ImageIO.read(new    File("C:\\Desktop\\Documents\\Pictures\\always.jpg"));
        ImageIcon icon = new ImageIcon(myPicture);
        icon.getImage().flush();

I am using netbean designer.

Answer 1

You are right, in some cases there issue with repainting Icon in the JLabel, then you have to call,

myIcon.getImage().flush();
myLabel.setIcon(myIcon);

rest of methods is implemented in the Icon and JLabel correctly
