    Default Showing an Image on screen

    Hi all,

    I am trying to do a simple combobox which according to what is selected an image is shown. This is working however I have to minimize and maximize the window so that the image is shown. Moreover if 2 different choices are done on the same run both pics are being shown on the panel. Can you please help?

    Here is the code:

     import javax.swing.*;
     import java.awt.event.*;
     
     public class Images extends JFrame implements ActionListener {
         String[] formats = {"Green","Red"};
         JComboBox formatBox = new JComboBox();
          JPanel pane = new JPanel();
           JLabel formatLabel;
        public Images() {
            super("Door Choice");
            setSize(220, 300);
            setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);        
            formatLabel = new JLabel("Choose door type:");
            pane.add(formatLabel);
            for (int i = 0; i < formats.length; i++){
                 formatBox.addItem(formats[i]);
            }
     
     
            pane.add(formatBox);
            formatBox.addActionListener(this);
            add(pane);
            setVisible(true);
         }
           public void actionPerformed(ActionEvent ae)
        {
     
                     ImageIcon myDoor= new ImageIcon("C:\\Users\\Projector\\Desktop\\Doors\\"+formatBox.getSelectedItem()+".png");
                     JLabel myImage = new JLabel(); 
                     myImage.setIcon(myDoor);
                     pane.add(myImage);
     
            }
     
         public static void main(String[] args) {
            Images image = new Images();
     
        }
    }

    Default Re: Showing an Image on screen

    You are creating a new JLabel each time, then adding it to the pane (which I'm surprised works without calling revalidate). Is that really what you want to do?
