Indsætte billede i GUI

prøv:

wherever.add(new JLabel(new ImageIcon(new URL(urlstr))));

import javax.swing.ImageIcon;
import javax.swing.JLabel;
import java.net.MalformedURLException;
import java.net.URL;

jPanel1.add(new JLabel(new ImageIcon(new URL("http://www.google.dk/images/nav_logo3.png"))));

Den viser ingen ting udover en grå JFrame.

Følgende virker fint hos mig:

import java.awt.BorderLayout;
import java.net.MalformedURLException;
import java.net.URL;

import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;

public class Pic extends JFrame {
    public Pic() throws MalformedURLException {
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        getContentPane().setLayout(new BorderLayout());
        JPanel p = new JPanel();
        p.add(new JLabel(new ImageIcon(new URL("http://www.google.dk/images/nav_logo3.png"))));
        getContentPane().add(p, BorderLayout.CENTER);
        pack();

    }
    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                try {
                    Pic f = new Pic();
                    f.setVisible(true);
                } catch (MalformedURLException e) {
                    e.printStackTrace();
                }
            }
        });
    }
}

Det virker også.

Tak for hjælpen.
