Answer 2

I wanted to put the .gif file in a GUI but displayed with other elements. And the .gif file would be taken from the java project and not from an URL.

1 - Top of the interface would be a list of elements where we can choose one

2 - Center would be the animated GIF

3 - Bottom would display the element chosen from the list

Here is my code (I need 2 java files, the first (Interf.java) calls the second (Display.java)):

1 - Interf.java

public class Interface_for {

    public static void main(String[] args) {

        Display Fr = new Display();

    }
}

2 - Display.java

INFOS: Be shure to create a new source folder (NEW > source folder) in your java project and put the .gif inside for it to be seen as a file.

I get the gif file with the code below, so I can it export it in a jar project(it's then animated).

URL url = getClass().getClassLoader().getResource("fire.gif");

  public class Display extends JFrame {
  private JPanel container = new JPanel();
  private JComboBox combo = new JComboBox();
  private JLabel label = new JLabel("A list");
  private JLabel label_2 = new JLabel ("Selection");

  public Display(){
    this.setTitle("Animation");
    this.setSize(400, 350);
    this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    this.setLocationRelativeTo(null);
    container.setLayout(new BorderLayout());
    combo.setPreferredSize(new Dimension(190, 20));
    //We create te list of elements for the top of the GUI
    String[] tab = {"Option 1","Option 2","Option 3","Option 4","Option 5"};
    combo = new JComboBox(tab);

    //Listener for the selected option
    combo.addActionListener(new ItemAction());

    //We add elements from the top of the interface
    JPanel top = new JPanel();
    top.add(label);
    top.add(combo);
    container.add(top, BorderLayout.NORTH);

    //We add elements from the center of the interface
    URL url = getClass().getClassLoader().getResource("fire.gif");
    Icon icon = new ImageIcon(url);
    JLabel center = new JLabel(icon);
    container.add(center, BorderLayout.CENTER);

    //We add elements from the bottom of the interface
    JPanel down = new JPanel();
    down.add(label_2);
    container.add(down,BorderLayout.SOUTH);

    this.setContentPane(container);
    this.setVisible(true);
    this.setResizable(false);
  }
  class ItemAction implements ActionListener{
      public void actionPerformed(ActionEvent e){
          label_2.setText("Chosen option: "+combo.getSelectedItem().toString());
      }
  }
}

Answer 3

This work for me!

public void showLoader(){
        URL url = this.getClass().getResource("images/ajax-loader.gif");
        Icon icon = new ImageIcon(url);
        JLabel label = new JLabel(icon);
        frameLoader.setUndecorated(true);
        frameLoader.getContentPane().add(label);
        frameLoader.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frameLoader.pack();
        frameLoader.setLocationRelativeTo(null);
        frameLoader.setVisible(true);
    }
