Animate/scroll text

Question

I am wondering to know about how to make scrolling text. Just like text which can scroll from right to the left. How to animate text in Java GUI?

AFAIK, Java is not necessarily designed to make text animations. What you can do is to apply `AffineTransforms` to a `Label` but I'd really doubt that it would look any good. Maybe there are some libraries to support that sort of stuff. — posdef, Apr 05 '12 at 12:14

Do you want to move Text in a JTextField, in a JLabel, or move the Textfield/ the label, or move Text on the panel? In the last case: graphics.drawString is what you need. — user unknown, Apr 05 '12 at 12:24

maybe not an answer for OP, but I can't see reason, very simple by implements Swing Timer, (may be with Translucent container) and put there a JLabel, (updates to the JLabel could be from Array of Chars to avoids resize of container), for example

import java.awt.Color;
import java.awt.EventQueue;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JWindow;
import javax.swing.Timer;

public class SlideTextSwing {

    private JWindow window = new JWindow();
    private JLabel label = new JLabel("Slide Text Swing, Slide Text Swing, ..........");
    private JPanel windowContents = new JPanel();

    public SlideTextSwing() {
        windowContents.add(label);
        window.add(windowContents);
        window.pack();
        window.setLocationRelativeTo(null);
        final int desiredWidth = window.getWidth();
        window.getContentPane().setLayout(null);
        window.setSize(0, window.getHeight());
        window.setVisible(true);
        Timer timer = new Timer(20, new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {
                int newWidth = Math.min(window.getWidth() + 1, desiredWidth);
                window.setSize(newWidth, window.getHeight());
                windowContents.setLocation(newWidth - desiredWidth, 0);
                if (newWidth >= desiredWidth) {
                    ((Timer) e.getSource()).stop();
                    label.setForeground(Color.red);
                    mainKill();
                }
            }
        });
        timer.start();
    }

    public void mainKill() {
        Timer timer = new Timer(500, new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {
                System.exit(0);
            }
        });
        timer.start();
    }

    public static void main(String args[]) {
        EventQueue.invokeLater(new Runnable() {

            public void run() {
                SlideTextSwing windowTest = new SlideTextSwing();
            }
        });
    }
}
