How to make make it smaller and add scroll pane

Explanation / Answer

Here is your solution:

TransitMap.java

import java.awt.*;

import java.awt.event.MouseAdapter;

import java.awt.event.MouseEvent;

import javax.swing.*;

public class TransitMap {

JButton tooltipButton;

ImageIcon image1 = new ImageIcon("Bala_Hissar.jpg");

JLabel imageLabel;

public TransitMap() {

JPanel topPanelLevel = new JPanel();

topPanelLevel.setLayout(new BorderLayout());

JFrame frame = new JFrame("Satellite View");

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

ImageIcon image = new ImageIcon("Fortress.jpg");

imageLabel = new JLabel(image);

tooltipButton = new JButton(image);

tooltipButton.setToolTipText("tooltip");

imageLabel.setToolTipText("Bala Hissar Forest");

imageLabel.addMouseListener(new MouseAdapter() {

@Override

public void mouseClicked(MouseEvent e) {

int x = e.getX();

int y = e.getY();

if (x > 610 && x < 660 && y > 340 && y < 390) {

imageLabel.setIcon(image1);

}

}

});

frame.getContentPane().add(new JScrollPane(imageLabel));

frame.setSize(400, 400);

frame.setVisible(true);

}

public static void main(String[] args) {

new TransitMap();

}

}

Explanation:-

Just remove the frame.pack(); and modify the "frame.getContentPane().add(imageLabel);" with "frame.getContentPane().add(new JScrollPane(imageLabel));" and add frame.setSize(400, 400); for size adjustment.

Whenever you call pack method it'll auto adjust the frame based on content size in panel.
