Can anyone help me? I'm trying to create a JFrame
where I could adjust the JScrollBar
and change the view from top to bottom of the JLabel
with an ImageIcon
, including the other JLabel
that has a MouseEvent
of a JFileChooser
.
Unfortunately, my code isn't working as I thought it would. Any ideas why it does that? or is there any missing codes that I should be aware of? My only goal is to make the JScrollBar
work on both JLabels
public class DocVieweR extends JFrame {
/**
*
*/
private static final long serialVersionUID = 1L;
private JPanel contentPane;
private int yPos = 0;
/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
DocVieweR frame = new DocVieweR();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/**
* Create the frame.
*/
public DocVieweR() {
setTitle("DocVieweR");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(816, 705);
setLocationRelativeTo(null);
setResizable(false);
contentPane = new JPanel();
setContentPane(contentPane);
contentPane.setLayout(null);
JScrollBar scrollBar = new JScrollBar();
scrollBar.addAdjustmentListener(new AdjustmentListener() {
@Override
public void adjustmentValueChanged(AdjustmentEvent e) {
yPos =+ e.getValue();
}
});
scrollBar.setBounds(793, 0, 17, 676);
contentPane.add(scrollBar);
JLabel lblPHOTO1x1 = new JLabel("SELECT IMAGE");
lblPHOTO1x1.setFont(new Font("Segoe UI", Font.BOLD, 16));
lblPHOTO1x1.setHorizontalAlignment(SwingConstants.CENTER);
lblPHOTO1x1.addMouseListener(new MouseAdapter() {
@Override
public void mouseClicked(MouseEvent e) {
JFileChooser chosenFILE = new JFileChooser();
chosenFILE.showOpenDialog(null);
File getFILE = chosenFILE.getSelectedFile();
ImageIcon pic = new ImageIcon(getFILE.getAbsolutePath());
lblPHOTO1x1.setIcon(pic);
}
});
lblPHOTO1x1.setBounds(585, 228, 129, 128);
contentPane.add(lblPHOTO1x1);
JLabel lblBIODATA = new JLabel("");
ImageIcon img = new ImageIcon("resources/BIODATA_96dpi.jpg");
lblBIODATA.setIcon(img);
lblBIODATA.setBounds(0, yPos, 793, 1122);
contentPane.add(lblBIODATA);
}
}
I have been using JScrollBar when I should have been using JScrollPane. In addition, I accidentally discovered that you must add an extra line of code such as "scrollPane.setViewportView(JLabelNAME);" to make it work and I also noticed that once you move the scrollbar after you imported the image using JFileChooser, the image disappears but won't be much of a problem (a few debug might help). The contentPane.setLayout(null); and setBounds(...) aren't the problem but still gave me the idea, even though. THANK YOU FRAKCOOL!!! :D
