Question

Here is the JPanel class that is having the issue:

public class EntryDialog extends JPanel{

private static final long serialVersionUID = 1L;

MainWindow         mainWindow;
Image              background;
JButton            continueresume;
JButton            newresume;
JButton            settings;
JButton            exit;

public EntryDialog(MainWindow mainWindow){

    continueresume            = new JButton("Continue resume");
    newresume                 = new JButton("New resume");
    settings                  = new JButton("Settings");
    exit                      = new JButton("Exit");
    this.mainWindow           = mainWindow;
    this.background           = Utilities.getImage("images\\entryDialogBackground.jpg", true);

    this.setLayout(null);

    //continueresume button
    continueresume.setBounds(Utilities.getScaledWidth(1150), 
            Utilities.getScaledHeight(150), 
            Utilities.getScaledWidth(500), 
            Utilities.getScaledHeight(50));

    //newresume button
    newresume.setBounds(Utilities.getScaledWidth(1150), 
            Utilities.getScaledHeight(220), 
            Utilities.getScaledWidth(500), 
            Utilities.getScaledHeight(50));

    //settings button
    settings.setBounds(Utilities.getScaledWidth(1150), 
            Utilities.getScaledHeight(290), 
            Utilities.getScaledWidth(500), 
            Utilities.getScaledHeight(50));
    //exit button
    exit.setBounds(Utilities.getScaledWidth(1150), 
            Utilities.getScaledHeight(360), 
            Utilities.getScaledWidth(500), 
            Utilities.getScaledHeight(50));

    this.add(continueresume);
    this.add(newresume);
    this.add(settings);
    this.add(exit);

}

@Override
public void paintComponent(Graphics g){
    super.paintComponent(g);
    Graphics2D g2d = (Graphics2D) g;
    if(background != null){
        g2d.drawImage(background, 0, 0, this);
    }
    g2d.dispose();
}

This JPanel is being painted to a main frame in another class. What is happening is “background” is being painted just fine, but the buttons are not. The buttons appear once I hover over them with my mouse but until then they are invisible. I have searched for hours and not come to a solution so any help would be appreciated. Thanks!

I’d have to guess it’s happening in your paintComponent method. You’re calling super.paintComponent() will draw everything like usual including the buttons. Then you’re drawing over it with g2d.drawImage(). You should draw the background first.
