I've got a task to display painted 'eyes' with menu buttons to change their colors, and background color. Next animate them. But currently I'm stuck at painting, sinc in my JFrame I've Created JPanel containing panels with drawn eyes and buttons. Buttons are rendered properly but my eyes canvas is not shown. I've tried changing paint to paintComponent, setting contentPane differently but still nothing works.
import java.awt.*;
import javax.swing.*;
public class Main extends JFrame {
public static void main(String[] args) {
final JFrame frame = new JFrame("Eyes");
frame.setPreferredSize(new Dimension(600, 450));
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel players = new JPanel(new GridLayout(1, 3));
players.add(new JButton("Eyes color"));
players.add(new JButton("Eye pupil"));
players.add(new JButton("Background color"));
JPanel eyes = new JPanel();
Eyes e = new Eyes();
eyes.add(e);
eyes.setPreferredSize(new Dimension(600, 400));
JPanel content = new JPanel();
content.setLayout(new BoxLayout(content, BoxLayout.Y_AXIS));
frame.setContentPane(content);
content.add(players);
content.add(eyes);
// frame.getContentPane().add(content);
frame.pack();
frame.setVisible(true);
}
}
class Eyes extends JPanel {
public Eyes(){
}
public void paint(Graphics g) {
super.paintComponent(g);
Graphics2D g2d = (Graphics2D) g;
g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING,RenderingHints.VALUE_ANTIALIAS_ON);
BasicStroke bs = new BasicStroke(3.0f);
g2d.setBackground(Color.green);
g2d.setStroke(bs);
g2d.setColor(Color.yellow);
g2d.fillOval(50, 150, 200, 200);
g2d.fillOval( 350, 150, 200, 200);
g2d.setColor(Color.BLACK);
g2d.drawOval(49, 149, 201, 201);
g2d.drawOval(349, 149, 201, 201);
g2d.fillOval(125, 225, 50, 50);
g2d.fillOval(425, 225, 50, 50);
}
}
This is what I should get :
This is what I have :
When I've tried painting it directly in JFrame it works almost perfect, apart of background not being set. Why setBackgroundColor doesn't influence my drawing in any way ?
