Custom JComponent not displaying in Custom JPanel
- by Trizicus
I've tried the add() method but nothing is displayed when I try to add Test to GraphicsTest. How should I be adding it? Can someone show me? I've included the code I'm using.
import java.awt.Color;
import java.awt.Graphics;
import java.awt.Graphics2D;
import javax.swing.JComponent;
public class Test extends JComponent
{
Test()
{
setOpaque(false);
setBackground(Color.white);
}
@Override
public void paintComponent(Graphics g)
{
super.paintComponent(g);
Graphics2D g2d = (Graphics2D) g.create();
g2d.setColor(Color.red);
g2d.drawString("Hello", 50, 50);
g2d.dispose();
}
}
import java.awt.Color;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.awt.geom.Rectangle2D;
import javax.swing.JPanel;
public class GraphicsTest extends JPanel implements MouseListener
{
private Graphics2D g2d;
private String state;
private int x, y;
GraphicsTest()
{
add(new Test());
}
@Override
public void paintComponent(Graphics g)
{
super.paintComponent(g);
g2d = (Graphics2D) g;
g2d.setColor(Color.BLACK);
g2d.drawString("STATE: " + state, 5, 15);
g2d.drawString("Mouse Position: " + x + ", " + y, 5, 30);
g2d.setColor(Color.red);
Rectangle2D r2d = new Rectangle2D.Double(x, y, 10, 10);
g2d.draw(r2d);
g2d.dispose();
}
public void setState(String state) { this.state = state; }
public String getState() { return state; }
public void setX(int x) { this.x = x; repaint(); }
public void setY(int y) { this.y = y; repaint(); }
public void mouseClicked(MouseEvent e) {}
public void mousePressed(MouseEvent e) {}
public void mouseReleased(MouseEvent e) {}
public void mouseEntered(MouseEvent e) {}
public void mouseExited(MouseEvent e) {}
}
