Adding more than 1 object to frame

[Hitman Mania]

Hey, I'm almost done my long program that I've been working on all week, but I'm stuck on this tiny problem where I can't seem to add more than one shape component inside a frame at the same time.

final Rectangle recComp = new Rectangle();
final Ellipse ellipseComp = new Ellipse();
frame.add(recComp,BorderLayout.CENTER);
frame.add(ellipseComp,BorderLayout.CENTER);

The "frame.add()" that comes last is the only one that appears when I run the program, so how can I include them all?

Thanks.

u can't put 2 components in the centre using border layout. what u want to do is to create a panel with a flow or grid layout and put your 2 components in that then put the panel in the centre of your frame

What exactly is "frame"? You can't add a Rectangle to any ordinary AWT or Swing container.

^^ oh I already have that working, frame is JFrame. Everything is working in the program except when I include more than one component.

Sorry, I didn't get exactly what you meant, I tried this but it didn't work:

JPanel panel = new Jpanel();
FlowLayout Layout = new FlowLayout();
final Rectangle recComp = new Rectangle();
final Ellipse ellipseComp = new Ellipse();
recComp.setLayout(Layout);
ellipseComp.setLayout(Layout);
panel.add(Layout);

The default layouts for containers is a flow layout so you don't have to explicitly define one

Rectangle recComp = new Rectangle();
Ellipse ellipseComp = new Ellipse();
JPanel panel = new JPanel();
panel.add(recComp);
panel.add(ellipseComp);
frame.add(panel, BorderLayout.CENTER);

Its still not working :( one component works if I use frame.add(component), but none if I use panel.add(component)... Here's my full code:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;


public class GraphElementViewer 
{
	public static void main (String[] args)
	{
	      JFrame frame = new JFrame();
	      
	      final int FRAME_WIDTH  = 600;
	      final int FRAME_HEIGHT = 600;

	      frame.setSize(FRAME_WIDTH, FRAME_HEIGHT);
	      frame.setTitle("Graph Draw");
	      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	      frame.setLayout(new BorderLayout());
	      
	      // Create components and add them to the frame
	      final Rectangle recComp = new Rectangle();
	      final Ellipse ellipseComp = new Ellipse();
	      JPanel panel = new JPanel();

	      panel.add(recComp);
	      panel.add(ellipseComp);
	      frame.add(panel, BorderLayout.NORTH);
	           
	      
	      // Creates buttons
	      JButton RectangleButton = new JButton("Rectangle");
	      JButton EllipseButton = new JButton("Ellipse");
	      class GraphElementListener implements ActionListener
	      {
	         public void actionPerformed(ActionEvent event)
	         {
	            recComp.createRectangle();
	            ellipseComp.createEllipse();
	         }            
	      }
	      ActionListener listener = new GraphElementListener();
	      RectangleButton.addActionListener(listener);
	      EllipseButton.addActionListener(listener);
	   }

}

This code won't even compile.
You cant add a Rectangle to a JPanel
There's no such class as Ellipse

[ejosiah]

I'm guessing that you have created your own component classes Ellipse and Rectangle.
Lets forget about your code for now; what exactly is the problem u are trying to solve?

If you are trying to draw Rectangles and Ellipse then you don't need to create components use the java.awt.Graphics object's drawing methods to create them
