A few General Questions about Layouts

Question

Hey.
I'm pretty new to Swing so I don't know much. My first question is do you have to use a Layout Manager to organize components on a JPanel? Is there no pixel way to do it? Secondly, for layouts, specifically for GridBagLayouts, is there any way to display the grid for developing purposes?
Thanks in advance.

Answer 1

I'm sorry but the above code did not work. Even though I added the components, they still did not show. Anything I missed? Thanks.
My code is below:
import javax.swing.*;
public class SwingTest {
    public static void main(String[] args) {
        // Create application frame.
        JFrame frame = new JFrame();
        frame.setSize(500,500);
        JPanel foo = new JPanel(null);
     This 1 arugment constructor takes the layout manager as the argument.
     You can alternatively do this:
     JPanel foo = new JPanel();
     foo.setLayout(null);
     JLabel label1 = new JLabel("Label 1");
     label1.setLocation(10, 10);
     JLabel label2 = new JLabel("Label 2");
     label2.setLocation(10, 50);
     foo.add(label1);
     foo.add(label2);
     frame.add(foo);
        // Show frame.
        frame.setVisible(true);
}
