Spacing with Gridbaglayout

Question

I’m putting together a layout for testing with Gribbaglayout, but I’m having difficulties with the positioning of the elements. The frame has two panel. I want the items on the left panel (Label 1, text 1...) to have a small left spacing and Label 1 to have a small upper spacing as it is "stuck". My main question is as to Weight, because I imagine that it is with him that I put this but I could not. Below the photo and the code:

  import java.awt.BorderLayout;
  import java.awt.Color;
  import java.awt.Dimension;
  import java.awt.GridBagConstraints;
  import java.awt.GridBagLayout;
  import java.awt.GridLayout;
  import javax.swing.BorderFactory;
  import javax.swing.ImageIcon;
  import javax.swing.JButton;
  import javax.swing.JFrame;
  import javax.swing.JLabel;
  import javax.swing.JPanel;
  import javax.swing.JTextField;
  import javax.swing.WindowConstants;

public class Teste{

private JButton btnCalc;
private JLabel origemText;
private JLabel destinoText;
private JPanel panel1, panel2;
private JLabel labelPanel2;
private JTextField texto1;
private JTextField texto2;

public Teste() {
    JFrame frame = new JFrame();
    frame.setTitle("teste");
    frame.setSize(1000, 500);
    frame.getContentPane().setLayout(new BorderLayout());


    origemText = new JLabel("Label 1");
    texto1 = new JTextField("Texto 1"); 
    destinoText = new JLabel("Label 2");
    texto2 = new JTextField("Texto 2");
    btnCalc = new JButton("Botão 1");

    GridBagConstraints cons = new GridBagConstraints();
    panel1 = new JPanel();
    panel1.setLayout(new GridBagLayout());
    panel1.setBorder(BorderFactory.createLineBorder(Color.BLACK, 1));
    panel1.setPreferredSize(new Dimension(180, 200));

    cons.anchor = GridBagConstraints.NORTHWEST;
    cons.gridx = 0;
    cons.gridy = 0;
    cons.weighty = 0.1;
    panel1.add(origemText, cons);

    cons.gridx = 0;
    cons.gridy = 1;
    cons.weighty = 0.2;
    cons.weightx = 0.1;
    panel1.add(texto1, cons);

    cons.gridx = 0;
    cons.gridy = 2;
    cons.weighty = 0.1;

    panel1.add(destinoText, cons);

    cons.gridx = 0;
    cons.gridy = 3;
    cons.weighty = 0.6;
    panel1.add(texto2, cons);

    cons.gridx = 0;
    cons.gridy = 4;
    cons.weighty = 9.0;

    panel1.add(btnCalc, cons);

    panel2 = new JPanel();
    panel2.setLayout(new GridBagLayout());
    panel2.setSize(200, 300);

    labelPanel2 = new JLabel("Panel 2");

    panel2.setBorder(BorderFactory.createLineBorder(Color.BLACK, 1));

    panel2.add(labelPanel2);

    frame.getContentPane().add(BorderLayout.CENTER, panel2);
    frame.getContentPane().add(BorderLayout.WEST, panel1);


    frame.setVisible(true);
    frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
}

public static void main(String[] args) {
    new Teste();
}
}

What you’re looking for is the Insets:

cons.insets = new Insets(20, 20, 0, 0);

Image example with Insets zeroed:

The same image, only now using Insets:

The weight, contrary to what you thought, it serves to deal with the size of the elements, when the window is resized. The image on the left, then has the weight of 0.5 for each image. The one on the right is 0.4 the first, and 0.6 the second, making one more cropped than the other:

Follow the code used if you want to test it:

import java.awt.*;
import javax.swing.*;
import javax.imageio.ImageIO;
import java.io.*;
import java.net.*;
import java.awt.image.BufferedImage;

class TesteInsets extends JPanel {

    JLabel soLogo, soLogo2;
    BufferedImage img, img2;

    public TesteInsets() {

        setLayout(new GridBagLayout());

        try {

        URL url = new URL("http://i.imgur.com/xIUCtPo.png");
        URL url2 = new URL("http://i.imgur.com/kmNQziR.png");

        img = ImageIO.read(url);
        img2 = ImageIO.read(url2);

        } catch (IOException e) {
        }

        soLogo = new JLabel();
        soLogo2 = new JLabel();
        soLogo.setIcon(new ImageIcon(new ImageIcon(img).
          getImage().getScaledInstance(175, 175, Image.SCALE_SMOOTH)));
        soLogo2.setIcon(new ImageIcon(new ImageIcon(img2).
          getImage().getScaledInstance(175, 175, Image.SCALE_SMOOTH)));

        GridBagConstraints c = new GridBagConstraints();

         c.weightx = 0.6;
         c.gridx = 0;
         c.gridy = 0;
         c.insets = new Insets(15, 15, 15, 0);
         add(soLogo, c);

         c.weightx = 0.4;
         c.gridx = 1;
         c.gridy = 0;
         c.insets = new Insets(15, 15, 15, 15);
         add(soLogo2, c);

    }

    public static void criarInterface() {

    JFrame janela = new JFrame("Teste Insets");
    janela.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    JComponent painelConteudo = new TesteInsets();

    painelConteudo.setOpaque(true);
    janela.setContentPane(painelConteudo);
    janela.setResizable(true);
    janela.pack();
    janela.setVisible(true);

    }

    public static void main(String[] Args) {

        javax.swing.SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                criarInterface();
            }
        });
    }

}
