Thread: Help with GridBagLayout

This is my first attempt at using the GridBagLayout. Here is a screen shot of the program I made with C# that I am trying to remake in Java:

Here is my code:

package ISAPI;
 
import java.awt.BorderLayout;
import java.awt.Container;
import java.awt.Dimension;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.GridLayout;
 
import javax.swing.JButton;
import javax.swing.JComboBox;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JTextArea;
import javax.swing.JTextField;
 
public class MainFrame extends JFrame 
{
 
	final int WIDTH = 850;
	final int HEIGHT = 600;
	private String[] ComboArry ={" ", "IAgentManagement", "IContactManagment", "ISessionManagement"};
	public MainFrame(String title)
	{
		super(title);
		Dimension size = getPreferredSize();
		size.width = WIDTH;
		size.height = HEIGHT;
		setPreferredSize(size);
 
		JLabel hostLabel = new JLabel("IS Host");
		JLabel generatedLabel = new JLabel("Generated URL to Post to integration Services");
		JLabel responseHtmlLabel = new JLabel("Response from the API in HTML");
		JLabel responseTextLabel = new JLabel("Response from the API in Text");
		JLabel interfaceLabel = new JLabel("Interface");
 
		JTextField hostTextField = new JTextField(22);
 
		JTextArea generatedTextArea = new JTextArea(3, 20);
		JTextArea responseHTMLTextArea = new JTextArea(10, 10);
		JTextArea responseTextTextArea = new JTextArea(10, 4);
 
		JButton createURLButton = new JButton("Create URL");
		JButton postButton = new JButton("Post");
 
		JComboBox interfaceBox = new JComboBox(ComboArry);
		interfaceBox.setPreferredSize(new Dimension(250,20));
 
		ActivityPanel Ap = new ActivityPanel();
 
		Container pane = getContentPane();
		pane.setLayout(new GridBagLayout());
		GridBagConstraints gc = new GridBagConstraints();
 
		//first row
 
		gc.fill = GridBagConstraints.HORIZONTAL;
		gc.weightx = 0.2;
		gc.weighty = 1;
		gc.gridx = 0;
		gc.gridy = 0;
		add(hostLabel, gc);
 
 
		gc.fill = GridBagConstraints.HORIZONTAL;
		gc.weightx = 0.5;
		gc.gridx = 1;
		gc.gridy = 0;
		add(hostTextField, gc);
 
		gc.fill = GridBagConstraints.HORIZONTAL;
		gc.weightx = 2;
		gc.gridx = 2;
		gc.gridy = 0;
		add(generatedLabel, gc);
 
 
		//second row
		gc.fill = GridBagConstraints.HORIZONTAL;
		gc.weightx = 0.5;
		gc.weighty = 1;
		gc.gridx = 0;
		gc.gridy = 1;
		add(interfaceLabel, gc);
 
		gc.fill = GridBagConstraints.HORIZONTAL;
		gc.weightx = 0.5;
		gc.gridx = 1;
		gc.gridy = 1;
		add(interfaceBox, gc);
 
		gc.fill = GridBagConstraints.HORIZONTAL;
		gc.weightx = 0.5;
		gc.weighty = 10;
		gc.gridx = 2;
		gc.gridy = 1;
		add(generatedTextArea, gc);
 
		//third row
		gc.fill = GridBagConstraints.HORIZONTAL;
		gc.weightx = 0.5;
		gc.weighty = 10;
		gc.gridx =0;
		gc.gridy = 2;
		add(Ap, gc);
 
 
 
	}
}

Here is a screen shot of what I have so far:
GBL.jpg

The ActivityPanel has a set width and height of 250 x 450 with a red background(which I did just to see what was going on).

I tried using the GridBagConstraint Constants to no avail.

is there a way to set a margin or padding in between cells?

basically I am lost, I have to use the gridbaglayout, I went through the demo at docs.oracle.com, if someone could point me in the right direction I would appreciate it.

Thanks in advance!
