Basic Questions Swing

[brianh]

Hi all,

I am a VB dev by nature but I am tyring to get through a Java course. I need to build a class using swing that places the date in the upper left hand corner. Has an input field for a social security number. Has six inpuit boxes where a person could sign in or out during the day, etc. I just need to get the layout done. But I am haxing a real hard time just getting the labels to display. Here is my code:

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


public class EmpTimeCard extends JFrame
{

  public static void main(String[] args) 
  {
  //first thing we need to do is create a new panel (container)
  JFrame j = new JFrame();
  j.setSize(300,300);
  
  JPanel p1 = new JPanel();
  int cols = 5; 
  int cols1 =15;
  int cols2 = 13;
  //then we need to setup the areas that the text boxes will reside
  JLabel lblLName = new JLabel("Last Name:", JLabel.RIGHT);
  JTextField LName = new JTextField(cols);
  p1.add(lblLName);
  p1.add(LName);
  p1.setVisible(true);
  j.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  j.setVisible(true);
  }

It displays the window, but nothing inside of it. What is going on?

No need to extend JFrame in your case. Swing follows a different containment model then awt so you would have to add any components to the content pane instead of to the JFrame itself.
