Menu
I am creating a POS system and have the GUI complete, but now I am having a hard time figuring out how to get the item to display once the item code is input. Here is my code:
import javax.swing.JFrame;
import javax.swing.JButton;
import java.text.NumberFormat;
import java.awt.event.*;
public class PosGUI extends javax.swing.JFrame {
public PosGUI() {
initComponents();
}
@SuppressWarnings(“unchecked”)
private void initComponents() {
total = new javax.swing.JButton();
Enter = new javax.swing.JButton();
ItemCodeNumber = new javax.swing.JLabel();
ItemCode = new javax.swing.JTextField();
DisplayItemNamePrice = new javax.swing.JLabel();
SubTotal = new javax.swing.JLabel();
SalesTax = new javax.swing.JLabel();
TotalPurchase = new javax.swing.JLabel();
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
setTitle(“Point of Sale”);
total.setText(“Total”);
total.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
totalActionPerformed(evt);
// I know that my action needs to be input here so when the Total button is pushed it knows what to do, but I do
//not know where to start. Help!///
}
});
Enter.setText(“Enter”);
ItemCode.setText(“Item Code”);
DisplayItemNamePrice.setText(“Item Name: Item Price:”);
SubTotal.setText(“Sub Total:”);
SalesTax.setText(“Sales Tax:”);
TotalPurchase.setText(“Total:”);
javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
getContentPane().setLayout(layout);
layout.setHorizontalGroup(
layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
.addGroup(layout.createSequentialGroup()
.addGap(88, 88, 88)
.addGroup(layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
