Hi Guys
THis is for Part 4 of my inventory program. I needed to create GUI interface. I have coded a GUI which is below not sure if its right or not. But I can not figure out how to call this in my main file Please help me I know the answer is prob so simple I am just lost.

here is my gui code
import java.util.Arrays;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
//a liitle GUI
class GUI extends JFrame {
protected double currentProdno;
private JTextField jtfprdItem; //1
private JTextField jtfprdName; //2
private JTextField jtfprdUnit; //3
private JTextField jtfprdPrice;//4
private JTextField jtfTotal; //5 getresult()
private JTextField jtfReStock; //6 getrestock()
private JTextField jtfstrCName;//7
private JTextField jtfinvTotal;//8
private JButton btnNext;

GUI() {
super("Inventory Part 4 Program");
//this.inventory = inventory;
currentProdno = 0;

JPanel jp;
JLabel jl;
JPanel outerPanel = new JPanel();
outerPanel.setLayout(new BoxLayout(outerPanel, BoxLayout.Y_AXIS));

JPanel titlePanel = new JPanel();
titlePanel.setLayout(new FlowLayout(FlowLayout.CENTER));
jl = new JLabel("Inventory Part 4");
titlePanel.add(jl);
outerPanel.add(titlePanel);

JPanel numberPanel = new JPanel();
numberPanel.setLayout(new FlowLayout(FlowLayout.LEFT));
jl = new JLabel(" Number: " );
numberPanel.add(jl);
jtfprdItem = new JTextField (1);
jtfprdItem.setEditable(false);
numberPanel.add(jtfprdItem);
outerPanel.add(numberPanel);

JPanel number1Panel = new JPanel();
number1Panel.setLayout(new FlowLayout(FlowLayout.LEFT));
jl = new JLabel(" Name: " );
number1Panel.add(jl);
jtfprdName = new JTextField (2);
jtfprdName.setEditable(false);
number1Panel.add(jtfprdName);
outerPanel.add(number1Panel);

JPanel number2Panel = new JPanel();
number2Panel.setLayout(new FlowLayout(FlowLayout.LEFT));
jl = new JLabel(" Units: " );
number2Panel.add(jl);
jtfprdUnit = new JTextField(3);
jtfprdUnit.setEditable(false);
number2Panel.add(jtfprdUnit);
outerPanel.add(number2Panel);

JPanel number3Panel = new JPanel();
number3Panel.setLayout(new FlowLayout(FlowLayout.LEFT));
jl = new JLabel(" Price: " );
number3Panel.add(jl);
jtfprdPrice = new JTextField(4);
jtfprdPrice.setEditable(false);
number3Panel.add(jtfprdPrice);
outerPanel.add(number3Panel);

JPanel number4Panel = new JPanel();
number4Panel.setLayout(new FlowLayout(FlowLayout.LEFT));
jl = new JLabel(" Total: $ " );
number4Panel.add(jl);
jtfTotal = new JTextField(5);
jtfTotal.setEditable(false);
number4Panel.add(jtfTotal);
outerPanel.add(number4Panel);

JPanel number5Panel = new JPanel();
number5Panel.setLayout(new FlowLayout(FlowLayout.LEFT));
jl = new JLabel("Restocking Fee: $ " );
number5Panel.add(jl);
jtfReStock = new JTextField(6);
jtfReStock.setEditable(false);
number5Panel.add(jtfReStock);
outerPanel.add(number5Panel);

JPanel number6Panel = new JPanel();
number5Panel.setLayout(new FlowLayout(FlowLayout.LEFT));
jl = new JLabel("Restocking Fee: $ " );
number5Panel.add(jl);
jtfstrCName = new JTextField(7);
jtfstrCName.setEditable(false);
number5Panel.add(jtfstrCName);
outerPanel.add(number6Panel);

JPanel number7Panel = new JPanel();
number6Panel.setLayout(new FlowLayout(FlowLayout.CENTER));
jl = new JLabel("Total Invenory Value: $" );
number6Panel.add(jl);
jtfTotal = new JTextField(8);
jtfTotal.setEditable(false);
outerPanel.add(number7Panel);



setContentPane(outerPanel);
setResizable(false);
setVisible(true);

}



} // end GUI class



here is my main code
public class Inventory
{
public static void main(String args[])
{
Movie Products[] = new Movie[4];

Products[0] = new Movie("0", "Little Mermaid",26, 12.99, "G");
Products[1] = new Movie("1", "A Walk to Remember",15, 15.89, "PG");
Products[2] = new Movie("2", "Men in Black",8, 5.00, "PG");
Products[3] = new Movie("3", "Boyz in the hood",20, 21.15, "PG13");

//initiate decimal format object
DecimalFormat Currency = new DecimalFormat("#0.00");

//print the inventory information
System.out.print("\nInventory of DVD Movies:\n\n");

for(int index = 0; index < Products.length; index++) {
System.out.println("Number: " + Products[index].getNum());
System.out.println("Name: " + Products[index].getName());
System.out.println("Rating: " + Products[index].getRating());
System.out.println("Stock: " + Products[index].getStock());
System.out.println("Price: $" + Currency.format(Products[index].getPrice()));
System.out.println("Restocking fee: $" + Currency.format(Products[index].getRestockingFee()));
System.out.println("Item Value: $" + Currency.format(Products[index].getInventoryTotal()));
}

//sorting the array
ProductInfo.SortInventory(Products);

//print the inventory information
System.out.print("\nSorted Inventory of DVD Movies:\n\n");

for(int index = 0; index < Products.length; index++) {
System.out.println("Number: " + Products[index].getNum());
System.out.println("Name: " + Products[index].getName());
System.out.println("Rating: " + Products[index].getRating());
System.out.println("Stock: " + Products[index].getStock());
System.out.println("Price: $" + Currency.format(Products[index].getPrice()));
System.out.println("Restocking fee: $" + Currency.format(Products[index].getRestockingFee()));
System.out.println("Item Value: $" + Currency.format(Products[index].getInventoryTotal()));
}

//calulcating total value and displaying
Double totalInv = Products[0].CalculateTotalInventoryValue(Products);
System.out.print("Total Inventory Value: $" + Currency.format(totalInv) + "\n");

// Import the java swing package so we can use swing controls like JFrame.

// Create a JFrame (application window with the title "HelloWorldSwing")
JFrame frame = new JFrame("Inventory Of DVD's");

// Set it so that it terminates the program when the window is closed.
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

// Set the windows size and then show it.
frame.setSize(300,300);
frame.setVisible(true);

} // main

} // Inventory

if you create a class for your GUI.. just create a new instance of it in the main..

Thank you is that not what I did on line 171 i think????

Please post your code like this

In your GUI class you have the call to the setSize() method missing



You Inventory contains only one static method main()
You do not really create an Inventory object.. so you can just cut&paste your main() method from Inventory and put it in the GUI class.

If you want to keep (for emotional reasons) your old Inventory class it is ok keep it.

Remove your JFrame ..... stuff and add



In your GUI class you will need a method to receive the movies



You will eventually need a button to switch from one movie to another

Aww.. sorry for that.. I never taught that your GUI is actually just a JFrame..

well indeed you create a JFrame.. I can see it clearly.. but where exactly did you create an instance of your GUI CLASS..

like what pbl said..

GUI gui = new GUI() ; << something like this..

I am confused on this part I now get a window but it doesnt display what i have in the array. I am so confused.

Ok on your main() you should do



Now in you GUI you have to receive the Movie and display it

I do not have a movie class above is my main program with th emovie array is that what u mean? I am so sorry about all the questions this stuff is confusing for non java people. But you have been so helpful.

OK you can remove that vecause you use an instance of GUI as JFrame

JFrame fram = new JFrame ();


And sorry your array of Movies is called Products[]

so

gui.setMovie(Products);

i know u must be ready to kill me
ok so I removed that and also put in gui.setMovie(Products);

I get this error


C:\Documents and Settings\paccda\Desktop\Inventory.java:60: cannot find symbol
symbol : method setMovie(Movie[])
location: class GUI
gui.setMovie(Products);
^
1 error

Tool completed with exit code 1



and in my gui code I get these errors
C:\Documents and Settings\paccda\Desktop\InventoryButtons.java:125: cannot find symbol
symbol : method display()
location: class GUI

C:\Documents and Settings\paccda\Desktop\InventoryButtons.java:134: cannot find symbol

Repost you code
you obviously have a typo
