linking GUI with program

Possibly a good idea to post the code, but please post a link to it if possible

How would I post a link to it?

In public webspace of use http://pastebin.com

You basically need to have public set methods to set the fields from input

You can use the classes from your command line app in the same way you use any classes.
So just use them in your GUI as you need them.

Ok i will give that a go and get back to you in a bit.

Thank you

When I run the GUI with the same class in my program from the command line it brings up the error:

The error is
JobApplication.java:187: cannot find symbol
symbol  : constructor Job(javax.swing.JTextField,javax.swing.JTextField,javax.swing.JTextField,javax.swing.JTextField,javax.swing.JTextField)
location: class Job
   Job job = new  Job(Id, Customer, Paid, MaterialCost, LabourCost);

However with the program that runs from the command line it compiles are doesnt seem to have a problem.

If you need an int you use something like:

int id = Integer.parseInt(Id.getText());

you'll find other conversions here:

http://www.objects.com.au/java/conversions.do

Its compiled
thank you

is there a way to check that it is working in the GUI?

maybe add some debug println() to your Job class to see what values it gets

If you don't already have a toString method in Job, provide an implementation that prints the fields:

System.out.println(job);

will show everything (where 'job' is the appropriate reference)

Ah ok thank you

one last question:

Is there a way for the fields to empty once the user has clicked add job

the code for add job is:

public void actionPerformed(ActionEvent e)
{
                 String text1 = Id.getText();
       String text2 = Customer.getText();
       String text = Paid.getText();
                 Double.parseDouble(MaterialCost.getText());
        Double.parseDouble(LabourCost.getText());



                String actionCommand = e.getActionCommand();
      if(e.getSource() instanceof JMenuItem)
      if("AddJob".equals(actionCommand))
      addFJob();

}
      

public  void addFJob()
{

      Job job = new  Job(Id.getText(), Customer.getText(), Paid.getText(),  Double.parseDouble(MaterialCost.getText()), Double.parseDouble(LabourCost.getText()));
        collection.addFJob(job);

}

You need to call setText("");

on your text fields

public  void addFJob()
{

     Job job = new  Job(Id.getText(), Customer.getText(), Paid.getText(),  Double.parseDouble(MaterialCost.getText()), Double.parseDouble(LabourCost.getText()));
        collection.addFJob(job);
        Id.setText("");
        Customer.setText("");
        Paid.setText("");
        MaterialCost.setText("");
        LabourCost.setText("");


}

I've tried writing the code but it doesnt clear them.

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

public class JobApplication extends JFrame implements ActionListener

I've posted the code above if that helps... :)

thank you

delete the following lines from your constructor:

     JTextField Id;
     JTextField Customer;
     JTextField Paid;          
     JTextField MaterialCost;
     JTextField LabourCost;

They are shadowing the member variables

I've changed what u suggested but its still not refreshing

Do i need to add mouselisteners in to the program. If so how do I go about doing it?

Thank you it works now

I will split the points between you and objects as you both deserve them :)

OK - glad i could help

:-)

no worries :)
