Your question is very vague and general - it sounds like you have missed some essential part of your course regarding GUI basics. There are many excellent Swing GUI tutorials on the web, just Google for them. Or start with this tutorial...

Please search for "What is a graphical user interface" and read more about the purpose of a gui. Basically you are going to eliminate "TestClass" and replace it with your "GUI". Click Here to see an example of what someone else who had this assignment did.

To enter data in your table, you are going to need to set CellSelectionEnabled(true); or click on the checkbox in NetBeans. However, from what you wrote, it looks like your instructor wants you to display one record at a time, not multiple records.

I think that it makes it easier to follow the code you posted if you separate your code blocks by class when you post them.

Class 1

//Class 1 code

Class 2

//Class 2 code

Rather than posting all of your code in one code block.

//Class 1

//Class 1 code

//Class 2
//Class 2 code

Code blocks. What I meant by that is to click "</> Code", paste your code for your first class. Click "Insert Code Snippit". Then repeat this for each class. Rather than clicking it once and posting it all together. What will this do? Make it so people are more likely to read your code.

Quoted Text Here

Modify the Inventory Program to use a GUI. The GUI should display the
information one product at a time, including the item number, the name of the product, the number of units in stock, the price of each unit, and the value of the inventory of that product. In addition, the GUI should display the value of the entire inventory, the additional attribute, and the restocking fee.

I looked over everything from the chapters read in last weeks and this weeks class, there is not much discussion on this, only to create a GUI. I have reviewed this site, I did so 2 days ago as well, I just don't get it. I doon't understand why my teacher wants this when we have not learned much of anything about GUIs in this class so far? Idon't understand how to get my GUI to compile and run my code, and I don't know how to connect it to my code.This is killing me and I can't seem to get anyone to help me understand this. I read the book, and I read many online tutorials and watched videos, none of this is helping me, only making it more confusing.

obspsalm22 0 Newbie Poster · Answer 3 · 2014-02-11T22:35:52+00:00

I'm going to try this, this was a bit easier to understand than the tutorials and readings I keep finding. Seperate code blocks? What does this do, if I may ask?

cgeier 187 Junior Poster · Answer 4 · 2014-02-11T23:19:43+00:00

Are you using NetBeans or Eclipse? If so, you may want to check out some tutorials on how to use those programs. Basically, you want to use a JFrame as you have done. Put some buttons (and maybe textboxes) on it. And do something when the buttons are pressed. You have to listen for events (button presses) and take action based on which button was pressed.

cgeier 187 Junior Poster · Answer 5 · 2014-02-11T23:48:47+00:00

You seem to be using NetBeans, so add your button. Then

Right-click on your button, select "Events"
Select "Action"
Select "actionPerformed"

add your code to perform when the button is pressed here.

Here is what NetBeans does:

private javax.swing.JButton jButton1;

//set button text
jButton1.setText("jButton1");

//add event listener
jButton1.addActionListener(new java.awt.event.ActionListener() {
    public void actionPerformed(java.awt.event.ActionEvent evt) {
                jButton1ActionPerformed(evt);
            }
});

//event handler - do this when jButton1 button is pressed
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
        // TODO add your handling code here:


}//jButton1ActionPerformed


private javax.swing.JButton jButton2;
jButton2.setText("jButton2");

//add event listener
jButton2.addActionListener(new java.awt.event.ActionListener() {
    public void actionPerformed(java.awt.event.ActionEvent evt) {
                jButton2ActionPerformed(evt);
            }
});


//event handler - do this when jButton2 button is pressed
private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {                                         
      // TODO add your handling code here:

}//jButton2ActionPerformed

Here is another way to do it:

public class GUI extends JFrame implements ActionListener{

    private javax.swing.JButton jButton1;

    jButton1 = new JButton("jButton1");

    //add listener
    jButton1.addActionListener(this);


    private javax.swing.JButton jButton2;

    jButton2 = new JButton("jButton2");

    //add listener
    jButton2.addActionListener(this);


    //event handler -- this is called when any button is pressed
    public void actionPerformed(ActionEvent event) {

        //determine which button was pressed
        if (event.getSource() == jButton1) {
            //do this when jButton1 button is pressed

            // TODO add your handling code here:

        }//if 
        else if (event.getSource() == jButton2) {
            //do this when jButton2 button is pressed

            // TODO add your handling code here:

        }//else if
    }//actionPerformed

}//class

I think I might understand this, but what button are you speaking about? I have a table and an exit button, are you referring to the table?

cgeier 187 Junior Poster · Answer 7 · 2014-02-12T03:02:07+00:00

I'm not very familiar with using tables in java. You might check this out: Click Here
