Question

I’ve started to create a GUI that consists of a few tabs. Right now I am focusing on two of them. The Pool tab and the Hot Tub tab. When I first started I got everything to work fine on the pool tab. So I figured since all of the label and text box placement would be the same for the Hot Tub tab I would just copy the coding over. Well, I did that and tried naming all the labels and text boxes the same just with the number 2 after them. It’s not working. Now the Hot Tub tab works, but the Pool tab doesn’t, plus the text boxes are gone. I’m also having alignment issues with the text boxes too, but I think that has to do with the naming of the labels and text boxes, I’m not sure.

HOT TUB CLASS:

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;

        HotTub.add( lengthLabel );
    lengthText = new JTextField();
        lengthText.setBounds(260, 15, 150, 20);

        depthLabel.setBounds( 10, 100, 260, 20 );
        HotTub.add( depthLabel );
    depthText = new JTextField();
        depthText.setBounds(260, 100, 150, 20);
        HotTub.add( depthText );
    JLabel volumeLabel = new JLabel("The hot tub's volume is:(ft ^3");
        volumeLabel.setBounds(10, 200, 260, 20);
        HotTub.add( volumeLabel );
        volumeText = new JTextField();
        volumeText.setBounds(260, 200, 150, 20);
        volumeText.setEditable(false);
    HotTub.add(volumeText); 

    JButton calcVolume = new JButton("Calculate Volume");
        calcVolume.setBounds(150,250,150,20);
        calcVolume.addActionListener((ActionListener) this);
        calcVolume.setBackground(Color.white);
        HotTub.add(calcVolume);

    JButton Close = new JButton("Close");
        Close.setBounds(350,250,80,20);
        Close.addActionListener((ActionListener) this);
        Close.setBackground(Color.white);
        HotTub.add(Close);
                           }
}

Right now both the Pool tab and the Hot Tub tab are the same. No matter what tab I’m on, the same results show up on each tab. Is it a naming issue?

Answer 1

in createHotTub() method:

replace HotTub.add( lengthText ); with HotTub.add( lengthText2 );

replace HotTub.add( widthText ); with HotTub.add( widthText2 );

replace HotTub.add( depthText ); with HotTub.add( depthText2 );

replace HotTub.add( volumeText ); with HotTub.add( volumeText2 );
