JScrollPane problem

Hi All,

I'm trying to set the scrollbar to the top as it is always at the bottom. Nothin I try seems to work!!

I have a JFrame with a container:

I then add my panels

createJScrollPane() returns a JScrollPane containing an outer JPanel inside which there are a number of other panels

I cannot figure out why any of the methods I have tried will not work

Any help greatly appreciated.
Thanks,
Stephen.

can you post createJScrollPane()

Hi,

Here it is:

private JScrollPane createJScrollPanel() 
    { 
        JPanel questionPnl = new JPanel(new GridLayout(numOfQuestions,1));
        
        // Add questions
        JPanel[] box = new JPanel[numOfQuestions];
        JLabel[] dummylbl = new JLabel[numOfQuestions];
        int numberOfButtons = 0;
        radioButtons = new JCheckBox[36];
        JTextArea[] descriptionTxt = new JTextArea[36];
        JTextPane[] questTxt = new JTextPane[9];
        JPanel[] ansPnl = new JPanel[36];
        JPanel[] questPnl = new JPanel[9];
        
        for(int a = 0; a <= numOfQuestions-1; a++)
        {
            if(numberOfButtons <=36)
            {
            System.out.println("Creating buttons");
    
            box[a] = new JPanel(); 
    box[a].setLayout(new BoxLayout(box[a], BoxLayout.PAGE_AXIS));

// Get Question and answers
    questTxt[a] = new JTextPane();
    questTxt[a].setFont(new Font( "Serif", Font.BOLD, 14));
    questTxt[a].setText("Q "+Integer.toString(a+1)+".  "+getQuestions(a));
    questTxt[a].setEditable(false);
    questTxt[a].setBackground(Color.LIGHT_GRAY);
    questPnl[a] = new JPanel(new BorderLayout());
    questPnl[a].add(questTxt[a], BorderLayout.WEST);
    questPnl[a].setBackground(Color.LIGHT_GRAY);

box[a].add(questPnl[a]);
                
    radioButtons[numberOfButtons] = new JCheckBox();
    radioButtons[numberOfButtons].setBackground(Color.LIGHT_GRAY);
    descriptionTxt[numberOfButtons] = new JTextArea(getAnswers(a,0));
    descriptionTxt[numberOfButtons].setEditable(false);
    descriptionTxt[numberOfButtons].setBackground(Color.LIGHT_GRAY);
    radioButtons[numberOfButtons].setActionCommand("Q"+Integer.toString(a+1)+"a");
            ansPnl[numberOfButtons] = new JPanel(new BorderLayout());
            ansPnl[numberOfButtons].add(radioButtons[numberOfButtons],BorderLayout.WEST);
            ansPnl[numberOfButtons].add(descriptionTxt[numberOfButtons],BorderLayout.CENTER);
            
                    box[a].add(ansPnl[numberOfButtons]);
    numberOfButtons++;
        
    .
    .
    .//Above repeated 3 time  
    
   // Filler at end of box
   dummylbl[a] = new JLabel();
   dummylbl[a].setPreferredSize(new Dimension(50,20));
   box[a].add(dummylbl[a]);
        
   // Add question box to Question Panel 
   questionPnl.add(box[a]);
            }
        }
 
        voteButton = new JButton("Submit Answers");
        voteButton.setPreferredSize(new Dimension(100,25));
        voteButton.addActionListener(new ActionListener() 
        { 
            public void actionPerformed(ActionEvent e) 
            { 
                System.out.println("Action Performed");
                .
                .
                .// Deal with check box values
                return; 
            } 
        }); 
         
        
        //Add Question Panel to Scrollpane        
        JScrollPane qaPane = new JScrollPane();
        qaPane.getViewport().add(questionPnl);
        qaPane.getViewport().setBackground(Color.LIGHT_GRAY);
        qaPane.getViewport().setViewPosition(new Point(0, 0));
                
        return qaPane;
    }

Hi Michael,

Thanks for your help, the problem was a silly one. I was setting the frame visible before I added the JScrollPane
:roll:

Thanks again.
Stephen.
