How can I make my panel wrap text and increase height instead of width when contained in a GridBagLayout?

Oh people. I don't know why this doesn't work in my chat program. But I was able to fix sscce .. with a scrollable implementation where it works now. Thank you all! Code:

    private int row;

    class SomethingPanel extends JPanel implements Scrollable {

        public SomethingPanel(LayoutManager manager){
            super(manager);
        }

        @Override
        public Dimension getPreferredScrollableViewportSize(){
            return getPreferredSize();
        }

        @Override

            return 5;
        }

            return false;
        }

        }
    }

    public MyKskb(){
        JFrame f = new JFrame();
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

                p.setBorder(BorderFactory.createLineBorder(Color.BLACK, 2));
                p.setBackground(Color.GRAY);

                GridBagConstraints gbc = new GridBagConstraints();
                gbc.insets = new Insets(10, 10, 10, 10);

[Question]

I am writing a chat program and the layout looks like this:

The message pane has a gridbaglayout and is wrapped in a JScrollPane. The problem is that if the message is too long, the message bar stretches and becomes too large:

So what I want to achieve is to limit the size of the pane that is wrapped in a jscrollpane - I want the gray message text panes to increase their height if the text gets longer rather than wider. That is, wrap the text without increasing the width of the panel.

Is there a way to achieve this with the ghe grid layout I am missing something? Or should I use a different layout manager?

Edit: Full hierarchy:

JScrollPane
    JPanel (gbl)
        JPanel (custom painting)
            JComponent (JLabel but it can vary)
        JPanel (custom painting)
            JComponent (JLabel but it can vary)
        JPanel (custom painting)
            JComponent (JLabel but it can vary)
        ....    

      

        
        
        
      

    

edit: I tried to implement a scrollable like this:

@Override
    public Dimension getPreferredScrollableViewportSize(){
        return new Dimension(100, getHeight());
    }

    @Override
    public int getScrollableBlockIncrement(Rectangle visibleRect, int orientation, int direction){
        return 5;
    }

    @Override
    public boolean getScrollableTracksViewportHeight(){
        return false;
    }

    @Override
    public boolean getScrollableTracksViewportWidth(){
        return true;
    }

    @Override
    public int getScrollableUnitIncrement(Rectangle visibleRect, int orientation, int direction){
        return 1;
    }

      

        
        
        
      

    

but the same happens if the text is too long ... I don't know what getPreferredScrollableViewportSize should get, but also getSize () did'nt work ...
