How to Resize JScrollPane used in a JPanel?

[Raja Sekhara]

Hi ,

I am adding a scroll pane of textArea to a JPanel. And this JPanel is added to another Panel where I can have a tablepanel(a component)

Its like a panel consisting of tablepanel and JPanel .

Can you help me with this?

I am not able to resize the panel / scroll pane (by dragging the edge of scroll pane, so that I can see the whole decription(when its abundant) of property without using scroll bars.)


Code :

private JPanel createPanel() {
final JTextArea textArea = getNewTextArea();
//gets text area of properties description. Dynamically changes
// when upon selection of particular property
textArea.setBackground(Color.GREY);
textArea.setRows(4);
textArea.setText("Description of property set here.");
final JScrollPane scrollPane = new JScrollPane(textArea,
JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED,
JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);
scrollPane.setPreferredSize(new Dimension(600, 60));
JPanel panel = new JPanel();
panel.setLayout(new BorderLayout());
panel.add(scrollPane, BorderLayout.CENTER);
panel.setPreferredSize(new Dimension(50, 40));
panel.setVisible(true);

return panel;
}

you'll need to experiment with different layout managers

e.g. run this, and it should display what I think you are describing,
then swap the new JPanel() lines, recompile and rerun

    
import javax.swing.*;
import java.awt.*;
class Testing
{
  public void buildGUI()
  {
    JFrame f = new JFrame();
 
    //JPanel p = new JPanel(new BorderLayout());//<---swap this line
    JPanel p = new JPanel();//<---for this line
 
    p.add(createPanel());
    f.getContentPane().add(p);
    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    f.pack();
    f.setLocationRelativeTo(null);
    f.setVisible(true);
  }
  private JPanel createPanel() {
    final JTextArea textArea = new JTextArea();
    //gets text area of properties description. Dynamically changes
    // when upon selection of particular property
    textArea.setBackground(Color.GRAY);
    textArea.setRows(4);
    textArea.setText("Description of property set here.");
    final JScrollPane scrollPane = new JScrollPane(textArea,
    JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED,
    JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);
    scrollPane.setPreferredSize(new Dimension(600, 60));
    JPanel panel = new JPanel();
    panel.setLayout(new BorderLayout());
    panel.add(scrollPane, BorderLayout.CENTER);
    panel.setPreferredSize(new Dimension(50, 40));
    panel.setVisible(true);
 
    return panel;
  }
  public static void main(String args[]){new Testing().buildGUI();}
}
