GridBagLayout and JScrollPane

[Kay Tracid]

Hi,

I have a JPanel in a JScrollPane. I added the ScrollPane to my Frame. With a borderlayout it works fine, but I must use a GridBagLayout. If I add the ScrollPane to the Frame with a gridbaglayout and i resize the window the ScrollPane has the size of a stamp...
my panel in a ScrollPane:

  JPanel centerPan = new JPanel();
  JScrollPane DataPane = new JScrollPane(centerPan);

in the frame:

  
  
  GridBagLayout MainGridbag = new GridBagLayout();
    GridBagConstraints Maingbc = new GridBagConstraints();
    Maingbc.anchor = GridBagConstraints.NORTHWEST;
    getContentPane().setLayout(MainGridbag);
    Maingbc.gridx = 0;
    Maingbc.gridy = 0;
    MainGridbag.setConstraints(DataPane, Maingbc);
    getContentPane().add(DataPane);

Thanks a lot!

Hi,
In GridBagLayout u got a lot of attributes for the gridbagconstraints class. u had to know the purpose of each of it.
just take a look at the piece of ur code which had been modified and hope it works....
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class gridbag extends JFrame
{
Container cont;
JPanel panel;
JScrollPane scrollpane;
GridBagLayout gridbag;
GridBagConstraints c;
gridbag()
{
cont = getContentPane();
panel = new JPanel();
scrollpane = new JScrollPane(panel);
gridbag = new GridBagLayout() ;
c = new GridBagConstraints() ;
cont.setLayout(gridbag);
c.gridx = 0;
c.gridy = 0;
c.fill = GridBagConstraints.BOTH ;
c.weightx = 1.0 ;
c.weighty = 1.0 ;
gridbag.setConstraints(scrollpane,c) ;
//cont.setLayout(new BorderLayout());
cont.add(scrollpane);
}
public static void main(String a[])
{
gridbag g = new gridbag();
g.setSize(300,300);
g.setVisible(true);
}
}
