Positioning components?

[Dillinger4]

Im trying to create and layout controls
dynamically but i can't figure out how
to set the x and y alignments.
I tried using setalignmentX and using
setPosition(Point); Any ideas?

  import java.awt.*; 
  import javax.swing.*;
  import java.awt.event.*; 


   public class Layout{
     public static void main(String [] args){
   
     int width = 50;
     int space = 10;
     float x = 0; 
     float y = 0;
     JFrame jf = new JFrame("Hello");
     Dimension d; 
     Container c = jf.getContentPane();
     c.setLayout(null);
     jf.addWindowListener(new WindowMonitor()); 
     jf.setSize(600,450); 
     jf.setVisible(true);   

     JButton[] jb = new JButton[20];
     for(int i = 0; i < jb.length; ++i){
       jb[i] = new JButton(new Integer(i).toString());
       d = new Dimension(50,50);
       jb[i].setSize(d);
        
    }
      for(int i = 0; i < jb.length; ++i){
     
       if(x > jf.getWidth() - (width + space)){
        x = 10;
        y = 60;
       jb.setalignmentX = x;     
       jb.setalignmentY = y;       

       c.add(jb[i]); 
       }else{x += (width + space);
           jb.setalignmentX = x;     
            c.add(jb[i]); 
     }
    }
   }
  }

 class WindowMonitor extends WindowAdapter {
     public void windowClosing(WindowEvent we){
       System.exit(0);
    } 
   }

have you tried setBounds?

I'm quite interested in this as I haven't had a chance of playing with the layout manager set to null.

DO keep us updated!

Here you hav an example:
jScrollPane2.setVerticalScrollBarPolicy
(javax.swing.JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
jScrollPane2.setBorder(BorderFactory.createTitledBorder("Tekst"));
jScrollPane2.setBounds(new Rectangle(0, 108, 634, 156));
jScrollPane2.getViewport().add(jTextArea2, null);
this.getContentPane().add(jScrollPane2, null);
jTextArea2.setWrapStyleWord(true);
jTextArea2.setLineWrap(true);
jTextArea2.setBorder(BorderFactory.createLineBorder(Color.black, 1));

Thanks guys The methods worked good. I have
the JFrame set to a certain width which gives the
right most JButtons a nice space from the edge of
the frame. But i have to work on the line
" if(x > (jf.getWidth() - (width + space))){"
a bit so i can have consistent space from the
edge of the frame regardless of the JFrame size.
