I have come across a problem using the XYLayout control that I was
wondering if anybody else has come across.  The problem occurs that when
I add an object to a Panel and initially set it to be invisible
(setVisible to false) that I cannot redisplay this object.  If I
initially set it to visible then I can toggle its "viewability" as often
as I like.  I hope that it is something that I am fundamentally missing,
but it does not appear to be so, because if I change the layout of the
panel to be GridLayout then everything works as expected.
The source code that demonstrates this is attached below:  (if you
change the isViewable in MyClass1 to true the expected behavior occurs,
otherwise I can never get jButton2 to be visible)

Frame1.java:
package untitled2;

import java.awt.*;
import com.sun.java.swing.*;
import java.awt.event.*;
import borland.jbcl.layout.*;

public class Frame1 extends JFrame {
  JPanel jPanel1 = new JPanel();
  XYLayout xYLayout1 = new XYLayout();
  XYLayout xYLayout2 = new XYLayout();
  JButton jButton1 = new JButton();
  JButton jButton2 = new JButton();


  public Frame1() {
    try  {
      jbInit();
    }
    catch (Exception e) {
      e.printStackTrace();
    }
  }
  private void jbInit() throws Exception {
    this.getContentPane().setLayout(xYLayout2);
    this.setSize(600, 500);
    jPanel1.setAutoscrolls(true);
    jButton1.setText("jButton1");
    jButton1.addActionListener(new java.awt.event.ActionListener() {
      public void actionPerformed(ActionEvent e) {
        jButton1_actionPerformed(e);
      }
    });
    jButton2.setText("jButton2");
    jPanel1.setLayout(xYLayout1);
    jButton2.setVisible(MyClass1.isViewable);
    this.getContentPane().add(jPanel1, new XYConstraints(28, 29, 355,
252));
    jPanel1.add(jButton1, new XYConstraints(159, 160, 92, 32));
    jPanel1.add(jButton2, new XYConstraints(148, 112, 132, 37));
  }

  void jButton1_actionPerformed(ActionEvent e) {
     MyClass1.isViewable = !MyClass1.isViewable;
     repaint();
  }

  public void repaint()
  {
    jButton2.setVisible(MyClass1.isViewable);
    super.repaint();

  }
}

MyClass1.java:

package untitled2;

import java.awt.*;
import java.awt.event.*;

public class MyClass1 {
  static boolean isViewable = false;

  public MyClass1() {
  }

  public static void main(String[] args) {
    Frame1 frame = new Frame1();
    frame.setVisible(true);
    frame.addWindowListener(new WindowAdapter() {
      public void windowClosing(WindowEvent e) {
        System.exit(0);
      }
    });

  }

}
