create a simple modal dialog box with a textfield contained within it.

create a menuitem along with a shortcut that will spawn this modal dialog.

try to type in the dialog's textfield.

here is some sample code:
//*********************************
import java.awt.*;
import java.awt.event.*;

public class testModal extends Frame implements ActionListener
{
  private MenuItem makeDialog;
  private IndentDialog indent;

  public static void main(String[] args)
  {
    testModal thisapp = new testModal();
  }

  public testModal()
  {
    super("test modality");
    MenuBar mb = new MenuBar();
    Menu test = new Menu("test");
    test.add(makeDialog = new MenuItem("makeDialog", new MenuShortcut('m')));
    mb.add(test);
    setMenuBar(mb);

    addWindowListener(new WindowAdapter() {
      public void windowClosing(WindowEvent e) {
        System.exit(0);
      }
    });

    makeDialog.addActionListener(new ActionListener() {
      public void actionPerformed(ActionEvent e) {
        indent = new IndentDialog(this, "", true);
      }
    });

    setBounds(100, 100, 200, 100);
    setVisible(true);
  }
}
//****************************************
public class IndentDialog extends Dialog implements ActionListener
{
  TextField indentSize;
  Label pixels;
  Button ok, cancel;
  int size;

public IndentDialog(Frame f, String title, boolean modal)
{
super(f,title,modal);
setLayout(new BorderLayout());
setResizable(false);
setSize(200,100);
setLocation(300,300);
Panel buttons = new Panel();
buttons.setLayout(new FlowLayout(FlowLayout.CENTER));
buttons.add(ok= new Button("OK"));
buttons.add(cancel = new Button("Cancel"));

Panel topPanel = new Panel();
topPanel.setLayout(new FlowLayout(FlowLayout.CENTER));
topPanel.add(pixels = new Label("Pixels:", Label.CENTER));
topPanel.add(indentSize= new TextField(10));
add("Center", topPanel);
add("South", buttons);

size = 0;
this.addWindowListener(new WinAdapter(false, false));
ok.addActionListener(this);
cancel.addActionListener(this);
}

public void actionPerformed(ActionEvent e)
{
if(e.getActionCommand() == "OK")
{
if(indentSize.getText().length() <= 0) return;
try
{
size = (new Integer(indentSize.getText())).intValue();
}
catch(NumberFormatException ex)
{
indentSize.setText("integral values only");
return;
}
indentSize.setText("");
setVisible(false);
dispose();
}
if(e.getActionCommand() == "Cancel")
{
size = -1;
indentSize.setText("");
setVisible(false);
dispose();
}
}
public int getIndentSize() {return size;}
}

======================================================================
Another report: (see ATTACHMENTS for code example)

I have modal dialog containing "OK"/"Cancel" buttons
together with TextField. This dialog is connected
with menu item. When I choose this menu item with mouse or keyboard,
dialog works, bu if I use shortcut, input to TextField locks, and
beeps are sent to speaker. When I recompiled
my classes with jdk1.1.3/1.1.2/1.1.1 everithing works
perfectly.
2nd: I cannot use comma,+,- (i.e. not-letter symbols)
for menu shortcuts.
