GUI bafflement

[Steve.Ball at avis-europe.com]

Hi all,

 

I'm trying to implement the basic client in a multiple document application.
I'm not using JInternalFrames, since that would require some serious
modification of the mindterm code (as far as I can see) and I'm not quite
ready for that yet ...

 

I've got this far: my application's main page loads fine, then as a test,
spawns a new JFrame and makes itself invisible. The new JFrame hosts the
mindterm client and makes itself visible (just like in the BasicClient.java
example). This works fine, and when I close that window, the original main
window reappears quite happily.

 

If, however, I audaciously try and do the *exact same call* from another
place, a blank JFrame appears and will not close. Has anyone seen this
before?

 

<Code from main window>

 

private void doNewWindow(String serverName)

      {

            System.out.println("Doing new window");

            ServerInfo server =
settings.getServerList().getServerInfo(serverName);

            this.setVisible(false);

            new SSHTerminalWindow(this, settings, server);

      }

 

<This is the MouseListener attached to a JList that calls this method>

 

lstServerList.addMouseListener(new MouseAdapter()

            {

                  public void mouseClicked(MouseEvent e)

                  {

                        if (e.getClickCount() == 2)

                        {

                              String selected =
lstServerList.getSelectedValue().toString();

                              System.out.println(selected);

                              doNewWindow(selected);

                        }

                  }

            });

 

<First bit of SSHTerminalWindow - note resemblance to BasicClient example>

 

public class SSHTerminalWindow extends JFrame

{

      private static final long serialVersionUID = 234982345l;

      

    private SSH2Transport      transport;

    private SSH2SimpleClient   client;

    private SSH2ConsoleRemote  console;

    private LineReaderTerminal lineReader;

    

    public SSHTerminalWindow(MainWindow main, Settings settings, ServerInfo
target)

    {

      super("SSH terminal");

      

      TerminalWin terminal = null;

      

      try

      {

                  terminal = new TerminalWin(this);

                  RandomSeed seed = new RandomSeed();

              terminal.addAsEntropyGenerator(seed);

              

              setLayout(new BorderLayout());

              add(terminal.getPanelWithScrollbar(),

                        BorderLayout.CENTER);

      

              TerminalFrameTitle frameTitle =

                  new TerminalFrameTitle(this, "SSH-ing into " +

                              target.getServerName());

              frameTitle.attach(terminal);

              

              terminal.setClipboard(GlobalClipboard.getClipboardHandler());

              

              addWindowListener(new WindowAdapter()

                        {

                              /**

                               * Overide corresponding function in
java.awt.event.WindowAdapter

                               */

                              public void windowClosing(WindowEvent e)

                              {

                                    System.out.println("Caught window close
event");

                                    if(lineReader != null)
{lineReader.breakPromptLine("");}

            

                                    if(console != null) { console.close();}

            

                                  if(transport != null)

                                  {

                                      transport.normalDisconnect("User
disconnects");

                                  }

                              }

                        });

      

//            pack();

              System.out.println("Making SSH terminal visible");

              this.setVisible(true);

              //main.setVisible(false);

              setSize(300,300);

              setLocation(44,50);

 


Many thanks in advance,

 

Steve Ball
