    First of all, I know that winico is there. The purpose of doing it myself
    is to help me to better understand the programming model of Tcl/Tk and
    compare them with Java. Also, it seems that winico follows different
    approach from mine for handling this issue.

    I developed a Java JNI class dealing with System tray on Windows myself.
    Now, I want to move my code from Java to Tk. Every thing is fine until the
    last step of my code requires the following loop.

    This loop is fine for Java since Java is multithreaded. Java won't wait
    for the completion of an command and continue to execute the other stuff.
    Thus, having such an event loop in JNI is fine for Java. However, Tcl/Tk
    is single-threaded by default. It seems to me that Tk uses some loops to
    handle its own messages. However, I have to deal with the event loops for
    the Windows system tray. Is there any way that I can add this message loop
    to the Tk's own event loop? Or is there any better solution for this
    kind of problems?

    Sincerely hope that some one can help me out. Thanks a lot in advance!

    ========================================
        MSG msg; BOOL bRet;
        // Start the message loop.
        while((bRet = GetMessage(&msg, NULL, 0, 0)) != 0)
        {
            if (bRet == -1)
            {
                // handle the error and possibly exit
            }
            else
            {
                TranslateMessage(&msg);
                DispatchMessage(&msg);
            }
        }
